It is open-weight, we dont have access to the training code nor the dataset.

That being said it should be safe for your computer to run Deepseeks models since the weight are .safetensors which should block any code execution from injected code in the models weight.

Ollama isn’t made by facebook, the llama models are. Ollama is juste a cli wrapper arround llama.cpp, both of which are FOSS projects.
