Anthropic restricted its most powerful model over cybersecurity fears. Meta abandoned open source for its flagship release.

OpenAI closed a $122 billion funding round at an $852 billion valuation. Oracle cut 30,000 jobs to redirect billions toward AI infrastructure. And Eli Lilly placed a $2.75 billion bet on AI-powered drug discovery.

The GTC 2026 dominated the news cycle with new chips, a new rack architecture and an open platform for AI agents, which brought 17 major enterprise partners on board on day one.
