Overview

• Patil started earlier this week, succeeding co‑founder Sam McCandlish, who becomes chief architect focused on pre‑training and large‑scale model training.
• Both Patil and McCandlish will report to Anthropic president Daniela Amodei.
• As CTO, Patil will oversee compute, infrastructure, inference, and broader engineering operations.
• Anthropic is restructuring its core technical group to bring product engineering into closer contact with infrastructure and inference teams.
• The changes follow heavy Claude usage that led to July caps on Claude Code (240–480 weekly hours for Sonnet and 24–40 for Opus 4) and intensifying infrastructure competition highlighted by TechCrunch, including Meta’s stated $600 billion U.S. spend through 2028.
