📄 Description

Overview

Adds documentation for enabling real-time streaming of tool calls and structured output when using Anthropic models through AWS Bedrock.

By default, Bedrock buffers tool call arguments until the JSON is complete. This documents how to enable Anthropic's fine-grained tool streaming beta via additional_model_request_fields to get incremental streaming.

Type of change

Type: Update existing documentation
