Replace Azure Inference URL with GitHub Models API URL

[pamelafox]

Issue Description

This repository contains references to the old Azure inference URL that should be updated to use the new GitHub Models API endpoint.

Current URL

https://models.inference.ai.azure.com

New URL

https://models.github.ai/inference

Why change is needed

For GitHub Models API, the Azure inference endpoint is being deprecated:
https://github.blog/changelog/2025-07-17-deprecation-of-azure-endpoint-for-github-models/

Action required

• For all files that support GitHub Models, replace all instances of https://models.inference.ai.azure.com with https://models.github.ai/inference in the affected files.
• If there is a model name that is being used with GitHub Models in the code, like "gpt-4o", change that model name to "openai/gpt-4o" instead - put "openai/" in front.

For example, this new code would be correct when using GitHub Models with OpenAI:

if API_HOST == "github":
client = openai.OpenAI(
base_url="https://models.github.ai/inference",
api_key=os.environ["GITHUB_TOKEN"],
)
MODEL_NAME = os.getenv("GITHUB_MODEL", "openai/gpt-4o")
