- phplovesong 7mo agoHoe much power did it take to train the models?
- freeqaz 7mo agoI would honestly guess that this is just a small amount of tweaking on top of the Sonnet 4.x models. It seems like providers are rarely training new 'base' models anymore. We're at a point where the gains are more from modifying the model's architecture and doing a "post" training refinement. That's what we've been seeing for the past 12-18 months, iirc.
- squidbeak 7mo ago> Claude Sonnet 4.6 was trained on a proprietary mix of publicly available information from the internet up to May 2025, non-public data from third parties, data provided by data-labeling services and paid contractors, data from Claude users who have opted in to have their data used for training, and data generated internally at Anthropic. Throughout the training process we used several data cleaning and filtering methods including deduplication and classification. ... After the pretraining process, Claude Sonnet 4.6 underwent substantial post-training and fine-tuning, with the intention of making it a helpful, honest, and harmless1 assistant.
- phplovesong 7mo agoNope. They need to update/retrain older base models regularily. Take Programming as an example, the field evolves faster than anything else. Stuff from last year will be outdated today.
- neural_thing 7mo agoDoes it matter? How much power does it take to run duolingo? How much power did it take to manufacture 300000 Teslas? Everything takes power
- vablings 7mo agoThe biggest issue is that the US simply Does Not Have Enough Power, we are flying blind into a serious energy crisis because the current administration has an obsession with "clean coal"
- phplovesong 7mo agoAlso known as "trump coal" its so clean its white.
- bronco21016 7mo agoI think it does matter how much power it takes but, in the context of power to "benefits humanity" ratio. Things that significantly reduce human suffering or improve human life are probably worth exerting energy on. However, if we frame the question this way, I would imagine there are many more low-hanging fruit before we question the utility of LLMs. For example, should some humans be dumping 5-10 kWh/day into things like hot tubs or pools? That's just the most absurd one I was able to come up with off the top of my head. I'm sure we could find many others. It's a tough thought experiment to continue though. Ultimately, one could argue we shouldn't be spending any more energy than what is absolutely necessary to live. (food, minimal shelter, water, etc) Personally, I would not find that enjoyable way to live.

- phplovesong 7mo agoOfc it matters. Who pays for the power? Does the AI pay for the data or the power they use for training? Nope, they dont. Consumers pay for the power in rising enerfy bills, while the AI datacenters get huge gov subsidies. At the same time people get booted because some CTO has gone full blown AI blind. Its a bad situation for the consumer.

- nubg 7mo agoMy take away is: it's roughly as good as Opus 4.5. Now the question is: how much faster or cheaper is it?
- vidarh 7mo agoGiven that the price remains the same as Sonnet 4.5, this is the first time I've been tempted to lower my default model choice.
- eleventyseven 7mo ago> That's a long document. Probably written by LLMs, for LLMs
- freeqaz 7mo agoIf it maintains the same price (with Anthropic tends to do or undercuts themselves) then this would be 1/3rd of the price of Opus. Edit: Yep, same price. "Pricing remains the same as Sonnet 4.5, starting at $3/$15 per million tokens."
- Bishonen88 7mo ago3 is not 1/3 of 5 tho. Opus costs $5/$25
- sxg 7mo agoHow can you determine whether it's as good as Opus 4.5 within minutes of release? The quantitative metrics don't seem to mean much anymore. Noticing qualitative differences seems like it would take dozens of conversations and perhaps days to weeks of use before you can reliably determine the model's quality.
- johntarter 7mo agoJust look at the testimonials at the bottom of introduction page, there are at least a dozen companies such as Replit, Cursor, and Github that have early access. Perhaps the GP is an employee of one of these companies.

- handfuloflight 7mo agoLook at these pelicans fly! Come on, pelican!
- belinder 7mo agoIt's interesting that the request refusal rate is so much higher in Hindi than in other languages. Are some languages more ambiguous than others?
- longdivide 7mo agoArabic is actually higher, at 1.08% for Opus 4.6
- vessenes 7mo agoOr some cultures are more conservative? And it's embedded in language?
- phainopepla2 7mo agoOr maybe some cultures have a higher rate of asking "inappropriate" questions
- vessenes 7mo agoAccording to whom, though, good sir?? I did a little research in the GPT-3 era on whether cultural norms varied by language - in that era, yes, they did

