SAN FRANCISCO, July 1, 2026 (AP) — The Trump administration has lifted restrictions on artificial intelligence company Anthropic's latest versions of its Claude chatbot, ending a weekslong ban tied to [cybersecurity concerns](https://apnews.com/article/trump-ai-openai-gpt56-sol-cybersecurity-mythos-065d5398baac7f16c8265c2cb8ba2baa?ref=broadbandbreakfast.com).

Anthropic said Tuesday night that its AI model called Claude Fable 5 is now widely available. It's also restoring access to its most powerful model, Mythos 5, but only to a select group of U.S.-based organizations approved by the federal government.

The Commerce Department blocked foreign nationals from using both AI models on June 12, a move that San Francisco-based Anthropic said forced the company to immediately [take the products down](https://apnews.com/article/anthropic-trump-fable-mythos-tech-0a87a0f7773255419936af053ad8bdef?ref=broadbandbreakfast.com) for all users just days after it unveiled them.

Anthropic said in a blog post this week that the government's concerns were sparked by a report from cybersecurity researchers at Amazon, Anthropic's primary cloud computing provider. The company “had found a method of bypassing Fable 5’s safeguards” that enabled it to discover and potentially exploit software vulnerabilities, Anthropic said.

Officials have grown increasingly concerned since [Anthropic](https://apnews.com/article/anthropic-artificial-intelligence-ai-938c99158e5953601cf3322f1cec12af?ref=broadbandbreakfast.com) warned earlier this year that its Mythos model was adept at finding software flaws in a way that could be weaponized by malicious hackers and threaten critical computer networks around the world.

Anthropic's chief rival, ChatGPT maker [OpenAI](https://apnews.com/hub/openai-inc?ref=broadbandbreakfast.com), also said Friday it is restricting the release of its new artificial intelligence model at the request of President Donald Trump’s administration.

OpenAI said its new AI product, called GPT-5.6 Sol, would be accessible only to a select group of government-approved customers for a temporary period.

Trump last month signed [an executive order](https://apnews.com/article/trump-ai-executive-order-e41af74f7b0865482f07d10fe7a50fe3?ref=broadbandbreakfast.com) on AI oversight that established a framework for the federal government to vet the national security risks of the most advanced [AI systems](https://apnews.com/hub/artificial-intelligence?ref=broadbandbreakfast.com) for up to 30 days before their public release. The order described participation by AI developers as voluntary, but the framework has not yet been fully developed.
