People use Jev to pick a model before a task. I made it change GPT-6's reasoning effort inside Codex DURING the task. More thinking when stuck. Less for routine steps. 50% lower Astra costs in my tests. Faster runs, without breaking prompt caching. https://t.co/NrpGFfWW9v

Jev uses more reasoning when the task is stuck and less for routine steps. vechen says the approach preserves prompt caching and makes runs faster.
