When does this happen?

IF On importing litellm, an HTTP GET request is made to fetch model_prices_and_context_window.json, even if cost tracking is not used.

How others solved it

THEN Lazy-load the pricing data by deferring the HTTP request until cost is actually needed. As a workaround, ensure network access to raw.githubusercontent.com or mock the request during tests. If you never use cost features, consider patching the import to suppress the fetch.

python -c "import logging; logging.basicConfig(level=logging.INFO); import litellm" # This will log the unwanted HTTP request
