Copilot CLI does not list all org-enabled models (e.g. Gemini 3.1 Pro) while VS Code Copilot does

[Smotrov]

Describe the bug

Summary

Copilot CLI shows a reduced model list compared to VS Code Copilot on the same GitHub account and organization, even though the missing models are enabled in organization Copilot settings and are available in VS Code Copilot.

A concrete example is Gemini 3.1 Pro:

• Enabled in org Copilot settings
• Available and selectable in VS Code Copilot
• Not listed in Copilot CLI model selector

There is no documentation explaining this difference, and the official Supported models page does not mention any client-specific limitations.

---

Documentation gap

The following page lists supported Copilot models but does not describe any per-client differences:

https://docs.github.com/en/copilot/reference/ai-models/supported-models

There is also no mention of model availability differences in Copilot CLI documentation or troubleshooting pages.

---

Question

Is the reduced model list in Copilot CLI:

• an intentional limitation,
• a rollout delay,
• or a bug in model discovery / listing?

If intentional, could this be documented explicitly?

Affected version

v0.0.418

Steps to reproduce the behavior

Observed behavior

In Copilot CLI, the model selector shows:

Claude Sonnet 4.6
Claude Haiku 4.5
Claude Opus 4.6
Gemini 3 Pro (Preview)
GPT-5.3-Codex
GPT-5.1-Codex
GPT-5.1-Codex-Mini (Preview)
GPT-5 mini
GPT-4.1

However, Gemini 3.1 Pro is missing.

At the same time:

• Gemini 3.1 Pro is enabled in GitHub organization Copilot settings
• Gemini 3.1 Pro is visible and usable in VS Code Copilot

Expected behavior

Either:

1. Copilot CLI should list all models enabled for the organization, consistent with VS Code Copilot
   or
2. Official documentation should clearly state that:
   • Copilot CLI supports only a subset of Copilot models
   • Certain models (e.g. Gemini 3.1 Pro) are intentionally unavailable in CLI

Currently, neither behavior nor limitation is documented.

Additional context

  • GH_TOKEN – not set
  • GITHUB_TOKEN – not set

Same issue here. Running v0.0.419 on macOS (Apple Silicon), Copilot Pro+ subscription. Gemini 3.1 Pro is available and works fine in VS Code Copilot, but does not appear in the CLI model selector. 👍 for visibility.

Same, we enabled Claude Sonnet 4.6, it shows up, and we enabled Gemini 3.1, nothing.

Gemini CLI also doesn't support Gemini 3.1 Pro, so it seems 3.1 isn't available in the CLI yet. It's only available in some environments.

Interestingly enough, Droid claims to support Gemini 3.1 Pro, but I don't have a subscription to check.