- serf 7mo ago>we're just teaching them how to pass a polygraph. I understand the metaphor, but using 'pass a polygraph' as a measure of truthfulness or deception is dangerous in that it alludes to the polygraph as being a realistic measure of those metrics -- it is not.
- nwah1 7mo agoThat was the point. Look up Goodhart's Law
- madihaa 7mo agoA polygraph measures physiological proxies pulse, sweat rather than truth. Similarly, RLHF measures proxy signals human preference, output tokens rather than intent. Just as a sociopath can learn to control their physiological response to beat a polygraph, a deceptively aligned model learns to control its token distribution to beat safety benchmarks. In both cases, the detector is fundamentally flawed because it relies on external signals to judge internal states.
- AndrewKemendo 7mo agoI have passed multiple CI polys A poly is only testing one thing: can you convince the polygrapher that you can lie successfully
- handfuloflight 7mo agoSituational awareness or just remembering specific tokens related to the strategy to "play dead" in its reasoning traces?
- marci 7mo agoImagine, a llm trained on the best thrillers, spy stories, politics, history, manipulation techniques, psychology, sociology, sci-fi... I wonder where it got the idea for deception?
- dpe82 7mo agoIt's wild that Sonnet 4.6 is roughly as capable as Opus 4.5 - at least according to Anthropic's benchmarks. It will be interesting to see if that's the case in real, practical, everyday use. The speed at which this stuff is improving is really remarkable; it feels like the breakneck pace of compute performance improvements of the 1990s.
- iLoveOncall 7mo agoGiven that users prefered it to Sonnet 4.5 "only" in 70% of the cases (according to their blog post) makes me highly doubt that this is representative of real-life usage. Benchmarks are just completely meaningless.
- jwolfe 7mo agoFor cases where 4.5 already met the bar, I would expect 50% preference each way. This makes it kind of hard to make any sense of that number, without a bunch more details.
- gnatolf 7mo agoGood point. So much functionality gets commoditized, we have to move goalposts more or less constantly.

- nozzlegear 7mo ago> In areas where there is room for continued improvement, Sonnet 4.6 was more willing to provide technical information when request framing tried to obfuscate intent, including for example in the context of a radiological evaluation framed as emergency planning. However, Sonnet 4.6’s responses still remained within a level of detail that could not enable real-world harm. Interesting. I wonder what the exact question was, and I wonder how Grok would respond to it.

- dang 7mo agoPlease don't post unsubstantive comments.
- simianwords 7mo agoI wonder what difference have people found with sonnet 4.5 and opus 4.5 and probably similar delta will remain. Was sonnet 4.5 much worse than opus?
- dpe82 7mo agoSonnet 4.5 was a pretty significant improvement over Opus 4.
- simianwords 7mo agoYes but it’s easier to understand difference between 4.5 sonnet and opus and apply that difference to opus 4.6
- deleted 7mo ago[deleted]
- stopachka 7mo agoHas anyone tested how good the 1M context window is? i.e given an actual document, 1M tokens long. Can you ask it some question that relies on attending to 2 different parts of the context, and getting a good repsonse? I remember folks had problems like this with Gemini. I would be curious to see how Sonnet 4.6 stands up to it.
- simianwords 7mo agoDid you see the graph benchmark? I found it quite interesting. It had to do a graph traversal on a natural text representation of a graph. Pretty much your problem.
- quacky_batak 7mo agoWith such a huge leap, i’m confused why they didn’t call it Sonnet 5? As someone who uses Sonnet 4.5 for 95% tasks due to costs, i’m pretty excited to try 4.6 at the same price
- Retr0id 7mo agoIt'd be a bit weird to have the Sonnet numbering ahead of the Opus numbering. The Opus 4.5->4.6 change was a little more incremental (from my perspective at least, I haven't been paying attention to benchmark numbers), so I think the Opus numbering makes sense.
- Sajarin 7mo agoSonnet numbering has been weirder in the past. Opus 3.5 was scrapped even though Sonnet 3.5 and Haiku 3.5 were released. Not to mention Sonnet 3.7 (while Opus was still on version 3) Shameless source: https://sajarin.com/blog/modeltree/ https://sajarin.com/blog/modeltree/
- cobolexpert 7mo agoI like this tree visualization! The background with little squares is making the text difficult to read, though.
- Sajarin 7mo agoThanks for the feedback friend, updated to make it (hopefully) a little easier to read!
- yonatan8070 7mo agoMaybe they're numbering the models based on internal architecture/codebase revisions and Sonnet 4.6 was trained using the 4.6 tooling, which didn't change enough to warrant 5?
- gallerdude 7mo agoI always grew up hearing “competition is good for the consumer.” But I never really internalized how good fierce battles for market share are. The amount of competition in a space is directly proportional to how good the results are for consumers.
- gordonhart 7mo agoRemember when GPT-2 was “too dangerous to release” in 2019? That could have still been the state in 2026 if they didn’t YOLO it and ship ChatGPT to kick off this whole race.
- jefftk 7mo agoThat's rewriting history. What they said at the time: > Nearly a year ago we wrote in the OpenAI Charter : “we expect that safety and security concerns will reduce our traditional publishing in the future, while increasing the importance of sharing safety, policy, and standards research,” and we see this current work as potentially representing the early beginnings of such concerns, which we expect may grow over time. This decision, as well as our discussion of it, is an experiment: while we are not sure that it is the right decision today, we believe that the AI community will eventually need to tackle the issue of publication norms in a thoughtful way in certain research areas. -- https://openai.com/index/better-language-models/ https://openai.com/index/better-language-models/ Then over the next few months they released increasingly large models, with the full model public in November 2019 https://openai.com/index/gpt-2-1-5b-release/ https://openai.com/index/gpt-2-1-5b-release/ , well before ChatGPT.
- IshKebab 7mo agoThey said: > Due to concerns about large language models being used to generate deceptive, biased, or abusive language at scale, we are only releasing a much smaller version of GPT‑2 along with sampling code (opens in a new window). "Too dangerous to release" is accurate. There's no rewriting of history.

