OpenAI CEO Sam Altman has publicly applauded competitor DeepSeek’s R1 model in a recent social media post.

Since then, Musk hasn’t hidden his anger with Altman and OpenAI.

All of which is why the past week has been hilarious.

OpenAI chief executive Sam Altman has welcomed the debut of DeepSeek’s R1 model and has promised to deliver better AI models.

SoftBank, OpenAI, and Oracle are launching a $500 billion joint venture named Stargate to fund AI infrastructure in the U.S. The initiative, praised by President Trump, aims to deploy $100 billion immediately for projects like data centers and cancer research.
