HOW WE MADE CLAUDE.AI 3X FASTER IN TWO WEEKS

Summary from the TLDR newsletter

Anthropic made the core user experience of claude.ai and the Claude desktop app about 3x faster during a two-week sprint in August. Time to a typeable page on a fresh load of claude.ai went from 3.1 seconds to 0.55 seconds, starting a new Claude Code session went from 0.8 seconds to 0.3 seconds, and loading a Claude Cowork cloud session went from 2.6 seconds to 0.73 seconds. The optimizations will likely save an estimated tens of thousands of user-hours of waiting every day. This post covers what the Claude team shipped, how they measured it, and the loop they built with Claude to do it safely.
