ONNX模型转换：AI模型跨平台部署
模型在PyTorch里训练好了，但想部署到手机、网页、或者用别的框架跑。ONNX就是模型界的「通用格式」。

模型在PyTorch里训练好了，但想部署到手机、网页、或者用别的框架跑。ONNX就是模型界的「通用格式」。
ONNX是什么
ONNX（Open Neural Network Exchange）是微软和Facebook联合推出的模型交换格式。
类比：JPEG是图片的通用格式，ONNX是模型的通用格式。
import torch
# PyTorch模型转ONNX
dummy_input = torch.randn(1, 3, 224, 224)
torch.onnx.export(model, dummy_input, "model.onnx")
转成ONNX后，可以在任何支持ONNX的框架上跑。
主要适用小模型（视觉、语音）而非大语言模型。大模型现在更常用GGUF格式。
Why This Matters
Understanding this topic is essential for anyone building AI applications in 2026. As AI agents become more integrated into production workflows, knowing how to properly implement these patterns can be the difference between a prototype and a reliable system.
Practical Tips
- Start simple and iterate. Dont try to implement everything at once.
- Test with real user scenarios before going to production.
- Monitor performance and collect feedback for continuous improvement.
- Keep learning - this field evolves rapidly.
Common Mistakes to Avoid
- Over-engineering: solving problems you dont have yet
- Under-testing: not validating edge cases
- Ignoring costs: not monitoring token consumption
- Skipping documentation: not documenting your prompts and configurations
Remember: the best AI agent is the one that actually works for your specific use case.
