- Claude Fable 5 is back after the US government imposed emergency export controls due to concerns over its cybersecurity use.
- The model is available again through Claude.ai, Claude Code, Claude Cowork, and its API after restrictions were lifted on June 30.
- Anthropic is tightening efforts to block unauthorized access to its artificial intelligence services from China after identifying methods used by Chinese companies to bypass its restrictions.
- Anthropic added a new classifier to Claude Fable 5 that redirects requests aimed at uncovering software vulnerabilities to the older Claude Opus 4.8 model.
- Ant Financial has accessed Anthropic's Claude AI tools through overseas subsidiaries, cloud providers and other workarounds.
- Ant Financial provided employees with corporate Claude accounts linked to its Singapore-based entity, while ByteDance reimbursed engineers for personal Claude subscriptions accessed using virtual private networks (VPNs).
- The practices reportedly do not violate U.S. or Chinese law but breach Anthropic's terms of service, which prohibit Chinese companies and foreign entities under their control from using its AI models.
- Anthropic has stepped up efforts to detect and shut down unauthorized access, including monitoring accounts for indicators such as users' computer time zones.
- Some companies accessed Claude through foreign subsidiaries using cloud infrastructure, including Microsoft's Azure platform.
- Anthropic will continue to work with government agencies as it prepares future frontier models for release.
Claude Fable 5 has returned to availability following the U.S. government's decision to lift export controls on June 30, which were initially imposed due to concerns over cybersecurity applications. The model is now accessible via Claude.ai, Claude Code, Claude Cowork, and its API.12479
In response to unauthorized access attempts, Anthropic has tightened its security measures, particularly against Chinese firms exploiting loopholes. Reports indicate that companies like Ant Financial and ByteDance have utilized overseas subsidiaries and cloud services to access Claude AI tools, circumventing restrictions.3568
Anthropic has developed a new classifier designed to detect prompts aimed at exploiting software vulnerabilities, successfully blocking over 99% of reported bypass techniques. The company is actively monitoring accounts for compliance, focusing on indicators such as users' computer time zones and targeting services that relay requests through foreign accounts.
While these practices do not violate U.S. or Chinese law, they breach Anthropic's terms of service, which prohibit access by Chinese companies and foreign entities under their control. The company continues to collaborate with government agencies as it prepares for future model releases.
“Claude Fable 5 has returned following the lifting of US export controls. Meanwhile, Anthropic is addressing unauthorized access by Chinese firms to its AI services.”
