Configuration
In~/.codex/config.toml:
Models
Use Codex-tuned ids such asgpt-5.3-codex or any supported OpenAI-compatible
model from Models.
wire_api = "responses" is the current Codex CLI shape for custom providers.
If you keep an older wire_api = "chat" provider block, update it before
testing OmniaKey.
