AVRI reportedly cuts costs for AI security bug-hunting agents

A post says 60.4% of tokens across 200 runs by four security bug-hunting agents went to understanding code and reasoning about how to trigger bugs. It describes AVRI as a tool that returns related code together and preserves links between program input and unsafe operations. On 20 new tasks, the post says AVRI cut total cost by 18.0% for Codex and 23.7% for OpenCode without lowering success or recall.
