💡 Codex Review

Lines 452 to 454 in ecc4440
xhigh palette option saved as off
The command palette now exposes an xhigh thinking level (mapped over THINKING_LEVELS here), but App.tsx still normalizes palette submissions against a four-value THINKING_LEVELS = ["off","low","medium","high"] when persisting (setThinkingLevelFromPalette around lines 44/300). Selecting xhigh for any model therefore gets coerced to "off" before it reaches the thinking provider, so the newly added level can’t actually be used.

Gonna finish this off as I assume you're out for the weekend |
Add support for OpenAI's gpt-5.1-codex-max model which introduces a new 'xhigh' (Extra High) reasoning effort level for extended deep thinking. Changes: - Extended ThinkingLevel type to include 'xhigh' as 5th option - Added GPT_CODEX_MAX to known models with codex-max alias - Updated thinking policy to return 5 levels for codex-max only - Added xhigh to UI level descriptions and command palette - Added model pricing/capability data to models-extra - Updated SendMessageOptionsSchema to accept xhigh - Added comprehensive tests for codex-max policy The xhigh level is exclusive to gpt-5.1-codex-max. Other models gracefully fall back to their maximum supported level when xhigh is requested. Change-Id: Iab7ba7187703e275c4c0aa76779381dff4006316 Signed-off-by: Thomas Kosiewski <tk@coder.com>
Same pricing as gpt-5.1-codex: $1.25/M input, $10/M output Also aligned max token limits with the codex model. Change-Id: I030014df05a5ccae62f5c93d7435ec2363d23317 Signed-off-by: Thomas Kosiewski <tk@coder.com>
