Anthropic confirmed on Wednesday that it is building an in-house silicon team, hiring engineers who have taken chips from concept to production to co-design custom hardware and Claude models so they run faster and more efficiently at customer scale. It is the company's first public confirmation after months of reports, including talks with Samsung over a 2-nanometer part. Anthropic says custom silicon adds to — not replaces — its mix of Amazon, Google, Nvidia and AMD hardware, and gave no timeline.
