# TextResponseFormatJsonSchema
## Properties
**r#type** | **String** | The type of response format being defined. Always `json_schema`. |
**description** | Option<**String**> | A description of what the response format is for, used by the model to determine how to respond in the format. | [optional]
**name** | **String** | The name of the response format. Must be a-z, A-Z, 0-9, or contain underscores and dashes, with a maximum length of 64. |
**schema** | [**std::collections::HashMap<String, serde_json::Value>**](serde_json::Value.md) | The schema for the response format, described as a JSON Schema object. Learn how to build JSON schemas [here](https://json-schema.org/). |
**strict** | Option<**bool**> | Whether to enable strict schema adherence when generating the output. If set to true, the model will always follow the exact schema defined in the `schema` field. Only a subset of JSON Schema is supported when `strict` is `true`. To learn more, read the [Structured Outputs guide](/docs/guides/structured-outputs). | [optional]
