# NousResearch/hermes-agent · Codex image gen host model hardcoding fixes

## Open now

- Nothing open on GitHub.

Multiple fixes addressing a hardcoded chat model (gpt-5.5) used to host Codex image generation, which broke for accounts without access to that model. Changes make the host model configurable, follow the active chat model, or use native image endpoints instead.
