Amazon Bedrock Server-Side Tools in Responses API

Amazon Bedrock now supports server-side tools in the Responses API using OpenAI API-compatible service endpoints. This enables your AI applications to perform real-time, multi-step actions such as searching the web, executing code, and updating databases within the organizational, governance, compliance, and security boundaries of your AWS accounts.

What to do

• Submit your own custom Lambda function to run custom tools.
• Use AWS-provided tools, such as notes and tasks.

Server-side tools using the Responses API is available starting today with OpenAI's GPT OSS 20B/120B models in multiple AWS Regions.
