[felinae99]

问题描述 希望能够添加grok的绘图api接口。目前绘图只有openai的dall-e 如grok-2-image-1212

{ "code": "Client specified an invalid argument", "error": "The model grok-2-image-1212 is an image model and is therefore not available on this endpoint. Please use a compatible endpoint such as https://api.x.ai/v1/images/generations. For more information, see https://docs.x.ai/docs/api-reference#image-generations" }
