```plaintext
Trying to contact the model returned this error: { "error": { "message": "Unsupported value: 'messages[0].role' does not support 'system' with this model.", "type": "invalid_request_error", "param": "messages[0].role", "code": "unsupported_value" } }

```

It seems these new models do not support a system role. o1-mini is 80% cheaper then the top model, might be useful for complex tasks.
