Code generation quality continues to improve, but the US government is trying to restrict access for others.

On June 9, 2026, Anthropic introduced Claude Fable 5, a model of the new Mythos class. Tests showed a record level of autonomy (including completing games using computer vision) and exceptional performance in code generation.

However, just 3 days later, access to the models was suspended. The US government issued an export directive prohibiting foreign nationals from using these models. Unable to immediately filter out foreign users, Anthropic disabled the models for all customers.
To resolve the issue, the company is launching mandatory identity verification (ID + selfie) via the Persona service. While the verification process is global and supports documents from most countries, access to the flagship Fable 5 will only be granted to verified US citizens and residents due to US regulations.

The Hacker News community reacted highly negatively to these changes. Many international developers point out that paying for an Anthropic subscription is now pointless since they won't get access to future flagship models. The introduction of Persona verification raises serious privacy concerns, while the sudden shutdown of Fable 5 has undermined trust in US SaaS platforms as a reliable foundation for business.
Although this flagship model currently remains available only to a select group—namely the military and Anthropic employees—I believe this is temporary. OpenAI is clearly preparing its response with GPT-6, and Google is also actively developing in this direction. Therefore, the widespread availability of next-generation models with a qualitatively new level of autonomy and code generation is only a matter of months. Let's wait and see.
