我按照你的改了，还是有问题

我认为仅通过优化提示并提供示例只能提示LLM，但无法强制其输出正确的JSON格式，效果仍然不理想。我不确定是否有其他开源LLM支持像OpenAI那样的JSON输出模型，但你可以尝试一些更大的LLM，可能会更好地遵循提示和示例中的指示。

You’re right. While an optimized prompt with examples can guide the LLM, it can’t guarantee the correct JSON output. There’s still some inconsistency. I’m not sure if other OSS LLMs support JSON output as well as OpenAI’s models do, but trying a larger LLM might improve adherence to the instructions and examples in the prompt.
