OpenAI and Anthropic Restrict Access to Advanced AI Models Amid Regulatory Pressures
OpenAI and Anthropic are reportedly restricting access to their most advanced models as a strategic move to gain greater control over security, model distillation, and competing applications. This development comes amid pressure from U.S. regulatory bodies and reflects ongoing efforts by both AI labs to manage the implications of their cutting-edge technologies.
OpenAI’s latest GPT-5.6 models and Anthropic’s Claude Fable 5 and Mythos 5 have been subject to access limitations, with Anthropic previously disabling model access due to export-control concerns. The move aligns with a broader strategy to navigate the competitive landscape and address security challenges, potentially impacting revenue growth and valuation prospects.
