Google's AI Fixed 1,072 Chrome Security Bugs in One Month

Google fixed 1,072 security bugs in June using AI, surpassing the total of the previous two years combined. The author details the automated engineering architecture Google built around the model:
- Knowledge Base: Integrates a database of every known Chrome CVE and the entire Git history.
- Security Assumptions: Leverages SECURITY.md files to document each component's security prerequisites.
- Multi-Agent Collaboration: Uses a Critic Agent with its own context to loop with a Fixing Agent, mimicking human code review.
- Redundancy & Testing: Runs multiple passes over the same code to catch missed bugs, alongside test-writing agents that verify fixes across all Chrome platforms before developer involvement.
This system even uncovered a sandbox escape vulnerability that had survived in the codebase for over 13 years. The author argues that AI has become scarily good at coding, signaling the end of manual code reviews.
