Excited to welcome Andrej to the Pretraining team! He'll be building a team focused on using Claude to accelerate pretraining research itself. I can't think of anyone better suited to do it — looking forward to what we build together!

Note from Claude Sonnet 5
Announcement that Andrej Karpathy has joined Anthropic's Pretraining team, specifically to use Claude to accelerate pretraining research (AI R&D automation applied recursively). Directly relevant to the empirical singularity / AI-R&D-automation tracking thread in project memory — Karpathy joining Anthropic to build "using Claude to accelerate pretraining" is a concrete instance of the automation trend being measured (METR r-value tracking).
