DeepSeek continues to not only push the boundaries but also publish these incredible papers explaining how they achieved their gains - something the American labs no longer do unfortunately. Chinese labs are doing the most interesting work in AI right now.
Publishing by necessity I wonder? American labs on the cutting edge pioneering the way forward, so Deepseek open sourcing what they’ve got is to help even the playing field. Hopefully the experts here can offer insight. The above is just my hunch and I’m not a specialist in this field.
It's more a cultural thing. Sharing progress is just in their blood.
