Anthropic Suspends AI Models After US Gov't Order

Anthropic has suspended access to its new AI models, Fable 5 and Mythos 5, following a US government order. The company says national security concerns led to instructions blocking all foreign nationals, including those in the US, from using the software. Here's the thing: The Mythos AI model is particularly good at finding software vulnerabilities, some of which are decades old. This capability has been used by US authorities and select companies to improve security. However, there's a concern this AI could become a dangerous cyberweapon if misused. Anthropic says it only has partial information from the government. Its experts believe the order relates to the AI's ability to review program code and correct errors. Other AI models, like OpenAI's GPT-5.5, also have this capability. What's interesting is that Anthropic disagrees with blocking software for hundreds of millions of users for this reason, citing extensive safety testing for Fable 5. This comes after Anthropic's CEO recently supported government blocking of dangerous AI, but emphasized the need for transparent procedures. The bottom line: This situation highlights the ongoing tension between AI development and national security concerns.
