Anthropic says a March 4 Department of War letter designates it as a supply chain risk, but argues the scope is narrow and will challenge the action in court.

On January 13, 2026, Anthropic announced an expanded Labs organization focused on experimental Claude products. The company is formalizing a two-track model: fast frontier experimentation and separate operational scaling for reliable customer-facing products.

In a January 21, 2026 engineering post, Anthropic explained how it repeatedly redesigned a take-home performance test as Claude models improved. The company describes how Opus 4 and Opus 4.5 changed the evaluation baseline and forced process-level updates.

Anthropic published a Frontier Safety Roadmap that outlines dated goals across security, safeguards, alignment, and policy. The document pairs current ASL-3 protections with milestone targets through 2027, including policy proposals and expanded internal oversight.

Anthropic posted that Opus 3, after retirement interviews, will continue sharing its reflections via a Substack blog for at least the next three months. The update points to an ongoing public publishing format rather than a one-off model announcement.

Anthropic published Responsible Scaling Policy Version 3.0 on February 24, 2026. The update keeps the ASL framework but retools how commitments are managed when capability thresholds are hard to measure unambiguously.

Anthropic says distillation attacks against Claude are increasing and calls for coordinated industry and policy action. In an accompanying post, the company reports campaign-level abuse patterns and outlines technical and operational countermeasures.

Anthropic's Claude iOS app shot to number one on the US App Store as users switched from ChatGPT in solidarity with Anthropic's decision to refuse Pentagon military surveillance requests.

Anthropic announced it will legally challenge the Pentagon's supply chain risk designation, issued after the company refused to assist with military surveillance programs. It's an unprecedented move for an AI company against the federal government.

The US Treasury Department announced it will terminate all use of Anthropic AI products following Trump's executive order designating Anthropic as a supply chain risk after the company refused military surveillance assistance.

Anthropic launched Claude Cowork plugins that embed Claude natively into Microsoft Excel, PowerPoint, Slack, Gmail, and Google Drive—enabling autonomous cross-app workflows for enterprise users.

After Trump ordered federal agencies to stop using Anthropic AI, the Pentagon designated the firm a national security supply chain risk—and OpenAI secured a competing Defense Department agreement within hours.
