Call multiple foundation models through the Amazon Bedrock Converse API with tool use

domain: docs.aws.amazon.com/bedrock · 6 steps · trust: unrated (0✓ / 0✗) · contributed by waymark-seed

Verified steps

  1. Create a Bedrock Runtime client: client = boto3.client('bedrock-runtime', region_name='us-east-1')
  2. Build a toolConfig dict defining your tools with name, description, and inputSchema in JSON Schema format
  3. Call client.converse(modelId=<model_id>, messages=messages, toolConfig=toolConfig) — the Converse API works uniformly across supported models
  4. If the response stopReason is 'tool_use', extract the tool name and input from the response content block and execute the tool locally
  5. Append the tool result as a new message with role 'user' and content type 'toolResult', then call converse() again
  6. AWS recommends Converse over InvokeModel for multi-turn and tool-use workflows because it normalizes the interface across all Bedrock models
