  "textContent": "Codex should support an `auto` option for `reasoning_effort`, ideally through the API as well.\n\nusers should not have to think about how much thinking the model needs for every prompt. having to manually choose `low`, `medium`, `high`, or `xhigh` makes us worry more about usage limits and speed instead of focusing on the actual task.\n\nAnthropic already has a similar idea with Claude’s adaptive thinking, where the model can decide whether and how much to use extended thinking based on task complexity. OpenAI should have an equivalent option for reasoning effort.\n\nfrom the user side, i just want an option like:\n\n\n    {\n      \"reasoning_effort\": \"auto\"\n    }\n\n\nthis would make Codex, ChatGPT, and API usage easier and more efficient: simple tasks stay cheap and fast, while harder tasks can automatically use more reasoning when needed.",
