GPT-5 ought to come around September 20, 2028, but Altman said today it’ll be out within months
I don’t think what he said meant what you think it meant. Exact words:
In both ChatGPT and our API, we will release GPT-5 as a system that integrates a lot of our technology, including o3
The “GPT-5” he’s talking about is not the next generation of GPT-4, not an even bigger pretrained LLM. It is some wrapper over GPT-4.5/Orion, their reasoning models, and their agent models. My interpretation is that “GPT-5″ the product and GPT-5 the hypothetical 100x-bigger GPT model, are two completely different things.
I assume they’re doing these naming shenanigans specifically to confuse people and create the illusion of continued rapid progress. This “GPT-5” is probably going to look pretty impressive, especially to people in the free tier, who’ve only been familiar with e. g. GPT-4o so far.
Anyway, I think the actual reason the proper GPT-5 – that is, an LLM 100+ times as big as GPT-4 – isn’t out yet is because the datacenters powerful enough to train it are only just now coming online. It’ll probably be produced in 2026.
in gpt5, are gpt* and o* still separate models under the hood and you are making a model router? or are they going to be unified in some more substantive way?

It’s unclear exactly what the product GPT-5 will be, but according to OpenAI’s Chief Product Officer today it’s not merely a router between GPT-4.5/o3.
Fair enough, I suppose calling it an outright wrapper was an oversimplification. It still basically sounds like just the sum of the current offerings.
