OpenAI and Anthropic are now at the mercy of the same government review process

openai's gpt 5.6 and anthropic's mythos models are reportedly stuck in government-mandated limbo, requiring case-by-case federal approval for release in a move that mirrors the recent block on anthropic's fable and mythos models. this strict review process lacks clear safety standards or government capacity for evaluation, creating uncertainty that could flatten revenue growth and chill the aggressive data center buildout driven by ai demand. the new reality impacts both leading labs equally, rendering old rivalries less relevant than the collective challenge of navigating a regulatory environment that lacks defined risk parameters. industry experts suggest the sector must coalesce around standardized evaluations and independent oversight to prevent arbitrary restrictions from halting progress entirely.
