The United States government announced that OpenAI’s next‑generation model, dubbed GPT‑5.6, will enter a limited preview phase, with each customer’s access subject to individual approval. The decision follows a recent pull of Anthropic’s Fable and Mythos models, marking the first time two of the sector’s biggest players face the same regulatory hurdle.
According to a report from The Information, the government’s review will continue "customer by customer" until a broader release receives clearance. OpenAI’s CEO Sam Altman has suggested the preview could last only a few weeks, but Anthropic’s Mythos has already lingered in preview for months with no clear timeline for a full launch.
Industry analysts say the added delay threatens the economic upside of costly new systems. AI labs are already under pressure to improve bottom lines, and a slowdown in model deployment could dampen demand for the massive data‑center capacity they are building.
Critics within the tech community have pointed fingers at both companies. Some accuse Anthropic of seeking regulatory capture, while others charge OpenAI with leveraging political connections to sideline rivals. The debate underscores how billions of dollars in stakeholder interest now hinge on the outcomes of these reviews.
Beyond corporate rivalry, the core issue is the lack of a clear, scalable process for evaluating frontier AI models. Government officials acknowledge the need for safety testing, but they lack the technical expertise and resources to conduct comprehensive assessments. As GMU fellow Dean Ball noted, regulators have not articulated the specific risks they aim to mitigate, leaving AI developers in a gray area.
Even as the review process raises concerns, experts point to tangible benefits of AI tools, such as advances in cybersecurity. The same regulatory scrutiny is appearing in related fields like biorisk and AI alignment, suggesting a broader push for oversight across high‑impact technologies.
Proposed solutions emphasize collaboration with independent bodies that can guide safety standards without favoring any single company. Advocates argue that the industry must rally around the most pragmatic regulatory options rather than fighting every rule.
What follows will test the AI sector’s ability to balance rapid innovation with public safety. The next few weeks will reveal whether the government’s approach can accommodate the pace of development while addressing legitimate risk concerns.
