They do heavily use AI, but you haven’t refuted their point that if inventory is in SQL, storing reservation in a second storage system increases complexity.

Yes, this is a great point and it’s even one that the Cerebras CEO spruiks for his own chips. Talaas has gone furthest on the spectrum here, so seems to have the most potential to evolve the use cases.

Taalas is developing this, but not for Frontier class models. I hope that if we can least get the easy 80% of work done on that sort of hardware, we can greatly reduce the demand for GPUs, HBM and energy to some extent.

They’re not using ciphertext in inference. They are encrypting agent responses on their servers if it’s going to a subagent on the client. The subagent will send it back to their servers for inference. Only their servers have the keys, so

Yeah, if user -> org tenancy is stored in the same database without any similar defence in depth then a fresh API key after updating org would work around this. Would be a interesting topic for them to cover. I think the same HMAC(peppe

The OPs point wasn’t that OpenAis financial situation is comparable to Apples. It was that the likely cost of litigation is a drop in the ocean for OpenAi too despite their comparative lack of cash to burn. Legal disputes like this cost in

That’s what they do, but the TPM pepper is also needed for HMACing in their threat model. Otherwise the attacker just adds the victim’s user id to their hashing process too.

Zero data retention was an enterprise agreement that Anthropic and Amazon agreed with customers and delivered on. There’s no way AWS would trade in their reputation with enterprises just to soak up some slop.

I’ve seen whole teams at companies set up fail to provide these booleans-as-a-service well. There are whole companies like LaunchDarkly for them. If you boil it down to this, you may as well boil down every service that exists to bits-as-

At least Anthropic claims that they are profitable on a per model basis. But since both revenue and training costs are growing exponentially, and they need to pay for model N training today, and only get revenue for model N-1 today, the off

Yes, but it’s a common misconception that impact is a bad thing. The body, including bones, muscles, tendons and joints, adapt to stress. Many people do too little, not too much, as they get older. There’s a limit to that recovery of cours

I also think fsync before acking writes is a better default. That aside, if you were to choose async for batching writes, their default value surprises me. 2 minutes seems like an eternity. Would you not get very good batching for througho

Yes, the greenest browser is one that doesn’t use AI. They aren’t claiming they’ve built that though, just the greenest AI.

It’s interesting that the author chose to use SHA256 hashing for the CPU intensive workload. Given they run on hardware acceleration using AES NI, I wonder how generally applicable it is. Still interesting either way though, especially si

Yeah, investing in the top companies leads to higher returns for most periods when looking short term. Over longer periods, the top companies by market cap tend to change though. https://www.investmentnews.com/equities&#x2F

Runtimes with garbage collectors typically optimize for allocation, not deletion.

While they don’t specify it sounds like they don’t even require 2FA to access their systems?

Tangential to the authors point, but it’s funny to note many new SQL databases(e.g CockroachDB, TiDB, MyRocks) are written on top of RocksDB, a “NoSQL” key value store.

When it comes to cache invalidation worse performance isn’t the primary concern in most cases, correctness is.

It’s usually a safe bet that the state will preference companies over both employees and taxation unfortunately.

I think this architecture would be really powerful paired with the actor model to shard databases to nodes.

At big tech companies I’ve seen and heard about, the answer is crypto shredding. Encrypt all PII at rest with a per user data key. GDPR deletion requests can then delete the data key. This isn’t perfect, but it’s a step in the right dire

For anyone else expecting this to be a paper given the domain name, it’s not. It’s a non technical interview with a couple of the original papers authors. Not bad, just not as exciting as I imagine a paper detailing what they’ve learnt from

This would be an interesting article to flesh out. I.e is there evidence that MySQL is more reliable in those ways? I always prefer reliability over features even though I’m a product engineer so if he’s right it’d be good to know. Either

I think there’s a good argument that async is decent for performance critical languages, e.g C++ and Rust, and for languages looking to model effects, e.g Haskell and arguably Rust. I don’t see a good reason for it in mainstream languages

It was very clear from their post that they were criticising STS from the perspective of an engineer in AWS within a different team.
