GitHub Models OpenAI Compatible API not working with documented URL change

[gwtaylor]

Bug description

I had success using a GitHub Models configuration like this:

[OPENAI]
compatible=true
key=github_pat_...
url=https://models.inference.ai.azure.com
path=/chat/completions
model=gpt-4.1-mini

However, the GitHub Models docs show that they have changed their REST API to use a different URL.
The model docs in the Marketplace show that the URL should now be pointed towards https://models.github.ai/inference.
So I believe the configuration should look like this:

[GITHUB]
compatible=true
key=github_pat_...
url=https://models.github.ai/inference
path=/chat/completions
model=openai/gpt-4.1-mini

I get a 404 Error when I use this new URL.
Has anyone had success using the new URL? I have tried various permutations on this and can't seem to find anything that works with the documented URL.
To be clear, the old one still works but I would prefer to use the documented one in case the old one is deprecated.

The new URL works for me using the Python SDK. However, it doesn't work in aicommit2.

aicommit2 version

v2.2.18

@gwtaylor I'm sorry for the late response.
I've looked into this issue. The current implementation of aicommit2 already uses the new GitHub Models API URL correctly.

In the code:

• baseURL is set to 'https://models.github.ai'
• The endpoint path /inference/chat/completions is appended to it
• Final URL becomes: https://models.github.ai/inference/chat/completions

The issue you're experiencing is because GitHub Models service in aicommit2 doesn't support the path configuration option that OpenAI service does. While OpenAI allows you to customize the API path, GitHub Models uses a fixed endpoint structure.
So you don't need to configure any URL manually for GitHub Models
