react模板放在system和user的区别？

我发现qwen的原生agent的react是放在了user上，而swift官方提供的ms_agent的react放在了system中，这两者有何区别，或者哪种更好？

Qwen：

<|im_start|>system
You are a helpful assistant.<|im_end|>
<|im_start|>user
Answer the following questions as best you can. You have access to the following APIs

ms_agent

<|im_start|>system

或者说，我如果用ms_agent的格式去训练，那么就不能额外的添加系统指令了吧，会影响推理效果，比如将ms_agent的system改成如下：

<|im_start|>system
You are a helpful assistant.

一般放在system中更好的 参考：https://swift.readthedocs.io/zh-cn/latest/LLM/Agent%E5%BE%AE%E8%B0%83%E6%9C%80%E4%BD%B3%E5%AE%9E%E8%B7%B5.html
