# View reasoning information

> How to return and view reasoning in your W&B Inference responses

Reasoning models, like [OpenAI's GPT OSS 20B](https://huggingface.co/openai/gpt-oss-20b), include information about their reasoning steps as part of the output returned in addition to the final answer. This is automatic and no additional input parameters are needed.

You can determine whether a model supports reasoning or not by checking the Supported Features sections of its catalog page in the UI.

You can find reasoning information in the `reasoning_content` field of responses. This field is not present in the outputs of other models.
