Amazon Bedrock AgentCore Gateway now works with the InvokeModel and InvokeModelWithResponseStream APIs. This means you can point your existing Bedrock SDK at the gateway and reach any model provider without changing your code. The gateway also adds model fallback: if the primary model is throttled, out of capacity, or unreachable, it automatically sends the request to a backup model you specify. Fallback routing and a built‑in circuit breaker happen behind the scenes, so clients see only one request and one response.
Why it matters
Developers can keep their AI agents running smoothly without writing custom retry logic.
