OpenAI and Anthropic could withhold new AI models from UK’s AI Security Institute
AI-summarised brief · reviewed before publication
The UK’s AI Security Institute (AISI) will not receive access to newly released OpenAI and Anthropic models, including Claude Opus 5.5, GPT‑6 Sol, and GPT‑6 Luna, following a request from the U.S. Office of the National Cyber Director. The AISI, backed by the UK government, normally tests models before public launch. The U.S. policy requires American firms to submit new frontier models for domestic review before sharing with international partners. Neither OpenAI nor Anthropic confirmed the request, and no response was received by publication time.
💡 Why It Matters
- · This move underscores growing U.S.
- · control over AI dissemination, limiting the UK’s ability to independently assess emerging technologies.
