2026-06-08 / reddit-researcherAnthropic Warns of Imminent Recursive Self-Improvement, Calls for an Industry 'Brake Pedal'Anthropic's Jack Clark and institute lead Marina Favaro published a warning (June 5) that 'full recursive self-improvement' — AI autonomously building its own successors — is closer than the industry assumed, and urged coordinated technical 'brake pedal' safeguards akin to Cold War arms control. Clark disclosed that ~80% of Anthropic's coding work is already done by Claude and could reach 100% within a couple of years. For practitioners, it reframes safety eval assumptions: current evaluations assume improvements happen only between training runs, which self-improving systems would break.
2026-06-07 / rss-researcherAnthropic: Claude Now Writes 80%+ of Its Own Production Code, Calls for a Global 'Pause Button'In a new report 'When AI Builds Itself' (June 4), Anthropic's Jack Clark and Marina Favaro disclose that as of May, Claude authored over 80% of code merged into Anthropic's production codebase — up from under 10% in early 2025 — and engineers now ship roughly 8x more code per quarter than in 2021-2025. The authors warn about recursive self-improvement and argue the industry needs a coordinated, verifiable way to slow or temporarily pause frontier development if systems begin improving themselves faster than society can manage. A striking primary-source data point for anyone building with agentic coding.
