Anthropic Powers Developers With Claude Opus 4.5

Anthropic released Claude Opus 4.5 in November 2025, powering desktop tools Claude Code and Cowork that perform autonomous coding and file tasks. Users and executives report dramatic productivity gains—some completing year-long projects in days—and Anthropic's audience and enterprise market share surged, with daily desktop visitors up 12% year-to-date and pricing at $5/$25 per million tokens. Enterprises are integrating the agents while raising security and hiring implications.
