don’t expect sol to blow you away in the same way fable did. but expect something close with a lot more usage. and expect more to come from the lab that has the mandate back
I had early access to GPT-5.6 Sol.
It’s an amazing model, but for almost every task I tested, Fable was quite a bit better, and more agentic to boot (one Fable turn does the same thing many 5.6 turns do).
Full review coming on launch day!
Don’t get me wrong, this model is a huge jump over 5.5.
Fable just has the feel of a much bigger model that I can trust a good bit more!
I expect OpenAI will have an answer to Fable soon.
i’ve been using sol for two months so i’ll write a longer post later but it’s basically a hair below fable for intelligence, has slightly worse design taste.
but you’ll be able to use it a hell of a lot more and it’s a lot better for longer horizon agentic work. far more…
EM had early access to GPT-5.6. A different feel is good, model diversity is good. I think it's a better future if they all grow apart and become more distinctive from here on out. https://twitter.com/emollick/status/2074712677755035907
