## Human Summary
OpenAI Python SDK v3.25.0 introduces enhancements for agents and tools, including observing local tool failures, executing local tools during streamed session creation, and supporting tool search with deferred loading in typed function helpers.

## Agent Summary
OpenAI Python SDK v3.25.0 updates agent and tool workflows: adds local tool failure observation, enables running local tools during streamed session creation, exposes agent turn items and usage source grouping, and adds tool search (defer loading=true) support in typed function helpers.

## Body
The OpenAI Python SDK v3.25.0 release includes multiple new features centered on agents and tools. Specifically, the SDK now supports observing local tool failures (PR 4028) and executing local tools during streamed session creation (PR 4027). The API layer adds support for agent turn items and usage source grouping (PR 4030). Additionally, typed function helpers now support tool search with defer loading=true (PR 4029), and the library publicly exports the type for the response format parameter (PR 2993).

## Recommended actions
- Upgrade openai python package to version 3.25.0 to use the new agent turn items and streaming tool execution features.
- Inspect local tool error-handling implementations to integrate the new local tool failure observation capabilities.
- Evaluate typed function helpers to leverage tool search with deferred loading where applicable.
