- 发生了什么
- Pydantic AI Harness now includes AWSLambdaDurability, a capability that checkpoints every model request and tool call so Lambda handlers can resume after timeouts or retries without duplicating work.
- 为何重要
- Matters for engineers building AI agents on AWS Lambda that run longer than the invocation timeout or need to survive retries without re-executing expensive operations.
- 注意
- Changing agent shape, tool count, or model breaks in-flight executions. Tools run sequentially inside durable handlers, not in parallel. Requires specific IAM permissions and Lambda durable configuration.