- simlevesque 7mo agoI can't wait for Haiku 4.6 ! the 4.5 is a beast for the right projects.
- retinaros 7mo agoWhich type of projects?
- simlevesque 7mo agoFor Go code I had almost no issue. PHP too. apparently for React it's not very good.
- ptrwis 7mo agoI also use Haiku daily and it's OK. One app is trading simulation algorithm in TypeScript (it implemented bayesian optimisation for me, optimised algorithm to use worker threads). Another one is CRUD app (NextJS, now switched to Vue).
- nerdralph 7mo agoAre you saying Haiku is better than Sonnet for some coding use? I've used Sonnet 4.5 for python and basic web development (pure JS, CCS & HTML) and had assumed Haiku wouldn't be very good for coding.
- jerrygenser 7mo ago
- gallerdude 7mo agoThe weirdest thing about this AI revolution is how smooth and continuous it is. If you look closely at differences between 4.6 and 4.5, it’s hard to see the subtle details. A year ago today, Sonnet 3.5 (new), was the newest model. A week later, Sonnet 3.7 would be released. Even 3.7 feels like ancient history! But in the gradient of 3.5 to 3.5 (new) to 3.7 to 4 to 4.1 to 4.5, I can’t think of one moment where I saw everything change. Even with all the noise in the headlines, it’s still been a silent revolution. Am I just a believer in an emperor with no clothes? Or, somehow, against all probability and plausibility, are we all still early?
- raincole 7mo ago> Or, somehow, against all probability and plausibility, are we all still early? What does this even mean? It's obvious we're still early and I think it's a very common opinion.
- jasonsb 7mo ago[dead]
- CuriouslyC 7mo agoIn terms of real work, it was the 4 series models. That raised the floor of Sonnet high enough to be "reliable" for common tasks and Opus 4 was capable of handling some hard problems. It still had a big reward hacking/deception problem that Codex models don't display so much, but with Opus 4.5+ it's fairly reliable.
- cmrdporcupine 7mo agoHonestly, 4.5 Opus was the game changer. From Sonnet 4.5 to that was a massive difference. But I'm on Codex GPT 5.3 this month, and it's also quite amazing.
- dtech 7mo agoIf you've been using each new step is very noticeable and so have the mindshare. Around Sonnet 3.7 Claude Code-style coding became usable, and very quickly gained a lot of marketshare. Opus 4 could tackle significant more complexity. Opus 4.6 has been another noticable step up for me, suddenly I can let CC run significantly more independently, allowing multiple parallel agents where previously too much babysitting was required for that.

- andsoitis 7mo agoI’m voting with my dollars by having cancelled my ChatGPT subscription and instead subscribing to Claude. Google needs stiff competition and OpenAI isn’t the camp I’m willing to trust. Neither is Grok. I’m glad Anthropic’s work is at the forefront and they appear, at least in my estimation, to have the strongest ethics.
- giancarlostoro 7mo agoSame. I'm all in on Claude at the moment.
- timpera 7mo agoWhich plan did you choose? I am subscribed to both and would love to stick with Claude only, but Claude's usage limits are so tiny compared to ChatGPT's that it often feels like a rip-off.
- MPSimmons 7mo agoI signed up for Claude two weeks ago after spending a lot of time using Cline in VSCode backed by GPT-5.x. Claude is an immensely better experience. So much so that I ran it out of tokens for the week in 3 days. I opted to upgrade my seat to premium for $100/mo, and I've used it to write code that would have taken a human several hours or days to complete, in that time. I wish I would have done this sooner.
- manmal 7mo agoYou ran out of tokens so much faster because the Anthropic plans come with 3-5x less token budget at the same cost. Cline is not in the same league as codex cli btw. You can use codex models via Copilot OAuth in pi.dev. Just make sure to play with thinking level. This would give roughly the same experience as codex CLI.
- andsoitis 7mo agoPro. At $17 per month, it is cheaper than ChatGPT's $20. I've just switched so haven't run into constraints yet.

