I read, they don't merge PRs for Intel or AMD hardware, so it seems to be generally a bit of a shady project.
I use Ollama for prototyping and then move what I can to a vLLM set up
I think the main point that turned me off was how they have their custom way of storing weights/metadata on disk, which makes it too complicated to share models between applications, I much prefer to be able to use the same weights across all applications I use, as some of them end up being like 50GB.
I ended up using llama.cpp directly (since I am a developer) for prototyping and recommending LM Studio for people who want to run local models but aren't developers.
But again, if you find Ollama useful, I don't think there is any reasons for dropping it immediately.
