GPT-6.1 Sol arrives just 7 days after GPT-6 Sol, nearly matching Astra at a quarter of the cost
GPT-6.1 Sol replaces GPT-6 Sol after just 7 days, with near-Astra intelligence
GPT-6.1 Sol lands one point below GPT-6 Astra on the Intelligence Index while costing less than a quarter per task ($0.72 vs $3.26). It gains 4 points over GPT-6 Sol and 5 over GPT-5.6 Sol, with notable jumps in Terminal-Bench 4.0 (+12), Humanity's Last Exam (+5), and AA-Omniscience Accuracy (+8), while hallucination rate falls from 60% to 54%. Pricing stays at $2/$10 per million tokens, but the cache read discount rises to 95%.
All effort levels of GPT-6.1 Sol push out the cost efficiency Pareto frontier: for a given level of intelligence, there is no cheaper model.

I would just LOVE to see all the behind-the-scenes shithousery both companies are employing to one-up the other in this, largely, 2-horse AGI race. Someone should make a mockumentary when all is said and done!

What do people get out of being so reductionist?
Every time a new model comes out, people come out in droves "oh I don't notice anything different".
People have been saying this about <currentModel-1> for 2 years now, and the entire state of AI has changed dramatically.
It cannot be that the next AI model isn't better, but also suddenly what they are capable of is on an entirely different level.

I suspect google has a model that is at the same level but is waiting strategically to release rather than this constant week to week dash.
Still seems to me like google is in a good position with AI just based on their size and approach.

Worries of AI going rogue take so much attention that no governance body seems to care about the shady subscriptions and limits business.

After 5.5, I basically don't notice a jump in model performance, other than my usage ending sooner.
