# Amazon Bedrock AgentCore Gateway adds InvokeModel support and fallback routing

> The gateway now lets you call any Bedrock model through one endpoint and automatically switches to a backup model if the first one fails.

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.

## The facts

- Feature announced on 2026-10-22
- Supported in all AWS Regions with AgentCore Gateway except China

## Why it matters
