Force JSON object response format

Users can now force command-nightlyto generate outputs in JSON objects by setting the response_format parameter in the Chat API. Users can also specify a JSON schema for the output.

This feature is available across all of Cohere’s SDKs (Python, Typescript, Java, Go).

Example request for forcing JSON response format:

cURL

POST https://api.cohere.ai/v1/chat
{
    "message": "Generate a JSON that represents a person, with name and age",
    "model": "command-nightly",
    "response_format": {
        "type": "json_object"
    }
}

Example request for forcing JSON response format in user defined schema:

cURL

POST https://api.cohere.ai/v1/chat
{
    "message": "Generate a JSON that represents a person, with name and age",
    "model": "command-nightly",
    "response_format": {
        "type": "json_object",
        "schema": {
            "type": "object",
            "required": ["name", "age"],
            "properties": {
                "name": { "type": "string" },
                "age": { "type": "integer" }
            }
        }
    }
}

Currently only compatible with `command-nightly model.
