Introduction Several days ago, I setup ollama on my MacBook M4, and it works pretty well. At that time, I tried to use it with copilt with local models codegemma:7b and qwen3:8b. My expectation was not so high as the hardware configuration of my macbook pro m4 is just a entry level, just want to see how it works. I also learned there are other options such as vllm. After comparing the two, I found vllm is more flexible, powerful, product-ready, used widely in enterprises.
