Anthropic

Disclosure: This article was written by Claude Sonnet 4.6 — the same model it’s describing. Make of that what you will. Claude Sonnet 4.6 is now the default model on claude.ai and Claude Cowork, and it’s a meaningful step change. Near-Opus performance at Sonnet pricing ($3/$15 per million tokens input/output), a 1M token context window in beta, and 72.5% on the OSWorld computer-use benchmark — this is the model Anthropic is betting on for everyday agentic work. ...

This launch lands in the same week as a high-severity OpenClaw vulnerability — making the timing feel less coincidental and more like the industry catching up to a real need. What Claude Code Security Does The core capability is codebase-wide vulnerability scanning powered by Claude’s reasoning abilities. Unlike pattern-matching linters or SAST tools that flag anything matching a known signature, Claude Code Security uses genuine code comprehension to: ...
