[premg16]

Prerequisites

• I will write this issue in English (see our Language Policy)

• I have read the documentation or asked an AI coding agent with this project's GitHub URL loaded and couldn't find the answer

Bug Description

I configured my config with gpt-5.2-codex but when i start opencode, it rewrites the config to gpt-5.3-codex.
I use openai api keys, gpt-5.3-codex is not available yet in the api.
It is annoying that I have to change the model eveytime i create new session.

Steps to Reproduce

1. Configure oh-my-opencode.json with gpt-5.2-codex
2. Run opencode
3. Automatically rewrites config to gpt-5.3-codex.

Expected Behavior

I just want the opencode to use the model that i defined in config.

Actual Behavior

It changes the model in the config to gpt-5.3-codex
