## TL;DR

Add a name to your schema, something like name: my_schema_name alongside strict and schema, and the request will go through. The same code worked before the upgrade, so something changed in how the SDK sends the format.

## Steps

1. After upgrading to cerebras-cloud-sdk 1.16.0, using response_format with the json_schema type fails with: Unsupported response_format type: json_schema, code wrong_api_format. My schema itself looks valid. The same code worked before the upgrade, so something changed in how the SDK sends the format.

2. The error is because the name field is required for json_schema response formats. Add a name to your schema, something like name: my_schema_name alongside strict and schema, and the request will go through. Worth noting that json_schema support was pretty new around that SDK version, so the docs did not call out the required fields clearly.
