This issue requires improving the code for the StepFun, Baichuan, and Yi models using the local.go code style.
Currently, these three models use OpenAI-style interfaces to initiate requests, but they do not reuse the local.go code (local.go can be regarded as a utility class that can be used to reuse OpenAI request initiation and result processing).
You can refer to the TencentCloud and AlibabaCloud code.
