GPT-5.1 Instant and Thinking are trained using the same stack as OpenAI's reasoning models, so they score higher on factuality and complex problem-solving than GPT-5, while also introducing a more natural, conversational tone. We think many people will find that GPT-5.1 does a better job of bringing IQ and EQ together, but one default clearly can’t meet everyone’s needs.
Impressive update! GPT-5.1 feels more consistent in complex instructions. Any plans for exposing more granular control over the Thinking mode in the API?
There is no assistant anymore, apis have no control model can randomly go in thinking mode that can minimum take upto 14 seconds so for getting any llm response should we keep the thread open but that would expose our apis, so what’s the solution?
If one day it creates fundamental knowledge and can prove itself to be correct, how can such issues be regulated?
