Some models not available in Copilot CLI with Pro

Copilot in GitHub

Body

Copilot CLI version: 1.0.11

I have a GitHub Copilot Pro subscription. Some time ago, the possibility to enable/disable models via the Account > Copilot Settings page, have disappeared. Instead, documentation states that, if not member of an organization (and this is a private account and subscription), one does not have to hand-pick models. And yet, in my GitHub Copilot CLI, I only have the following models available:
Claude Sonnet 4.6
Claude Sonnet 4.5
Claude Haiku 4.5
Claude Opus 4.6
Claude Opus 4.5
Claude Sonnet 4
Gemini 3 Pro (Preview)
GPT-5.4
GPT-5.3-Codex
GPT-5.2-Codex
GPT-5.2
GPT-5.1-Codex-Max
GPT-5.1-Codex
GPT-5.1
GPT-5.4 mini
GPT-5.1-Codex-Mini (Preview)
GPT-5 mini
GPT-4.1
If I check for example in JetBrains PyCharm, I can see Grok, Gemini 3 Flash (preview) and GPT-4o, for example. But these don't show up in Copilot CLI. If I try explicitly switching to, say, /model GPT-4o, I get a "Model GPT-4o is unsupported." error message.
What am I doing wrong? What should I check/change?

You are not doing anything wrong — this is expected behavior.

The key point is that model availability in Copilot CLI is not the same as in IDE integrations (like PyCharm or VS Code).

Why you don’t see models like GPT-4o or Gemini Flash

Copilot CLI only exposes a subset of models that are officially supported in the CLI environment. Even with a Copilot Pro subscription:

• Not all models are available across all surfaces (CLI, IDE, Chat, etc.)

• Some models (e.g., GPT-4o, Gemini Flash, Grok) may be:

  • Limited to specific integrations (like JetBrains or VS Code)
  • In preview or staged rollout
  • Restricted due to performance or UX constraints in CLI

That’s why /model GPT-4o returns:

"Model GPT-4o is unsupported."

---

Why settings to enable/disable models disappeared

For individual (non-organization) users:

• GitHub now manages model availability automatically

• Manual model selection controls have been removed in many cases

• Available models depend on:

  • Client (CLI vs IDE)
  • Feature rollout stage
  • Backend configuration

---

What you can check

• Ensure you are using the latest Copilot CLI version
• Run any CLI update/refresh commands if available
• Verify your Copilot Pro subscription is active

---

Important takeaway

Copilot Pro gives you access entitlement, but not uniform model access across all tools.

Different environments (CLI, JetBrains, VS Code) may expose different model sets at the same time.

---

Suggestion

If consistent model access across tools is important, it would be worth requesting:

• Unified model availability across Copilot surfaces
• Clear documentation of which models are supported where

This seems more like a product limitation / rollout difference than a misconfiguration.
