Open Models · From my video notes
DeepSeek went open. Here is how to use it.
The link list behind my video on DeepSeek open-sourcing DeepInfer. Four gains for ordinary users: free chat, a cheap API, downloadable weights, and local inference on your own hardware. Every link is official or the project's own repo.
