Story summary

In early talks this year, Dario Amodei's Anthropic and Sam Altman's OpenAI were negotiating a legally binding deal to stress-test each other's AI models for potential safety flaws. The discussions came before the high-profile incident where OpenAI accidentally hacked rival firm Hugging Face. Lawyers were drafting terms that would involve both companies subjecting their new AI models to rigorous testing, aimed at identifying hidden dangers and flaws. However, it is unclear if this agreement was ever finalized. This development follows recent calls for peer review among leading AI labs from notable figures like Elon Musk, who advocates for mutual testing between US and Chinese labs to ensure AI safety. The debate intensified after a 27-year-old former employee of both companies warned that major AI firms are "gambling with our lives" by advancing technology too quickly without proper safeguards.
