Hi,

I linked my account to the company copilot and enabled Codex 5.3, Opus 4.6 and Gemini 3. Only the latter shows up in Rider. Any clue why?

Hi,

It looks like only Gemini 3 is showing up in Rider because not all models you enabled are currently supported or fully available in the JetBrains Copilot plugin yet. GitHub Copilot has recently added support for new models like GPT-5.3-Codex, but they roll out gradually & sometimes require specific IDE/plugin versions or plan settings to appear. ([The GitHub Blog]1)

Additionally, model support in JetBrains IDEs (including Rider) can lag or be limited — certain Codex/Opus versions may not show up even if enabled in your Copilot account. Community reports suggest that IDE plugins sometimes don’t list all available models despite them being enabled on GitHub, and this can be a known limitation of the JetBrains integration at the moment. ([Reddit]2)

Here are a few things you can check:

1. Make sure Copilot plugin in Rider is updated — older versions may not expose the full model picker.
2. Some models (e.g., GPT-5.3-Codex or Opus variants) roll out gradually and may not be visible yet even if enabled in settings. ([The GitHub Blog]1)
3. If Rider doesn’t support a model yet, it simply won’t appear — this is expected with current JetBrains Copilot support.

Hope that helps!
