@liugddx It seems this model may have compatibility with the OpenAI API, so it might not need to be added separately—similar to the considerations discussed in #1712. Just a thought!

Thank you for your reply. At present, xinghuo is not fully compatible with openai. Of course, I will reuse the capabilities that are already compatible with openai. If there is no compatibility, I suggest that we need to implement it separately.
