Google's Chrome team has been using AI to improve vulnerability discovery, triage, and patching, resulting in a significant increase in the number of security bugs fixed in recent Chrome releases. The team has developed AI-powered tools to find and fix security bugs, and has also improved its bug triage process. This has led to a substantial reduction in the time it takes to fix security bugs, with the team estimating that it is saving hundreds of hours of developer time per month. The use of AI has also enabled the team to find and fix bugs that may have gone undetected by human reviewers.
