The Pentagon officially labels Anthropic a security risk
The U.S. Department of Defense formally designated Anthropic’s Claude AI as a „supply chain risk.“ Consequently, no Pentagon projects are permitted to use Claude or its derivatives for at least the next year.
Claude now available in Microsoft Excel
Anthropic has introduced Claude for Excel, an AI assistant that can read, edit, and explain spreadsheets directly within Microsoft Excel. It can correct formulas and create new sheets.
Anthropic blocks OpenAI’s access to Claude
Anthropic has cut off OpenAI’s access to its Claude AI models after it was revealed that OpenAI had used them to compare performance with its own models ahead of the GPT-5 launch.
