# Response formats

You can select from existing response formats or write a custom one.  Any of the following can be used by name passed to the `format` key in the `task.yml` or `info.yml` for folder-based tasks.


## Writing a Custom one

We recommend building off of [Pydantic `BaseModel`](https://pydantic.dev/docs/validation/latest/concepts/models/#basic-model-usage)



## Builtin
```{eval-rst}
.. automodule:: benchtools.response
    :members:
```