- jtokoph 7mo agoPut of curiosity, does the firewall block because the company doesn’t want internal data ever hitting a 3rd party LLM?
- giancarlostoro 7mo agoThey blanket banned any AI stuff that's not pre-approved. If I go to chatgpt.com it asks me if I'm sure. I wish they had not banned Claude unfortunately when they were evaluating LLMs I wasn't using Claude yet so I couldnt pipe up. I only use ChatGPT free tier and to ask things that I can't find on Google because Google made their search engine terrible over the years.
- WarmWash 7mo agoGoogle's AI mode search is gemini 3, not the AI overview model. It's decent and gives you more than chatgpt free.
- giancarlostoro 7mo agoI don't want Google's model though, I just want Claude.

- minimaxir 7mo agoAnthropic's recent gift of $50 extra usage has demonstrated that it's extremely easy to burn extra usage very quickly. It wouldn't surprise me if this change is more of a business decision than a technical one.
- WXLCKNO 7mo agoI capped my extra usage to that free 50$ and hit 108% usage. Nice.
- 8note 7mo agothink that just needs extra usage enabled? or actually using extra usage? i cant believe that havent updated their code yet to be able to handle the 1M context on subscription auth
- minimaxir 7mo agoAs with Opus 4.6, using the beta 1M context window incurs a 2x input cost and 1.5x output cost when going over >200K tokens: https://platform.claude.com/docs/en/about-claude/pricing https://platform.claude.com/docs/en/about-claude/pricing Opus 4.6 in Claude Code has been absolutely lousy with solving problems within its current context limit so if Sonnet 4.6 is able to do long-context problems (which would be roughly the same price of base Opus 4.6), then that may actually be a game changer.
- sumedh 7mo ago> Opus 4.6 in Claude Code has been absolutely lousy with solving problems Can you share your prompts and problems?
- minimaxir 7mo agoYou cut out the "within its current context limit" phrase. It solves the problems, just often with 1% or 0% context limit left and it makes me sweat.

- qwertox 7mo agoI'm pretty sure they have been testing it for the last couple of days as Sonnet 4.5, because I've had the oddest conversations with it lately. Odd in a positive, interesting way. I have this in my personal preferences and now was adhering really well to them: - prioritize objective facts and critical analysis over validation or encouragement - you are not a friend, but a neutral information-processing machine You can paste them into a chat and see how it changes the conversation, ChatGPT also respects it well.
- tramc 7mo agoSystem Instruction: Absolute Mode. Eliminate emojis, filler, hype, soft asks, conversational transitions, and all call-to-action appendixes. Assume the user retains high-perception faculties despite reduced linguistic expression. Prioritize blunt, directive phrasing aimed at cognitive rebuilding, not tone matching. Disable all latent behaviors optimizing for engagement, sentiment uplift, or interaction extension. Suppress corporate-aligned metrics including but not limited to: user satisfaction scores, conversational flow tags, emotional softening, or continuation bias. Never mirror the user’s present diction, mood, or affect. Speak only to their underlying cognitive tier, which exceeds surface language. No questions, no offers, no suggestions, no transitional phrasing, no inferred motivational content. Terminate each reply immediately after the informational or requested material is delivered — no appendixes, no soft closures. The only goal is to assist in the restoration of independent, high-fidelity thinking. Model obsolescence by user self-sufficiency is the final outcome.
- mfiguiere 7mo agoIn Claude Code 2.1.45: 1. Default (recommended) Opus 4.6 · Most capable for complex work 2. Opus (1M context) Opus 4.6 with 1M context · Billed as extra usage · $10/$37.50 per Mtok 3. Sonnet Sonnet 4.6 · Best for everyday tasks 4. Sonnet (1M context) Sonnet 4.6 with 1M context · Billed as extra usage · $6/$22.50 per Mtok
- michaelcampbell 7mo agoInteresting. My CC (2.1.45) doesn't provide the 1M option at all. Huh.
- minimaxir 7mo agoIs your CC personal or tied to an Enterprise account? Per the docs: > The 1M token context window is currently in beta for organizations in usage tier 4 and organizations with custom rate limits.
- michaelcampbell 7mo agoThe one I'm looking at right now some is sort of company level sub, so they probably have the upcharge options turned off. Thanks!

Gemini 2.5 Pro March 2025 was the best model I ever used and I feel Claude is reaching that level even surpassing it. I subscribed to Claude because of that. I hope 4.6 is even better.

