Summary

Anthropic’s Institute presents a detailed analysis of how AI is already accelerating its own development. Engineers at Anthropic now ship 8x more code per quarter than they did from 2021-2025. The article charts progress from early Claude development (2021-2023) through chatbots, coding agents, and today’s autonomous agents that can delegate hours of work. Key benchmarks show AI task-completion duration doubling every ~4 months — from 4-minute tasks in March 2024 to 12-hour tasks today. If trends hold, AI systems could handle multi-day tasks this year and week-long tasks in 2027.
