Trump administration to lift restrictions on Anthropic's Fable 5
Axios
—
The https://www.axios.com/politics-policy/donald-trump" target="_blank">Trump administration plans to lift export controls on Anthropic's Claude Fable 5 AI model as soon as Tuesday night, a U.S. official tells Axios.
Why it matters: The decision, eagerly awaited by AI developers, restores public access to the company's https://www.axios.com/2026/06/09/anthropic-mythos-class-safeguards" target="_blank">powerful Mythos-class model that had been pulled for security reasons 18 days ago.
Driving the news: Last week, the Trump administration allowed Anthropic to https://www.axios.com/2026/06/27/commerce-anthropic-mythos-restrictions-lift" target="_blank">restore access to Mythos 5 for a select group of government-approved organizations.
- Sources also https://www.axios.com/2026/06/27/anthropic-fable-5-return-soon" target="_blank">told Axios last week Fable 5 could return as soon as this week.
The big picture: The U.S. government's desired role in regulating and evaluating frontier AI models before release is still up in the air — creating an ad hoc regulatory environment for AI companies.
- It remains unclear what technical or policy changes Anthropic made to address Commerce Department concerns, particularly preventing access by foreign nationals.
- Commerce Secretary Howard Lutnick https://x.com/howardlutnick/status/2072100729603452965?s=46&t=lWeRdBU5epOoS27GJ8FHHg" target="_blank">said in a post on X that his office has "worked closely with Anthropic to analyze and approve Fable 5 to ensure alignment across the US Government and strengthen America's leadership in AI."
- OpenAI rolled out https://www.axios.com/2026/06/26/openai-gpt-sol-terra-luna-trump" target="_blank">GPT-5.6 only to a small set of approved customers last week after a https://www.axios.com/2026/06/25/trump-administration-openai-gpt-model-release" target="_blank">request from the U.S. government.
Threat level: U.S. officials, allies and leading AI companies have become increasingly concerned that frontier models could be misused to automate sophisticated cyberattacks or accelerate biological weapons development.
- At the same time, China is moving closer to https://www.reuters.com/legal/litigation/chinas-360-says-it-has-developed-tools-match-anthropics-mythos-2026-06-24/" target="_blank">producing its own Mythos competitor while continuing to release https://www.axios.com/2026/06/25/china-glm-52-open-source-hackers" target="_blank">open-weight models that rival models like Anthropic's Claude Opus 4.8.
What's next: The Trump administration faces an August deadline under a https://www.axios.com/2026/06/02/trump-signs-new-ai-executive-order" target="_blank">recent executive order to create standardized benchmarks for evaluating the security risks of new AI models.
