Thariq Shihipar, a lead engineer on Anthropic’s Claude Code team, announced his departure after over a year scaling the AI coding tool, calling it his most fun yet stressful job. Anthony Morris, creator of the Claude Code desktop app, shared that yesterday was his last day, joking about time for GTA VI after thanking users for their input. Both left positive notes amid Anthropic's IPO preparations and chatter about Opus 5.5 performance, with colleagues like Lydia Hallie expressing they'll miss Shihipar's inspiration.
