Request failed with status code 404

Since upgrading to v0.48, I’m getting this error using chatgpt-4o-latest using both Ask and Agent mode:

Request failed with status code 404: {
  "error": {
    "message": "tools is not supported in this model. For a list of supported models, refer to https://platform.openai.com/docs/guides/function-calling#models-supporting-function-calling.",
    "type": "invalid_request_error",

  }
}
