Google, OpenAI, and Meta have all joined the open-source camp. Previously, Elon even retweeted Jensen Huang's post to show support—looks like xAI might sign on soon too. Then Julian Schrittwieser, the core tech guy at Anthropic, said, 'So excited, turns out Jensen Huang is now supporting open source! Looking forward to seeing CUDA and GPU drivers released as open source.' Sounds pretty reasonable, right? But actually, the open letter is calling on governments not to ban open models. Julian sarcastically asked, 'Then why don’t you open source all your core products?' Supporting open-source models doesn’t mean everything has to be open source. These are two different things!
