It isn't odd at all. Ollama uses an ancient version of llama.cpp, and was originally meant to just be a GUI frontend. They forked, and then never resynchronized... and now lack the willpower and technical skill to achieve that. Ollama is essentially a dead, yet semi-popular, project with a really good PR team. If you really want to do it right, you use llama.cpp.
