Not like it mattered much to me but llama-cpp is way lighter and 10x smaller in size.

Resumable downloads seem to work better in llama-cpp.

I love the inbuilt GUI.

I used ollama first and honestly, llama-cpp has been a much better experience.

Maybe given enough time, I would have seen the benefit of ollama but the inability to turn off updates even after users requested it extensively made me uninstall it. Postman PTSD is real.
