This issue might be a duplicate of existing issues. Please check:

[FEATURE]: Expose GitHub Copilot "Auto" option in model selector #10093: Identical issue — same title, same description, same image (closed)
[FEATURE]: Request GitHub Copilot auto model routing API access + chat.model plugin hook #20235: Related open issue requesting GitHub Copilot auto model routing API access, which covers the same underlying feature request

With the recent change to the GitHub Copilot subscription, this might be an interesting feature to implement.

Implemented a plugin that enables this! See: https://github.com/m0wer/opencode-github-copilot-auto-model

@m0wer that doesn't use /models/session/intent

I’ve since updated it to follow Copilot auto-session flow via /models/session (with Copilot-Session-Token + runtime model override), which fixed the auto behavior/rate-limit mismatch in opencode.

It still does not directly call /models/session/intent itself; it relies on Copilot’s returned auto session selection. But works!

Looking better, so the gap is now on "chat.params" doing the call to /models/session/intent?

I just tried the plugin and I don't see auto in the /models picker...maybe I'm doing it wrong...

Should be called github-copilot/auto.

Now auto is exposed with a stable id: "auto", and chat.params/chat.headers reliably apply the runtime model override plus Copilot-Session-Token. There is a special session handling for the auto model.

But there is no gap left. opencode -m github-copilot/auto works and shows the auto assigned model in the TUI.

m0wer/opencode-github-copilot-auto-model#1 fixes the routing based on first message using /models/session/intent and scoping the selection to the session instead of globally. It follows the VSCode convention of sticking to the same model family and uses candidate_models instead of selected_model.

Huh. I mean I have:

    "github:m0wer/opencode-github-copilot-auto-model",

in my opencode.jsonc but when I try and run:

opencode -m github-copilot/auto

the TUI opens and I get in the upper right corner a popup saying:

🙁

This feature is also very important now that Copilot Student only accept auto model selection :/

The plugin is now working fine with the npm package instead of the GitHub install. And auto model works even after hitting 5h or weekly rate limits.

See https://github.com/m0wer/opencode-github-copilot-auto-model for the new install instructions.

So I put this in my opencode.jsonc file

"plugin": [
    [
      "opencode-github-copilot-auto-model",
      {
        "autos": [
          {
            "preferredModels": ["claude-sonnet-4.6", "claude-haiku-4.5"],
          },
          {
            "name": "Auto GPT/Codex",
            "preferredModels": ["gpt-5.4", "gpt-5.4-mini"],
          },
          {
            // Limited/best-effort: see "Gemini and other non-session models".
            "name": "Auto Gemini",
            "preferredModels": ["gemini-3.1-pro-preview", "gemini-3.5-flash"],
          },
        ],
      },
    ],
  ],

I'm able to see these options in the models list

Auto
Auto Claude
Auto GPT/Codex
Auto Gemini

No matter which one I chose, I'm still getting the error model is not supported. One thing I noticed is that if I start a new session with the Auto model, I saw briefly the notification stating a model like GPT 5.4 and reasoning something before this error appears.

That is weird. It is working just fine for me. I can do

Maybe try:

"opencode-github-copilot-auto-model@0.2.0"

to force the latest version? Maybe? I just tried and "Auto Claude", "Auto GPT", and "Auto Gemini" work for me just fine. And I see the toast popup with the model chosen.

@binbalenci

@binbalenci One thought. Maybe you need the "first" section for it to work? Not sure. But maybe:

"plugin": [
    [
      "opencode-github-copilot-auto-model",
      {
        "preferredModels": ["claude-sonnet-4.6", "gpt-5.3-codex"],
        "reasoning": ["claude-sonnet-4.6", "gpt-5.3-codex"],
        "noReasoning": ["gpt-5.3-codex", "claude-sonnet-4.6"],

        "autos": [
          {
            "preferredModels": ["claude-sonnet-4.6", "claude-haiku-4.5"],
          },
          {
            "name": "Auto GPT/Codex",
            "preferredModels": ["gpt-5.4", "gpt-5.4-mini"],
          },
          {
            "name": "Auto Gemini",
            "preferredModels": ["gemini-3.1-pro-preview", "gemini-3.5-flash"],
          },
        ],
      },
    ],
    "opencode-claude-auth@latest",
  ],

@mathomp4

@mathomp4 I did both of those and still not working. Which Copilot plan are you using?

It's for copilot pro+ annual subscription (only for the existing annual subscriptions).

ohhhhh. I'm on enterprise through work. Well, uh, it works for that too.

I think that this is still valid.
