Body

Hello,

I am trying to use the Claude model in GitHub Copilot inside VS Code, but I cannot use it even though the model appears in the Language Models list.

When I select the model, I get this message:

"This model is not available. Contact your administrator to enable it."

Details:

• VS Code version: 1.111.0
• Copilot extension: latest version
• Copilot Chat extension: latest version
• Copilot plan: Copilot Pro

What I have already tried:

• Enabled all Copilot features in https://github.com/settings/copilot/features
• Restarted VS Code
• Reloaded window
• Signed out and signed in to Copilot
• Verified that Claude Haiku 4.5 appears in the Language Models list

However, the model still cannot be used in Copilot Chat.

Screenshot:

Is there an additional setting required to enable Claude models for Copilot Chat?

Thank you.

**Important Note

Even with Copilot Pro, some Claude models such as:

Claude 3 Opus

Claude Haiku 4.5

may still be part of a limited rollout or restricted to organization/enterprise environments. In such cases, the model may appear in the list but cannot be used yet.**

I can enable GPT 5.4. But Claude Opus disabled.

Claude Opus Disabled

Claude Opus (from Anthropic) is a different AI model.

If it shows disabled, it usually means:

Your plan doesn’t include it, or

The platform removed or temporarily disabled access, or

They replaced it with another model.
--->Good news: GPT-5.4 is generally stronger than most Claude models for coding and technical tasks.

Your reply is the entirely same as ChatGPT outputs, it seems helpless

Facing the same issue even having the Pro subscription and with the remaining premium request.

if you were using that on student pack then github have revoked the students from using claude models

same problem

It is like it may be an admin or feature rollout limitation even if the model appears in the list. Sometimes access takes time to fully activate. I saw a similar tip mentioned while checking spin harta download, might be worth a quick look too.

Step-by-Step Solution Guide
Step 1: Verify Your VS Code Version and Extensions
Ensure you are running VS Code 1.109 or newer . You can check this in Help > About.

Make sure both the GitHub Copilot and GitHub Copilot Chat extensions are updated to their latest versions.

Step 2: Check GitHub Feature Settings (Revisit)
Go to https://github.com/settings/copilot/features.

Even though you've done this, double-check that the Claude models (e.g., "Claude 3.7 Sonnet") are toggled ON. Because you are on a Copilot Pro plan, you should have access to models like Claude 3.5 Sonnet, Claude 3.7 Sonnet, and Claude Opus 4.5 .

Step 3: Select the Model Correctly in VS Code (Crucial Step)
This is the most likely fix. The model picker UI can be misleading .

In VS Code, open the Copilot Chat view.

Click on the model picker (where it currently shows, for example, "GPT-4o").

Look for an option that says "Manage Models..." or similar.

In the list that appears, your instinct might be to click on a company name like "Anthropic" to enable Claude. Do not do this. Instead, find and select the option named "Copilot" .

Clicking on "Copilot" should reveal a sub-menu or list of the specific AI models available through your Copilot subscription, including the Claude models.

Select the desired Claude model (e.g., "Claude 3.7 Sonnet") and confirm your selection.

The model picker should now show your chosen Claude model, and chat requests should work.

Step 4: Consider Regional Access
If the above steps fail, and you are in a region where access to certain AI services might be limited, testing with a VPN connected to a different country (like the US) can help determine if this is the cause .

Step 5: Contact GitHub Support
If none of these steps work, the issue may be on GitHub's side.

Open a support ticket with GitHub, clearly explaining the steps you have taken and providing your VS Code version and Copilot plan details. You can create a ticket here: https://support.github.com/contact/account. Referencing similar community discussions can also be helpful .

Why This Happens (Even with Copilot Pro)
Limited Rollout / Phased Availability – Some Claude models (like Claude 3 Opus, Claude Haiku 4.5) may be in a staged rollout. They can appear in the UI but aren't fully activated for all Pro users yet.

Account Type Restrictions – If you're using a GitHub Student Developer Pack subscription, recent changes may have revoked access to Claude models (several users in the thread reported this).

UI Selection Confusion – The model picker in VS Code can be misleading. Simply clicking "Anthropic" in the list often does not enable the model – you need to select the specific model through the "Copilot" entry.

✅ Step‑by‑Step Troubleshooting

1. Verify Your Plan & Model Availability
   Go to GitHub Copilot settings and scroll down to the model toggles.
   Make sure the specific Claude model you want (e.g., "Claude 3.7 Sonnet") is switched ON.
   Note: Some models may not appear here at all if they're not yet enabled for your account.

2. Update Everything
   VS Code ≥ 1.109 (you're on 1.111 – good).

GitHub Copilot and GitHub Copilot Chat extensions: update to the latest versions via the Extensions panel.

3. The "Manage Models" Trick (Crucial)
   Open the Copilot Chat view in VS Code.

Click on the current model name in the chat input area (e.g., "GPT‑4o").

Select "Manage Models..." from the dropdown.

In the list that appears, do NOT click on "Anthropic" directly. Instead, find and click on "Copilot" (this expands the list of models actually available through your subscription).

From the expanded list, choose the desired Claude model (e.g., "Claude 3.7 Sonnet").

The chat model indicator should now show your chosen model, and requests should work.

Many users in the thread reported that this "Copilot" sub‑menu was the missing piece – the models were there but hidden behind that extra step.

4. Sign Out / Sign In
   Run GitHub Copilot: Sign Out from the Command Palette (Ctrl+Shift+P).

Then run GitHub Copilot: Sign In and re‑authenticate.

5. Check Regional Availability
   If you're in a region with restricted AI service access, try temporarily connecting through a VPN to a location like the US and repeat step 3.

6. Contact GitHub Support
   If none of the above works, open a ticket at GitHub Support. Include:

Your VS Code version, extension versions.

Confirmation that you're on a paid Copilot Pro plan (not student pack, if applicable).

📌 Important Note
If you are using the GitHub Student Developer Pack, some users in the thread mention that access to Claude models has been revoked for student accounts. In that case, you would need a regular paid Pro subscription to use them.

I hope one of these steps resolves the issue. If you're still stuck, feel free to share more details (like whether you're on a student pack) and I can help further!
