The Opus model that seems to perform better than GPT4 is unfortunately much more expensive than the OpenAI model. Pricing (input/output per million tokens): GPT4-turbo: $10/$30 Claude 3 Opus: $15/$75

Their smallest model outperforms GPT-4 on Code. I'm sceptical that it'll hold up to real world use though.

Yeah the output pricing I think is really interesting, 150% more expensive input tokens 250% more expensive output tokens, I wonder what's behind that? That suggests the inference time is more expensive then the memory needed to load it in the first place I guess?

Either something like that or just because the model's output is basically the best you can get and they utilize their market position.

Probably that and what you mentioned.

There’s a market for that though. If I am running a startup to generate video meeting summaries, the price of the models might matter a lot, because I can only charge so much for this service. On the other hand, if I’m selling a tool to have AI look for discrepancies in mergers and acquisitions contracts, the difference between $1 and $5 is immaterial… I’d be happy to pay 5x more for software that is 10% better because the numbers are so low to begin with.

My point is that there’s plenty of room for high priced but only slightly better models.

I hate that they require a phone number but this might be the only way to prevent abuse so I'll have to bite the bullet. > We’ve made meaningful progress in this area: Opus, Sonnet, and Haiku are significantly less likely to refuse to answer prompts that border on the system’s guardrails than previous generations of models. Finally someone who takes this into account, Gemini and chatGPT is such an obstacle sometimes…

I think it's just to get free credits that you need to give a phone number?

To the other point, yes it's crazy that "When inside kitty, how do I get my python inside latex injected into Julia? (It somehow works using alacritty?)" Despite the question being pretty underspecified or confusing, it still shouldn't read as inappropriate.

Unfortunately, many image generation systems will refuse prompts with latex in them (I assumed it was a useful term for styling).

My best guess is that it thinks latex is more often used as a clothing item or something, and it's generally associated with inappropriate content. Just unfortunate for scientists :/.

I don't put a lot of stock on evals. many of the models claiming gpt-4 like benchmark scores feel a lot worse for any of my use-cases. Anyone got any sample output? Claude isn't available in EU yet, else i'd try it myself. :(

I think aws has Claude in Frankfurt not the new one but instant and 2 should be there.

That's quite expensive indeed. At full context of 200K, that would be at least $3 per use. I would hate it if I receive a refusal as answer at that rate.

cost is relative. how much would it cost for a human to read and give you an answer for 200k tokens? Probably much more than $3.

Earlier quoted context omitted.

How would that work technically, from a cost of goods sold perspective? (honestly asking, curious)

I think the answer's in the original question: the provider has to pay for extra storage to cache the model state at the prompt you're asking to snapshot. But it's not necessarily a net increase in costs for the provider, because in exchange for doing so they (as well as you) are getting to avoid many expensive inference rounds.

Isn't the expensive part keeping the tokenized input in memory?

Does any of those LLM-as-a-service companies provide a mechanism to "save" a given input? Paying only for the state storage and the extra input when continuing the completion from the snapshot? Indeed, at 1M token and $15/M tokens, we are talking of $10+ API calls (per call) when maxing out the LLM capacity. I see plenty of use cases for such a big context, but re-paying, at every API call, to re-submit the exact sam…

The "cost" is storing the state of the LLM after processing the input. My back-of-the-envelop guesstimate gives me 1GB to capture the 8bit state of 70B parameters model (I might be wrong though, insights are welcome), which is quite manageable with NVMe storage for fast reload. The operator would charge per pay per "saved" prompt, plus maybe a fix per call fee to re-load the state.

At this point I wonder how much of the GPT-4 advantage has been OpenAI's pre-training data advantage vs. fundamental advancements in theory or engineering. Has OpenAI mastered deep nuances others are missing? Or is their data set large enough that most test-cases are already a sub-set of their pre-training data?

More than pretraining data, I think the advantage was ChatGPT and how quickly it grew. Remember it was 3.5, and within a month or two, it generated so many actual q&a pairs with rating, feedback, and production level data of how a model will be used by actual users. Those queries and subsequent RLHF + generating better answers for the questions meant the model would have been improved a lot at the SFT stage. Think th…

My understanding is that GPT-4 had been almost fully trained before ChatGPT was released - they spent around six months testing GPT-4 before making it available to the public, ChatGPT came out 31st November 2022, GPT-4 came out March 14th 2023.

But maybe that was still enough time for them to instruction tune it based on ChatGPT feedback, or at least to focus more of their fine tuning iteration in the areas they learned were strong or weak for 3.5 based on ChatGPT usage?
