  suggestion (non-blocking): we could extend this util to return all the required fields for the default model

  export const formatDefaultModel = (defaultModel) => {
    const name = defaultModel?.name
      ? sprintf(__('%{modelName} - Default'), { modelName: defaultModel.name })
      : '';
  
    return {
      text: name,
      value: GITLAB_DEFAULT_MODEL,
      provider: defaultModel?.modelProvider,
      description: defaultModel?.description,
    };
  };
