Claude Code rebuilds Projects for parallel multi-agent coding; Claude now leads 26% of Anthropic R&D

量子位 · wechat · 2026-09-18

Anthropic redesigned Claude Code Projects into a coordinator-driven multi-agent coding hub: a Coordinator breaks high-level goals into subtasks run by isolated cloud Claude Code instances on separate Git branches that auto-open PRs, with shared memory syncing decisions across threads; beta rolls out to some Pro/Max users. Alongside, Anthropic's new report says 26% of its internal R&D tasks now hit AL4 (AI end-to-end under loose oversight), up from <1% six months ago, with 30,000 concurrent agents, 1B+ monthly decisions (0.002% blocked by oversight), and 6% of R&D compute spent on safety.
