Configure model fallback chains for reliability. Use when building resilient systems that need high availability. Trigger with phrases like 'openrouter fallback', 'model fallback', 'openrouter backup model', 'failover config'.

This skill shows how to configure fallback model chains so requests automatically retry with alternative models when the primary model is unavailable or errors.
models field (instead of model) — OpenRouter will try each in order until one succeedsroute field with "fallback" strategy to let OpenRouter handle failover automaticallyrequest_timeout per attempt so slow models fail fast and the fallback triggers quickly| Error | Cause | Fix |
|---|---|---|
| All fallbacks exhausted | Every model in the chain failed | Add more diverse fallbacks across providers; alert on full chain failure |
| Slow cascading retries | Each model timing out sequentially | Reduce per-model timeout to 10-15 seconds; use parallel fallback instead |
| Inconsistent responses | Different models in the chain have different capabilities | Ensure all fallback models support the features your prompt uses (e.g., tool calling) |
