feat: add fallbackModel option for automatic model failover on provider errors#1136
Conversation
…er errors When a primary model returns a retryable HTTP status (429, 500, 502, 503), the SDK now automatically re-issues the request to a user-specified fallback model. This unblocks users hitting transient "high demand" errors on models like Gemini 2.5 Flash Lite by transparently offloading to a backup model (e.g., Gemini 2.5 Pro). The fallback model gets a single attempt to prevent infinite loops and can be from a completely different provider. Adds fallbackModel/fallback_model to GuardOptions, RedactOptions, and ScanOptions in both TypeScript and Python SDKs with full test coverage.
