# Cerebras OpenAI Tool Use

> Call WebSearchTools from a CerebrasOpenAI agent in sync and async modes.

<Warning>
  This example uses a Cerebras model ID that has been retired. Replace the retired ID with `gpt-oss-120b` before running. Review the [Cerebras migration notes](https://inference-docs.cerebras.ai/support/deprecation) when the example uses reasoning, tools, or structured output.
</Warning>
