刚看到 gemini-2.5系列快下架了，所以在 newapi 里试了下把模型改成 gemini-3-flash原来的只需要在 在参数覆盖里配置 
{   "tools": [     {       "google_search": {}     }   ] } 
但是我试了下 gemini-3-flash 加了这个参数后会报错：Error code: 404 - {‘error’: {‘message’: ‘models/gemini-3-flash is not found for API version v1beta, or is not supported for generateContent. Call ListModels to see the list of available models and their supported methods.’ 
但是如果不填这个参...
