Separate model selection for Plan vs Execute modes (e.g., GPT-5-high for planning + GPT-5-Codex execute)
Resolved 💬 4 comments Opened Oct 23, 2025 by proxlavee Closed Dec 31, 2025
What feature would you like to see?
Allow Codex to use one model for planning and a different one for execution. Example: use a gpt5-high to outline a solution, then switch to a gpt5-codex to implement.
Note : i know plan mode does not exist yet.
