You absolutely could. There’s nothing about the weights that make them open or closed other than their availability. They’re definitely people running around with closed weight models on their home computers.
What are you implying here? That someone has created their own LLM therefore they are running a closed weight model on their own computer? Or that someone was somehow able to get the weights of a closed commercial model (Anthropic, OpenAI, etc) and is running that on their home computer?
