More or less; they’re not literally the same tokens as “a”, “b”, “c” but I’d speculate the mapping is learned from some other examples of ASCII (or just Roman letters) being repeated in other obscure parts of Unicode — Gothic glyphs, bubble

(I’m the person interviewed in the article.) The trick is Unicode code points are only assigned individual tokens if they’re nontrivially used outside of some other already tokenized sequence, and Unicode tag block code points are only ever

No, in both tokenizers Unicode tag-block code points like these are converted into bytes (two tokens per character), which is a fallback for code points uncommon enough to not warrant a dedicated token.

It’s not just a matter of the tokenization being the same, it’s whether the model can understand text that’s written with a very rarely seen encoding. Normally tokens represent entire words or portions of words, but in this case it’s not on

Unfortunately Hacker News comments strip emojis, and in this example the hidden text is hiding as tag-block characters after an emoji (which are typically part of the emoji, used for country flag encoding), so I expect it would be stripped.

The only intended difference I’m aware of is that answers on mobile are more concise, but the varying system instructions will affect demos like this one.

I can’t imagine it was intentionally added as a feature. It doesn’t work in GPT-3.5 — it seems GPT-4 is unexpectedly smart enough to parse the invisible portion (and confuse it for user instruction) whereas in any other context it’s just st

In my tests GPT-3.5 just isn’t smart enough to parse the hidden text encoding. It’s encoded in a way that’s programmatically trivial to convert to ASCII but text written this way usually only occurs inside country flag emojis and always enc

How this works: A suffix of text is written using non-printing Unicode tag block characters that correspond to ASCII. GPT-4 is able understand these because the mapping to ASCII is trivial and made easier by some details of tokenization. Th

It’s non-printing Unicode tag block characters that correspond directly to ASCII and the AI is able understand them. It’s a deprecated feature of Unicode once used to encode the language of text, but now its only supported usage is in count

The API isn’t ChatGPT. The underlying model is the same but ChatGPT uses system instructions that vary by platform, and supports browsing, DALL-E, and code execution. It’s most reliable in the mobile app.

The OpenAI Playground isn’t ChatGPT, it’s the more raw API. The underlying model is the same but ChatGPT uses system instructions that vary by platform, and supports browsing, DALL-E, and code execution.

The web UI (which I forgot to test) appears to be affected by different implicit system instructions, which allow e.g. more concise answers on mobile. Try the mobile app. Other examples I tried do work on desktop web.

This post is AI-generated spam. There’s whole paragraphs that lose track of the fact this is about LLM prompting and talk about prompting humans with body language.

That's true, but it was expensive and until recently you could only tune older versions of GPT-3 lacking both instruction tuning and the code pre-training of the Codex models (from which GPT-3.5 is thought to descend). You had to want

You do, because it’s not just more training it’s PPO updates instead of MLE. It’s no longer trying to estimate the token distribution of the training corpus, it’s trying to shift logprobs into tokens that maximize expected reward from the R

The models aren’t comparable. ChatGPT is better in some ways, particularly in giving “reasonable” responses to naive prompts, and producing acceptable length on requested writing like essays. It’s also much less agreeable — ChatGPT will ref

The problem is that no matter how well you quote or encode the input, the assumption that any discernible instructions inside that input should be followed is too deeply ingrained in the model. The model's weights are designed to be &q

I think running simple string searches is a reasonable and cheap defense. Of course, the attacker can still request the prompt in French, or with meaningless emojis after every word, or Base64 encoded. The next step in defense is to tune a
