Amazon Opens Trainium Lab to Press — The Chip That Won Over Anthropic, OpenAI, and Apple
TechCrunch·high signal
TechCrunch received an exclusive tour of Amazon's Trainium lab shortly after AWS announced its $50 billion OpenAI deal committing 2 gigawatts of Trainium capacity. Project Rainier — a 500,000-chip Trainium2 cluster — already powers Anthropic's Claude at scale, with over 1 million chips total deployed for Anthropic. Apple is reportedly testing Trainium for AI workloads, positioning AWS custom silicon as the first serious structural threat to NVIDIA's near-monopoly on AI training and inference.
