Tools
Functions exposed to the LLM to take actions
| Name | Description |
|---|---|
| openai_web_searchA | OpenAI Web Search with reasoning models. For quick multi-round searches: Use 'gpt-5-mini' with reasoning_effort='low' for fast iterations. For deep research: Use 'gpt-5' with reasoning_effort='medium' or 'high'. The result is already multi-round reasoned, so agents don't need continuous iterations. Supports: gpt-4o (no reasoning), gpt-5/gpt-5-mini/gpt-5-nano, o3/o4-mini (with reasoning). |

There is only one tool, so there is no possibility of confusion or overlapping purposes. The tool's purpose is clear and singular.
With a single tool, the naming is inherently consistent. 'openai_web_search' follows a clear verb_noun pattern and clearly indicates its function.
The server is dedicated to OpenAI web search, and a single tool fully covers this narrow purpose. While under the typical 3-15 range, it is not excessive or trivial, making the count reasonable for the scope.
For a web search server, the tool provides comprehensive functionality, handling multiple models, reasoning efforts, and multi-round searches. There are no obvious missing capabilities for the stated purpose.
