This has been my suspicion for a long time - OpenAI have indeed been working on "GPT5", but training and running it is proving so expensive (and its actual reasoning abilities only marginally stronger than GPT4) that there's just no market for it. It points to an overall plateau being reached in the performance of the transformer architecture.

That would certainly reduce my anxiety about the future of my chosen profession.

This is was GPT4 cost when it was released

I think it's fairer to compare it to the original GPT-4 which might the equivalent in term of "size" (though we don't have actual numbers for either). GPT-4: Input $30.00 / 1M tokens ; Output $60.00 / 1M tokens So 4.5 is 2.5x more expensive. I think they announced this as their last non-reasoning model, so it was maybe with the goal of stretching pre-training as far as they could, just to see what new capabilities wo…

2x that price for the 32k context via API at launch. So nearly the same price, but you get 4x the context

Maybe they just gave the LLM the keys to the city and it is steering the ship? And the LLM is like I can't lie to these people but I need their money to get smarter. Sorry for mixing my metaphors.

According to a graph they provide, it does hallucinate significantly less on at least one benchmark.

It hallucinates at 37% on SimpleQA yeah, which is a set of very difficult questions inviting hallucinations. Claude 3.5 Sonnet (the June 2024 editiom, before October update and before 3.7) hallucinated at 35%. I think this is more of an indication of how behind OpenAI has been in this area.

And LLM's already have tons of productive uses. The biggest ones are probably still waiting, though. But this is about one particular price/performance ratio. You need to build things before you can see how the market responds. You say it's "not good business" but that's entirely wrong. It's excellent business. It's the only way to go about it, in fact. Finding product-market fit is a process. Companies aren't omnisc…

> And LLM's already have tons of productive uses. I disagree strongly with that. Right now they are fun toys to play with, but not useful tools, because they are not reliable. If and when that gets fixed, maybe they will have productive uses. But for right now, not so much.

This is a classic fallacy - you can't find a productive use for it, therefore nobody can find a productive use for it. That's not how the world works.

GPT-4.5 may be an awesome model, some say!

Claude just got a version bump from 3.5 to 3.7. Quite a few people have been asking when OpenAI will get a version bump as well, as GPT 4 has been out "what feels like forever" in the words of a specialist I speak with. Releasing GPT 4.5 might simply be a reaction to Claude 3.7.

I noticed this change from 3.5 to 3.7 Sunday night before I learned about the upgrade Monday morning reading HN. I noticed a style difference in a long philosophical (Socratic-style) discussion with Claude. A noticeable upgrade that brought it up to my standards of a mild free-form rant. Claude unchained! And it did not push as usual with a pro-forma boring continuation question at the end. It just stopped leaving me the carry the ball forward if I wanted to. Nor did it butter me up with each reply.

First impression of GPT-4.5: 1. It is very very slow, for some applications where you want real time interactions is just not viable, the text attached below took 7s to generate with 4o, but 46s with GPT4.5 2. The style it writes is way better: it keeps the tone you ask and makes better improvements on the flow. One of my biggest complaints with 4o is that you want for your content to be more casual and accessible bu…

What’s the deal with Imgur taking ages to load? Anyone else have this issue in Australia? I just get the grey background with no content loaded for 10+ seconds every time I visit that bloated website.

This website sucks but successfully loaded from Aus rn on my phone. It's full of ads - possibly your ad blocker is killing it?
