Anthropic’s Bombshell: 16 Million Queries, 24,000 Fake Accounts, Three Chinese AI Labs Anthropic went public Monday with an accusation that reads like a corporate espionage indictment: three Chinese AI laboratories — DeepSeek, Moonshot, and MiniMax — coordinated an industrial-scale attack designed to extract Claude’s capabilities by flooding the API with queries from fake accounts. The numbers in Anthropic’s official blog post are staggering: 16 million queries run through 24,000 fraudulent accounts using proxy services to obscure the traffic’s origin. The goal, Anthropic alleges, was model distillation at scale — using Claude’s outputs as training data to build competing models without paying the research costs. ...

Claude Cowork Goes Deep Enterprise: A Plugin Marketplace Built for the Office, Not the Lab Anthropic isn’t building a research tool anymore. With Monday’s launch of the Claude Cowork enterprise plugin marketplace, it’s making a direct play for the workflows that run actual businesses — the spreadsheets, the contracts, the HR systems, the design files. And the market took notice. Enterprise software incumbents felt the pressure — a signal that AI-native platforms are being taken seriously as competitive threats in corporate workflows. ...

Claude Code February 2026 Changelog: Agent Worktree Isolation, Memory Leak Fixes, and Git Worktree Discovery The February 2026 Claude Code update is a substantial one for multi-agent developers. Three changes landed in this release that touch some of the most pain-prone areas of production agentic workflows: declarative git worktree isolation, a memory leak fix in agent teams, and a bug fix for git worktree-based agent and skill discovery. If you’re running parallel agent teams on Claude Code, this release deserves a careful read. ...

Intuit and Anthropic Partner for Custom AI Agents in Mid-Market Finance — Spring 2026 Rollout The partnership that agentic AI practitioners have been waiting to see just became official. Intuit — the company behind QuickBooks, TurboTax, and Credit Karma — announced a multi-year partnership with Anthropic today that will bring customizable AI agents directly to mid-market businesses and everyday consumers. And buried in the press release is a detail that matters enormously for the developer community: Claude Code is already deployed across Intuit’s engineering organization. ...

Anthropic Releases Claude Sonnet 4.6 — 1M Token Context, Flagship Agentic Performance On February 17, 2026, Anthropic released Claude Sonnet 4.6, and the agentic AI community immediately took notice. This is the model that now powers OpenClaw by default — and for good reason. Sonnet 4.6 brings a 1 million token context window in beta, dramatically improved agentic task performance, and holds its price point at the same level as Sonnet 4.5. Flagship performance at mid-tier cost. ...

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. ...

Anthropic is extending Claude Code beyond code generation into active security work. Claude Code Security, now available in limited research preview via claude.com, scans entire codebases for vulnerabilities, validates findings to minimize false positives, and suggests human-reviewable patches. 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: ...