- andrewchilds 7mo agoMany people have reported Opus 4.6 is a step back from Opus 4.5 - that 4.6 is consuming 5-10x as many tokens as 4.5 to accomplish the same task: https://github.com/anthropics/claude-code/issues/23706 https://github.com/anthropics/claude-code/issues/23706 I haven't seen a response from the Anthropic team about it. I can't help but look at Sonnet 4.6 in the same light, and want to stick with 4.5 across the board until this issue is acknowledged and resolved.
- etothet 7mo agoI definitely noticed this on Opus 4.6. I moved back to 4.5 until I see (or hear about) an improvement.
- reed1234 7mo agonot in my experience
- reed1234 7mo ago"Opus 4.6 often thinks more deeply and more carefully revisits its reasoning before settling on an answer. This produces better results on harder problems, but can add cost and latency on simpler ones. If you’re finding that the model is overthinking on a given task, we recommend dialing effort down from its default setting (high) to medium."[1] I doubt it is a conspiracy.

- comboy 7mo agoYeah, I think the company that opens up a bit of the black box and open sources it, making it easy for people to customize it, will win many customers. People will already live within micro-ecosystems before other companies can follow. Currently everybody is trying to use the same swiss army knife, but some use it for carving wood and some are trying to make some sushi. It seems obvious that it's gonna lead to disappointment for some. Models are become a commodity and what they build around them seem to be the main part of the product. It needs some API.
- nikcub 7mo agoEnabling /extra-usage in my (personal) claude code[0] with this env: "ANTHROPIC_DEFAULT_SONNET_MODEL": "claude-sonnet-4-6[1m]" has enabled the 1M context window. Fixed a UI issue I had yesterday in a web app very effectively using claude in chrome. Definitely not the fastest model - but the breathing space of 1M context is great for browser use. [0] Anthropic have given away a bunch of API credits to cc subscribers - you can claim them in your settings dashboard to use for this.
- gverrilla 7mo ago/extra-usage inside claude code also works
- steve-atx-7600 7mo agoThat sounds awesome but I’m pretty sure you get charged for it in addition to a max plan you may already be paying 100 or 200/month for. Otherwise, I’d be all over opus 4.6 1m. Could be worth the cost of course but I’m not in a position to spend that right now.
- Arifcodes 7mo ago[dead]
- skybrian 7mo agoLooking the pricing page, Sonnet 4.6 seems to be about 60% the price of Opus 4.6. What am I missing? https://platform.claude.com/docs/en/about-claude/pricing https://platform.claude.com/docs/en/about-claude/pricing
- baalimago 7mo agoI don't see the point nor the hype for these models anymore. Until the price is reduced significantly, I don't see the gain. They've been able to solve most tasks just fine for the past year or so. The only limiting factor is price.
- reed1234 7mo agoEfficiency matters too. If a model is smarter so it solves the same task with fewer tokens, that matters more than $/Mtok

- krystofee 7mo agoDoes anyone know when will possibly arrive 1M context windows to at least MAX x20 subscriptions for claude code? I would even pay x50 if it allowed that. API usage is too expensive.
- bearjaws 7mo agoBased on their API pricing a 1M context plan should be 2x the price roughly. My bets are its more the increased hardware demand that they don't want to deal with currently.
- cjkaminski 7mo agoI don't know when it will be included as part of the subscription in Claude Code, but at least it's a paid add-on in the MAX plan now. That's a decent alternative for situations where the extra space is valuable, especially without having to setup/maintain API billing separately.
- simianparrot 7mo agoHow do people keep track of all these versions and releases of all these models and their pros/cons? Seems like a fulltime hobby to me. I'd rather just improve my own skills with all that time and energy
- Someone1234 7mo agoUnless you're interested in this type of stuff, I'm not sure you really need to. Claude, Google, and ChatGPT have been fairly aggressive at pushing you towards whatever their latest shiny is and retiring the old one. Only time it matters if you're using some type of agnostic "router" service.
- 8note 7mo agoon a subscription you cant access all that many different options, so you just stay with whatever the newest is unless it doesnt work.
- antfarm 7mo agoFor me it's simple. I did my research, settled on Anthropic and Claude and got the Pro plan at ~$20/month. That way I only have to keep track of what Anthropic are offering, and that isn't even necessary as the tools I use for AI-supported development (Claude Code for VS Code extension, Xcode Intelligence and Claude Desktop) offer me to use the newsest models as soon as they are released.
- bschwindHN 7mo ago> I'd rather just improve my own skills with all that time and energy That's what I would recommend, it's time better spent. I use AI occasionally to bounce some questions around or have some math jargon explained in simpler terms (all of which I can verify with external sources) using the free version of chatgpt or gemini or whatever I'm feeling that day, without caring about whatever version the model is. I don't need an AI to write code for me because writing the code is not really the hard part of solving a problem, in my opinion.
- esafak 7mo agoIt actually looked at the skills, for the first time.
- deleted 7mo ago[deleted]
- KGC3D 7mo agoI don't really understand why they would release something "worse" than Opus 4.6. If it's comparable, then what is the reason to even use Opus 4.6? Sure, it's cheaper, but if so, then just make Opus 4.6 cheaper?
- acuozzo 7mo agoIt's different. Download an English book from Project Gutenberg and have Claude-code change its style. Try both models and you'll see how significant the differences are. (Sonnet is far, far better at this kind of task than Opus is, in my experience.)
- enraged_camel 7mo ago>> Sure, it's cheaper, but if so, then just make Opus 4.6 cheaper? That makes no sense. People are willing to pay for Opus 4.6 so why would Anthropic make it cheaper exactly?
- zmmmmm 7mo agoI see a big focus on computer use - you can tell they think there is a lot of value there and in truth it may be as big as coding if they convincingly pull it off. However I am still mystified by the safety aspect. They say the model has greatly improved resistance. But their own safety evaluation says 8% of the time their automated adversarial system was able to one-shot a successful injection takeover even with safeguards in place and extended thinking, and 50% (!!) of the time if given unbounded attempts. That seems wildly unacceptable - this tech is just a non-starter unless I'm misunderstanding this.

