Anthropic Disables Fable 5 and Mythos 5 Due to US Export-Control Directive

On June 12, 2026, Anthropic announced the abrupt disabling of its AI tools, Fable 5 and Mythos 5, due to a US export-control directive. This decision affects all customers relying on these models for AI applications. The announcement follows the Local-First Conf held in Berlin on July 13, 2026, where many attendees utilized Claude Code, a tool that demonstrates the growing reliance on LLMs despite criticisms. Armin Ronacher, founder of Earendil, highlighted that LLMs often ‘auto-close almost all PRs and issues,’ indicating a significant dependency on these models in software development. Earendil’s mission emphasizes that ‘humans are the best agents’ in an AI-driven world, reflecting a tension between reliance on AI and the need for human oversight. Martin Kleppmann noted that ‘the probability of a conflict between Europe and the US is still very low,’ suggesting a stable environment for AI development despite regulatory challenges. This incident underscores the fragility of AI tool availability in the face of geopolitical regulations, impacting developers’ strategies for integrating AI into their workflows.
