Anthropic said the U.S. Commerce Department has lifted export controls on its Fable and Mythos artificial intelligence models, less than three weeks after the company was ordered to suspend access to its most advanced artificial intelligence models due to national security risks.
“We will begin restoring access tomorrow,” Anthropic said in a statement to X late Tuesday.
US authorities blocked access to the models on national security grounds several weeks ago, but in a letter to Anthropic seen by Reuters, US Commerce Secretary Howard Lutnick said export controls had been lifted and a license was no longer required to export them.
“Anthropic has agreed to proactively identify and address security risks associated with the models; work diligently with the US government on protocols, standards and releases for Mythos, Fable and future models; and inform the U.S. government of any harmful activity,” Lutnick said.
The United States has stepped up oversight of new artificial intelligence releases to identify potential threats amid concerns that advanced models that are fueling a boom in the sector and major capital investments could be misused by military intelligence users in China, Russia or other countries of concern.
Anthropic abruptly pulled the plug on its Mythos 5 and Fable 5 models following an export control order on June 12th. On Friday, the US government allowed Mythos 5 to be released to some “trusted” US organizations, partially reversing the order.
The US government’s review of which companies can access the models has drawn criticism.
OpenAI CEO Sam Altman said last week that extensive security testing “isn’t a bad idea. I just don’t like the idea of the government picking and choosing customers.”
ChatGPT maker OpenAI has delayed the full public launch of GPT-5.6 at the request of the US government, limiting access to it to a small group of trusted partners.