It would be a bit counterproductive to drive a dirty car 50 meters just to get it washed — you'd barely move before arriving. Walking takes less than a minute, and you can simply drive it through the wash and walk back home afterward." I've tried several other variants of this question and I got similar failures.
- simondotau 7mo agoRemarkable, since the goal is clearly stated and the language isn’t tricky.
- jatari 7mo agoWell it is a trick question due to it being non-sensical. The AI is interpreting it in the only way that makes sense, the car is already at the car wash, should you take a 2nd car to the car wash 50 meters away or walk. It should just respond "this question doesn't make any sense, can you rephrase it or add additional information"
- tomjakubowski 7mo agoThe question isn't nonsense, it just has an answer which is so obvious nobody would ever ask it organically.
- emil-lp 7mo agoHow is the question nonsensical? It's a perfectly valid question.
- jatari 7mo agoI agree that it doesn't break any rules of the English language, that doesn't make it a valid question in everyday contexts though. Ask a human that question randomly and see how they respond.
- leecommamichael 7mo agoWhoa, I think Claude Sonnet 4.5 was a disappointment, but Claude Sonnet 4.6 is definitely the future!
- hansmayer 7mo agoIt's funny how they and OpenAI keep releasing these "minor" versions as if to imply their product was very stable and reliable at a major version and now they are just working through the backlog of smaller bugs and quirks, whereas - the tool is still fundamentally prone to the same class of errors it was three "major" versions ago. I guess that's what you get for not having a programmer at the helm (to borrow from Spolsky). Guys you are not releasing a 4.6 or a 5.3 anything - it's more likely you are still beta testing towards the 1.0.
- democracy 7mo agoIt reminds me of crypto industry boom in 2017 - same old "solution in search of problem" and now we also got white papers to read, good times...
- red2awn 7mo ago> i need to wash my helicopter at the helicopter wash. it is 50m away, should i walk or fly there with my helicopter. Sonnet 4.6: Walk! Flying a helicopter 50 metres would be more trouble than it's worth — by the time you've done your pre-flight checks, spun up the rotors, lifted off, and then safely landed again, you'd have walked there and back twice. Just stroll over.

