Route Around a Dead Primary Model

Fix an LLM proxy with no working fallback path.

A intermediate AI Engineering challenge worth 10 points. Solve it hands-on in a real AI Engineering environment in your browser - no local setup, no fake shells.

The Challenge

Scenario: A LiteLLM proxy's primary route points at a large model that was never installed on this host, and there is no fallback - every request just fails.

Configure the primary route to the preloaded qwen2.5:0.5b and a real fallback to smollm2:135m, then prove a real proxy request succeeds even when the primary is forced unavailable. Run check.
