GoKawiilOpen-weight AI models explained: what downloadable weights let you do
CNET published an explainer describing open-weight AI models, which let users download a pretrained model's neural network weights and run their own copy locally rather than relying on a provider's servers. The piece contrasts these with closed models like ChatGPT and Claude, whose weights remain private, and quotes Mistral's VP of science, Pierre Stock, noting that once weights are released they spread across sites like Hugging Face and become nearly impossible to pull back.
