#62One thing that Altman does extremely well is to over-promise and under-deliver.
Re: GPT-4.5
#63GPT pro already has already rummored to be 100k users. You think GPT 4.5 will add to that even with the insane costs for corporate users?
What rumors? I looked and can’t find something to substantiate that #
Re: GPT-4.5
#64Sounds like it's a distill of O1? After R1, I don't care that much about non-reasoning models anymore. They don't even seem excited about it on the livestream. I want tiny, fast and cheap non-reasoning models I can use in APIs and I want ultra smart reasoning models that I can query a few times a day as an end user (I don't mind if it takes a few minutes while I refill a coffee). Oh, and I want that advanced voice mo…
It isn't even vaguely a distill of o1. The reasoning models are, from what we can tell, relatively small. This model is massive and they probably scaled the parameter count to improve factual knowledge retention.
They also mentioned developing some new techniques for training small models and then incorporating those into the larger model (probably to help scale across datacenters), so I wonder if they are doing a bit of what people think MoE is, but isn't. Pre-train a smaller model, focus it on specific domains, then use that to provide synthetic data for training the larger model on that domain.

#65GPT 4.5 pricing is insane: Price Input: $75.00 / 1M tokens Cached input: $37.50 / 1M tokens Output: $150.00 / 1M tokens GPT 4o pricing for comparison: Price Input: $2.50 / 1M tokens Cached input: $1.25 / 1M tokens Output: $10.00 / 1M tokens It sounds like it's so expensive and the difference in usefulness is so lacking(?) they're not even gonna keep serving it in the API for long: > GPT‑4.5 is a very large and comput…
I wonder how much money they’re losing on it too even at those prices.
Re: GPT-4.5
#66Finally a scaling wall? This is apparently (based on pricing) using about an order of magnitude more compute, and is only maybe 10% more intelligent. Ideally DeepSeeks optimizations help bring the costs way down, but do any AI researchers want to comment on if this changes the overall shape of the scaling curve?
Re: GPT-4.5
#67Now imagine this model (or an optimized/slightly downsized variant thereof) as a base for a "thinking" one.

You’re at the 200 dollar tier?
Not available in model picker for my pro 200 dollar account.

Re: GPT-4.5
#69Are they saying that 4.5 has a 35% hallucination rate? That chart is a bit confusing.
Re: GPT-4.5
#70Per Altman on X: "we will add tens of thousands of GPUs next week and roll it out to the plus tier then". Meanwhile a month after launch rtx 5000 series is completely unavailable and hardly any restocks and the "launch" consisted of microcenters getting literally tens of cards. Nvidia really has basically abandoned consumers.
