Moving From GPT-5.6 Sol to GPT-6 Astra: Set It to Medium and Walk Away
Nobody has asked me whether GPT-6 Astra is better than Sol. Everyone has asked me what to set the reasoning effort to. OpenAI’s docs list five levels, tell you none of them is the default any more, and leave it there. The Codex crowd say high. A few people on X say max because you’re paying flagship money anyway so why not. One person on dev.to did the maths and landed on medium.
