feature patch

Anthropic has released version 0.122.0 of its Python SDK, introducing an `output_behavior` parameter for dream creation that allows specifying a new memory store or updating an existing one. This release also includes multiple bug fixes, enhancing the SDK's stability and consistency across various integrations. Key improvements address asynchronous client signing in Bedrock, expose beta APIs for messages and tool running, and refine streaming message accumulation. Developers using the Python SDK for AI model interactions, particularly with AWS Bedrock or Google Cloud Vertex AI, are affected by these updates.

  • →add output_behavior to dream creation (create a new memory store or update the input store in place)
  • →bedrock,aws: run SigV4 signing off the event loop in async clients
  • →expose beta.messages.parse, stream and tool_runner
  • →add models
  • →keep token exchange bound per client across copy()
