Body

Using the latest Copilot CLI standalone, user have reported the below error message :

✗ No model available. Check policy enablement under GitHub Settings > Copilot

✗ No model available. Check policy enablement under GitHub Settings > Copilot

Total usage est: 0 Premium requests
Total duration (API): 0.0s
Total duration (wall): 16.6s
Total code changes: 0 lines added, 0 lines removed

However, while checking the logs, we were able to see the below, which points that the Copilot CLI attempted to make use of the individual Copilot API instead of the Enterprise Copilot API for the EMU, which resulted in a mismatch error message and subsequently "No model available" error message:

Make sure the enterprise (or organization) has the correct licence for Copilot (e.g., Copilot Business / Copilot for Enterprise) rather than just an individual user licence.

In the GitHub Enterprise/Org settings:

• Navigate to https://github.com/enterprises/<your-enterprise>/settings/copilot (replace accordingly).
• Enable “GitHub Copilot CLI” (or any setting referring to CLI access).
• Ensure model access policies are enabled (i.e., no blanket block of models).
• Under the same settings, verify licensing: who has seats, are they assigned, etc.

This confirms the root cause of the 'No model available' error is that the Copilot CLI standalone is incorrectly attempting to use the individual Copilot API endpoint ( https://api.individual.githubcopilot.com/mcp/readonly ) instead of the correct Enterprise Managed User (EMU) API endpoint.

Since this looks like a bug in the CLI's endpoint routing, the immediate solution is to ensure the CLI is forced to use the correct Enterprise configuration.Verify Authentication: Ensure the user is signed in correctly to their GitHub Enterprise instance and that the CLI is using the Enterprise token (usually handled via $\text{gh auth login}$).Check/Set Environment Variable (Likely Fix): You may need to explicitly configure the GitHub Host using an environment variable before running the CLI, although this should ideally be automatic.

Try setting: in Bash

export GITHUB_HOST="your-enterprise-domain.com"
# Then run the Copilot CLI command
copilot ...

I'm getting the no model available issue too. Our organization enabled copilot cli. Other users in my organization are able to see models. Not all of them. I personally cannot. I continue to get the message:

✗ No model available. Check policy enablement under GitHub Settings > Copilot

When I review the logs, I see this:

Is this issue because my organization authorizes my personal account inside of their organization? Is it failing to authorize my account to my organization via copilot cli?

[tombohub]

So cli is available only for enterprise users??

I'm experiencing a similar issue, but specifically only with Claude Sonnet 4.5. Other models (GPT-4, Claude 3.5 Sonnet) work fine in my GitHub Copilot setup.

Error Details:

Request Failed: 400 {"error":{"message":"no endpoints available for this model under your current plan and policies","code":"no_available_model_endpoints"}}

My Setup:

GitHub Copilot Individual plan
VS Code with Copilot extension
All other models work normally
Only Claude Sonnet 4.5 triggers this specific error
Request ID for reference: 862fe2f1-4fc6-480c-ac16-83505a12ddea
GH Request ID: D487:213395:7E4939:A0D3B0:69294224

This seems to be a model-specific availability issue rather than a general authentication/policy problem, since other Claude models work fine. Could this be related to:

Gradual rollout - Claude Sonnet 4.5 may not be fully available to all plan tiers yet
Regional availability - The model might be limited to certain regions
Plan-specific restrictions - Even if the model exists, it might require a higher tier plan
It would be helpful to get clarification on:

Which GitHub Copilot plans currently support Claude Sonnet 4.5
Any regional restrictions for this model
Expected timeline for broader availability
Thanks for tracking this issue!

I am also seeing Sonnet 4.5 issues with this weird error message. This model has been my primary model since the day it came out and no changes has been done to my business plan. This must be some kind of issue with the model but the error message is just completely wrong.

[Darkskynet]

I got this error this morning with the Sonnet 4.5, but Opus 4.5 seems to be running fine, so this is possibly an issue with the specific model based on the comments here so far?

[kapilkumar9976]

i'm getting the same error for Sonnet 4.5, What's the issue?

[ephraimd]

I'm getting the same error also with Claude Sonnet 4.5. I still used it less than 10 hours ago and I've made no changes to my configurations. Something is definitely wrong with either the model or copilot.

[naeemdhby]

I'm also starting to get the error below on claude-sonnet-4.5 model:
Model call failed: {"message":"no endpoints available for this model under your current plan and policies","code":"no_available_model_endpoints"}
