Problem
Hey Tibo, thanks for the new context length. The speed for GPT-6.1-Sol in fast-mode is now same as it was in non-fast mode. I used to get 40 to 50 tok/sec until Today. Now it dropped to half. Hope you fix it soon.

Problem
Brother RIGHT NOW AS I TYPE THIS Sol 6.1 in "Fast" mode is STILL DOG SLOW. Can you signal to me you are aware of this Tweet and/or problem? It's the same BS every day now during the working day hours for GMT (8am-5pm) which is the middle of the morning for OpenAI staff. Explain?

Win
gpt-6.1-sol is really slow, I turn on fast mode and it just work like normal speed than before

Mixed
Sol 6.1 medium on fast is just unusable. Extremelly slow. I think open AI could focus on improving this outside fest and outside ultrafast too. Also please, an indicator of tok/s on app and cli wouldn't be bad.
