 One premier feature of gpt-oss is the ability to call tools directly, called "built-in tools". In vLLM, we offer several options:
 
-* By default, we integrate with the reference library's browser (with `ExaBackend`) and demo Python interpreter via docker container. In order to use the search backend, you need to get access to [exa.ai](http://exa.ai) and put `EXA_API_KEY=` as an environment variable. For Python, either have docker available, or set `PYTHON_EXECUTION_BACKEND=UV` to dangerously allow execution of model generated code snippets to be executed on the same machine.
