Anthropic announced on June 12 that US authorities had ordered it to restrict access to its AI models, citing national security concerns.

But, in a surprising turn of events, the US government has now lifted the export ban, allowing the company to resume access to its advanced AI tools.

Anthropic said in a statement that it will begin restoring access to Claude Fable 5 and Mythos 5 on Wednesday after being notified that the US Department of Commerce has lifted restrictions on the two models.

The Commerce Department said in a letter seen by the BBC that Anthropic has addressed the risks associated with its AI models. "Anthropic has agreed to proactively detect and address security risks associated with the models," Commerce Secretary Howard Lutnick wrote in a letter to the tech company.

The firm has also agreed to collaborate on future releases of its AI models and alert the government of any malicious activity, Lutnick wrote.

Mythos and Fable are two of Anthropic's AI models built on its Claude platform – a rival to the likes of OpenAI's ChatGPT and Google's Gemini.

Fable 5 is a version of the AI model for the consumer market, capable of deep reasoning and can perform complex tasks independently.

Mythos 5, on the other hand, is a version of the platform designed for businesses and cybersecurity experts.

It is said to be able to identify vulnerabilities in computer code and exploit them. Both models were released on 9 June.

The US government's decision to lift the ban comes as a relief to Anthropic, which has maintained that its AI models are safe and pose no national security risks.

The company had argued that the ban was unjustified, particularly since it had not pinpointed specific concerns about its technology. "Our understanding is that the government believes it has become aware of a method of bypassing, or 'jailbreaking' Fable 5," the company said at the time. "However, we disagree that the finding of a narrow potential jailbreak should be cause for recalling a commercial model deployed to hundreds of millions of people," Anthropic said.

With the ban lifted, Anthropic can now continue to develop and deploy its advanced AI tools, which have the potential to revolutionize various industries such as healthcare, finance, and education.

The company's decision to collaborate with the government on future releases of its AI models also marks a significant step forward in ensuring the safety and security of its technology.

As the use of AI continues to grow, the need for robust safety and security measures becomes increasingly important.

With Anthropic's commitment to collaboration with the government, the possibility of another ban is reduced, and the company can focus on making its AI technology more accessible and beneficial to society.

The full impact of this decision remains to be seen, but one thing is certain – AI is here to stay, and the world will be watching Anthropic closely as it continues to innovate and push the boundaries of what is possible.
