Hi @sevJoe — yes, it seems we were talking about 2 different things. The “Explore subagent model” setting only controls the built-in Explore subagent; it’s separate from the model parameter the agent passes when you say “use a subagent with model X.”
For that parameter, the agent isn’t offered the full catalog but rather a curated subset: the agent-capable models that are enabled AND toggled visible in your main model picker. Models such as ones without Agent-mode support, BYOK models, etc., are filtered out.
To get GPT-5.5 or non-fast Composer 2/2.5 to appear as subagent options:
- Go to Cursor Settings → Models — make sure they’re enabled.
- Make sure they’re also visible in your model picker — visibility is what feeds the subagent list, not just being enabled.
- Start a new chat and ask which models it can use for a subagent.
If they’re already enabled + visible and still don’t show up, let me know, and we can look further at this.
