We're launching Claude for Small Business, a package of connectors and ready-to-run workflows that put Claude inside the tools small businesses use every day.

Local Deep Research achieves ~95% on SimpleQA benchmark (tested with GPT-4.1-mini). Supports local and cloud LLMs (Ollama, Google, Anthropic, ...). Searches 10+ sources - arXiv, PubMed, web, and your private documents. Everything Local & Encrypted. - LearningCircuit/local-deep-research

Anthropic's response to the Secretary of War and advice for customers

Use Claude Code's autonomous agent loop with DeepSeek V4 Pro, OpenRouter, or any Anthropic-compatible backend. Same UX, 17x cheaper. - aattaran/deepclaude

Our latest model, Claude Opus 4.7, is now generally available. Opus 4.7 is a notable improvement on Opus 4.6 in advanced software engineering, with particular gains on the most difficult tasks.

Continue a local Claude Code session from your phone, tablet, or any browser using Remote Control. Works with claude.ai/code and the Claude mobile app.

Claude Sonnet 4.6 is a full upgrade of the model’s skills across coding, computer use, long-reasoning, agent planning, knowledge work, and design.

Anthropic is an AI safety and research company that's working to build reliable, interpretable, and steerable AI systems.

A federal judge in California has indefinitely blocked the Pentagon’s effort to “punish” Anthropic by labeling it a supply chain risk and attempting to sever government ties with the AI company, ruling that those measures ran roughshod over its constitutional rights.

Skills for threat modeling, scanning, triage, patching, plus an autonomous scanning harness you can /customize - anthropics/defending-code-reference-harness

Claude can now discover, learn, and execute tools dynamically to enable agents that take action in the real world. Here’s how.

Use channels to push messages, alerts, and webhooks into your Claude Code session from an MCP server. Forward CI results, chat messages, and monitoring events so Claude can react while you're away.

We’re launching The Anthropic Institute, a new effort to confront the most significant challenges that powerful AI will pose to our societies.

We’re upgrading our smartest model. Across agentic coding, computer use, tool use, search, and finance, Opus 4.6 is an industry-leading model, often by wide margin.
