"Dangerous" AI models are coming no matter what

Summary

Anthropic's new Claude Fable 5 and Mythos 5 AI models were taken offline last week following a United States government export-control directive, which bars "any foreign national" from using the services. Anthropic had previously highlighted the dual-use nature of Mythos 5, noting its advanced capabilities for both identifying and exploiting software vulnerabilities. While Mythos 5 was released privately to Project Glasswing, Claude Fable 5, a model of similar grade, was made public with specific guardrails against biology and cybersecurity queries. The Trump administration ordered the restriction, citing national security risks due to concerns that Fable 5's guardrails could be disabled. However, experts like Tarah Wheeler and Bruce Schneier contend that such advanced AI capabilities are inevitable across the industry, with other companies and open-source developers likely to possess or soon develop similar models within 6 to 24 months, rendering the current restriction a temporary measure.

Key takeaway

For policy makers developing AI regulation, restricting specific advanced models like Anthropic's is a short-sighted approach. You should instead focus on creating comprehensive, transparent plans to manage the inevitable proliferation of dual-use AI capabilities across the industry within the next 6 to 24 months. Your efforts should prioritize developing broad frameworks that address the societal implications of widespread AI access, rather than attempting to contain individual technologies.

Key insights

Advanced, dual-use AI capabilities are inevitable across the industry, making single-company restrictions ineffective.

Principles

• Advanced AI capabilities are dual-use.
• Restricting one model is myopic.
• Existing AI can hunt vulnerabilities.

In practice

• Prepare for widespread advanced AI.
• Develop broad AI policy plans.
• Refine existing AI for vulnerability hunting.

Topics
