What WebLLM Chat actually is

Chat with an open-weights model that downloads once and then runs entirely inside the browser through WebGPU. Nothing is sent to a server, so it carries on working with the network switched off. The first load is a large download, after which replies generate locally.

Why it is worth your time

Disconnecting from the internet mid-conversation and watching it keep answering is the moment local inference stops being an abstract claim.
