Anthropic Releases Opus 4.6 To Enhance Coding

Anthropic releases Opus 4.6, a direct upgrade to its Claude models, aiming to improve speed and precision for agentic coding and long-horizon tasks. The release follows a holiday surge in Claude Code use — Anthropic reported Claude Code passed $1 billion in revenue in November 2025 and Caliber measured a 13 percentage point word-of-mouth spike between Dec. 29 and Jan. 26. Opus 4.6 seeks to consolidate recent gains and broaden enterprise adoption.