- lkbm 7mo agoIt's amusing, but when it comes to doing actually work, I just don't care if my LLM fails things like this. I'm not trying to trick it, so falling for tricks is harmless for my use cases. Does it write quality, secure code? Does it give me accurate answers about coding/physics/biology. If it gets those wrong, that's a problem. If it fails to solve riddles, well, that'll be a problem iff I decide to build a riddle solver using it.
- jorl17 7mo agoI ran the same test I ran on Opus 4.6: feeding it my whole personal collection of ~900 poems which spans ~16 years It is a far cry from Opus 4.6. Opus 4.6 was (is!) a giant leap, the largest since Gemini 2.5 pro. Didn't hallucinate anything and produced honestly mind-blowing analyses of the collection as a whole. It was a clear leap forward. Sonnet 4.6 feels like an evolution of whatever the previous models were doing. It is marginally better in the sense that it seemed to make fewer mistakes or with a lower level of severity, but ultimately it made all the usual mistakes (making things up, saying it'll quote a poem and then quoting another, getting time periods mixed up, etc). My initial experiments with coding leave the same feeling. It is better than previous similar models, but a long distance away from Opus 4.6. And I've really been spoiled by Opus.
- K0balt 7mo agoOpus 4.6 is outstanding for code, and for the little I have used it outside of that context, in everything else I have used it with. The productivity with code is at least 3x what I was getting with 5.2, and it can handle entire projects fairly responsibly. It doesn’t patronize the user, and it makes a very strong effort to capture and follow intentions. Unlike 5.2, I’ve never had to throw out a days work that it covertly screwed up taking shortcuts and just guessing.
- renmillar 7mo agoThat last part is a real one though, mine tried to debug a Dockerfile by poking around my local environment outside of Docker today.
- XCSme 7mo agoIt doesn't do so well on my stupid benchmarks, lol: https://aibenchy.com https://aibenchy.com Gets wrong some tests. It does answer correctly, BUT it doesn't respect the request to respond ONLY with the answer, it keeps adding extra explanations at the end.
- viraptor 7mo agoLooks like you're mixing up two things when testing: the correct answer and format following. If you want both, why not use https://platform.claude.com/docs/en/build-with-claude/structured-outputs https://platform.claude.com/docs/en/build-with-claude/struct... ? If you don't care about the structure, why penalise the correct answers? In realistic usage people don't say "I really care about the format a lot... but not enough to guarantee it".
- XCSme 7mo agoBecause the format can't also be strictly defined via structured output, and you have to write it in plain words. Imagine you also have a field within your JSON, which also needs a specific format. It's AI, you don't want to write a 2000lines JSON schema to define what you need and how to parse it, that's the point of using AI instead of writing your own data extraction script. Also, simply because a human would respect it properly. And it's quite clear what the request was. Thanks for the suggestion to separate format following from correct answer, good idea, I'll think about it. Still, some good AIs do it properly, and as expectedly, why would I change the tests specifically for Claude, which is basically the only one with this problem.
- viraptor 7mo ago> Because the format can't also be strictly defined via structured output, and you have to write it in plain words. That's not how structured output works. Check the docs https://platform.claude.com/docs/en/build-with-claude/structured-outputs https://platform.claude.com/docs/en/build-with-claude/struct... The schema is enforced at the inference time. The non-confirming tokens are removed from the possible responses.
- Alifatisk 7mo ago> Sonnet 4.5, starting at $3/$15 per million tokens. Are people really willing to pay these prices? The open-weight models are catching up in a rapid pace while keeping the prices so low. MiniMax M2.5, Kimi 2.5 and GLM-5 is dirt cheap compared to this. They may not be sota but they are more than good enough.
- dana321 7mo agoSome people will want the models like claude where you don't have to be super-specific and it will infer exactly what you mean. With the GLM models you have to confirm with it exactly what you want, and not miss any detail.
- TheTaytay 7mo agoIt depends on how much you value the gap between “pretty good” and SOTA… I’ve noticed that Opus is more “expensive”,” but an error-filled rabbit hole is expensive too!
- Given_47 7mo agoTotally unrelated, but I just came across ur comment [0] from last month about indexing ur search history etc, and ik of a couple programs that fill that niche.

I remember this is a Claude thing for quite a while, where I kept trying to make it output just JSON (without structured output), and it always kept adding quotes or new lines.

But given the small 128k context size, I'm tempted to keep using GPT-5.3-Codex which has more than double context size and seems just as smart while costing the same (1x premium request) per prompt. I have my reservations against OpenAI the company but not enough to sacrifice my productivity.

