01What must the replacement support?
Inventory provider preferences, fallback chains, model aliases and plugins. Check which behaviors belong to OpenRouter rather than the model itself. Keep the current route for dependencies that LLMFly has not explicitly documented or passed in your tests.
02What changes in my current client?
Copy the target platform's model ID instead of assuming provider/model aliases transfer unchanged. Audit OpenRouter-specific routing fields and headers, then test the standard request fields on the selected LLMFly AI route.
03What should you test before switching?
Replay the same prompts on one explicit model version. Measure response quality, latency, tool results and billed tokens, including failed attempts. Test an unavailable model to confirm what your application does instead of relying on silent fallback.
