On 12 June 2026, Anthropic announced that the US government had ordered it to suspend access to Fable 5 and Mythos 5 for any foreign national, “whether inside or outside the United States”, including Anthropic’s own foreign-national employees. The company said it had therefore disabled both models for all customers while it worked out how to comply. This was not an ordinary country-based export restriction. It was a citizenship-based restriction on access to some of the most capable AI systems yet released by an American company.
That decision looks crude, and it is. But it becomes less mysterious when read alongside Anthropic’s own numbers. In its Institute essay on recursive self-improvement, Anthropic says that by the second quarter of 2026 its typical engineer was merging eight times as much code per day as in 2024. The broad point is obvious: this is no longer merely a better autocomplete. It is the beginning of a multiplier.