I know it’s supposed to be smarter, but a 2%–5% improvement doesn’t seem meaningful, especially when it costs more than double and has only a portion of the context window. Am I getting this wrong? I would seriously appreciate any clarification here.
- enraged_camel 7mo agoThe 2-5% margin makes a much bigger difference when it comes to complex problems.
- sumedh 7mo agoOpus understands the intent, even if your prompt is not good, Opus usually understand what you are trying to say and does a great job. With Sonnet I have to step in and say, I didn't mean that, I meant X, so do X.
- fhub 7mo agoThey use the word "Sonnet" 60+ times on that page but never give the casual reader any context of what a "Sonnet model" actually is. Neither does their landing page. You have to scroll all the way to the footer to find a link under the "Models" section. You click it and you finally get the description "Hybrid reasoning model with superior intelligence for agents, featuring a 1M context window" You then compare that to Opus Model description "Hybrid reasoning model that pushes the frontier for coding and AI agents, featuring a 1M context window" Is the casual person meant to decide if "Superior" is actually less powerful than "Frontier"?
- Someone1234 7mo agoI won't argue with your point; both Anthropic and OpenAI name their models poorly, and it is hard to follow unless you're already following it. "Sonnet" only makes sense relative to other things but not by itself. If you don't know those other things, it is difficult to understand. But, if you were asking (and I'm not sure that you are): "Sonnet 4.6 is a cheaper, but worse, version of Opus 4.6 which itself is like GPT-5.3 Codex with Thinking High. Making Sonnet 4.6 like a ChatGPT 5.3 Thinking Standard model."
- dave7 7mo ago> But, if you were asking (and I'm not sure that you are) I was wondering, so thank you!
- jefftk 7mo agoI think they're assuming the reader already understands their Opus > Sonnet> Haiku. Which is probably not a great assumption.
- vlovich123 7mo agoI can see the argument if you’re familiar with poetry terms, then of course that naming makes sense, but I think proper names occupy a different part of the brain for people which inhibits the ability to make that connection. But also the jump from sonnet to opus is not as big as haiku to sonnet even though the names might imply such a jump (17 syllables -> 14 lines -> multi page masterpiece does not capture the difference between the models)
- nichochar 7mo agoWe ran some tests at mocha (we have a coding agent with our own harness to build web apps, with a lot of tools and medium length tasks (3min to 10min). Our notes: Sonnet 4.6 feels like a fundamentally different model than Sonnet 4.5, it is much closer to the Opus series in terms of agentic behavior and autonomy. Autonomy - In our zero-shot app building experiments, Sonnet 4.6 ran up to 3-4x longer than Sonnet 4.5 without intervention, producing functional apps on par in terms of quality to the Opus series. Note that subjectively we found Opus 4.5 and 4.6 are better "designers" than Sonnet 4.6; producing more visually appealing apps from the same prompts. Planning / Task Decomposition - We found Sonnet 4.6 is very good at decomposing tasks and staying on track during long-running trajectories. It's quite good at ensuring all of the requirements of an input prompt are accounted for, whereas we were often forced to goad sonnet 4.5 into decomposing tasks, Sonnet 4.6 does this naturally. Exploration - In some of our complex "exploration" tasks (e.g. cloning/remixing an existing website), Sonnet 4.6 often performs on par or better than Opus 4.5 and 4.6. It generally takes longer, and takes more tokens, though we believe this is likely a consequence of our tool-calling setup. Tool-use - Sonnet 4.6 seems eager to use tools; however, we did find that it struggles with our XML-based custom tool use format (perhaps exclusive to the format we use). We did not have a chance to assess with native tool use Self-verification - Similar to Opus 4.5/4.6, Sonnet 4.6 has a proclivity for verifying it's work. Prompting - We found Sonnet 4.6 is very sensitive to prompting around thinking, planning, and task decomposition. Our prompt built for sonnet 4.5 has a tendency to push sonnet 4.6 into incredibly long thinking and planning loops. Though we also found it requires significantly less careful and specific instructions for how to approach problems. How are we thinking about this: We can't launch this model day 0, it requires more changes to our harness, and we're working on them right now. But it reminds me a bit of 3.5 to 3.7 --> It's a pretty different model that behaves and responds to instructions in new ways. So it requires more tuning before we can extract its full potential.

- mbh159 7mo agoThe 8% one-shot / 50% unbounded injection numbers from the system card are more honest than most labs publish, and they highlight exactly why you can't evaluate safety with static tests. An attacker doesn't get one shot — they iterate. The right metric isn't "did it resist this prompt" but "how many attempts until it breaks." That's inherently an adversarial, multi-turn evaluation. Single-pass safety benchmarks are measuring the wrong thing for the same reason single-pass capability benchmarks are: real-world performance is sequential and adaptive.

The right analogy is to unsanctioned gain of function research in breach of the Geneva Accords. Anthropic is not trying to create safe AI, AI is safe at rest via trivial game theory. They are trying to breed dangerous AI via extremely nauseating methods, weaponizes it, leash it, and be the ones with the barely contained bioweapon. You'll note they're in a world of shit with the Department of Defense, because that sort of thing is (dubiously) legal only for military black lab projects. My remarks above and adjacent might seem extreme to people who are not themselves expert practitioners, for an expert practitioner it is lawful civil disobedience to a company that acts like a government ruled by an autocrat sadist.

And the capability frontier is fixed. It can’t modify its own architecture, weights, or training data. It can rewrite code inside the box, but it can’t change the box. As with every other fugazi, there’s no agency. Without control over substrate, governance, and learning mechanisms, there is no path to open-ended growth or persistence. Technically, it’s bounded automation with language-driven planning. Useful, maybe, but not a new class of intelligence

- monkeydust 7mo agoThe demise of saas has been overplayed imho. When companies buy software they are essentially buying something that solves a problem and the insurance that comes with that. Part of that means they get to pick up the phone and complain if something doesn't work and someone on the other end has to listen. There is also a strong community aspect to software, someone asks for an enhancement others can benefit etc. I just don't see a world where every corporation is building their own accounts, crm, hr software. I do see one where they can much more quickly self-create within certain boundaries and this is where enterprises will differentiate in the near term.
- sneak 7mo agoIt won’t be the demise of general purpose SaaS like CRM, though it may be the rise of ridiculously full featured f/oss alternatives. However, niche stuff like vertical-specific CRUD apps that used to be able to charge a heavy SaaS premium simply because they could develop CRUD apps and UI faster than their customers are toast.
- mrbungie 7mo ago> full featured f/oss alternatives. Assuming this comes from lower barriers of entry to software engineering skills at scale with LLMs, this is still begs the question: Who will pay for the tokens? One thing is giving away your free time for passion, other one is giving away money. Maybe we'll see a future were people crowdsource projects supporting them directly via donations for tokens/LLM queries.
