GoKawiilAnthropic sped up Claude.ai and desktop app roughly 3x in two-week sprint
Anthropic engineers spent a two-week sprint in August optimizing four core user journeys in claude.ai and the Claude desktop app, which together account for 95% of user activity. Measured at the 75th percentile, load time for a fresh claude.ai page dropped from 3.1 seconds to 0.55 seconds, new Claude Code sessions went from 0.8 to 0.3 seconds, and Claude Cowork cloud sessions improved from 2.6 to 0.73 seconds, with a 3.1x average speedup across 13 measurements.
