Endpoint Features and Use Cases
bedrock-mantle

Use for: Easily migrating from other models that use the OpenAI-compatible APIs.

Features: Supports both client and server side tool use with Lambda functions and comes configured with ready-to-use tools in your applications.

Recommended for: New users to Amazon Bedrock.
bedrock-runtime

Supports Amazon Bedrock native APIs (Invoke API, Converse API). Also supports the OpenAI-compatible Chat Completions API.

Use for: Running any model supported by Amazon Bedrock. The Converse API provides a unified interface for interacting with all models in Amazon Bedrock and the Invoke API provides direct access to models with more ability to control the request and response format. You can also use Chat Completions API to interact with your models.

Features: Supports only client-side tool use with Lambda functions and does not come pre-configured with ready-to-use tools. Allows you to track usage and costs when invoking a model.

If you are new to Amazon Bedrock, we recommend you start with the bedrock-mantle endpoint.
