我倾向考虑直接集成 AWS Bedrock 的统一接口方案（ Converse API ）。 https://docs.aws.amazon.com/bedrock/latest/userguide/conversation-inference.html

不然感觉一个一个 model 接入成本太高了，也不好维护，#3810 和 #4216 也同理

I tend to consider directly integrating AWS Bedrock's unified interface solution (Converse API). https://docs.aws.amazon.com/bedrock/latest/userguide/conversation-inference.html

Otherwise, it feels like the cost of accessing each model is too high and difficult to maintain. The same applies to #3810 and #4216.
