What changed?
- 1Released 100 new tasks covering 91 different CWEs.
- 2Introduced deterministic, programmatic grading for reproducible results.
- 3Implemented a 'held-out' set to prevent model contamination.
- 4Added support for running benchmarks directly via the Harbor CLI tool from the Hugging Face repository.
Why it matters
This release provides a rigorous, objective standard to measure the security-patching capabilities of your LLM-based agents, moving beyond simple code generation to functional, secure development.
What it means for AI agents and contact centers
For your engineering teams, this is a vital benchmark to test your agents' defensive coding capabilities. Compare how your models perform against leaders like Gemini 4 Argon or Claude Opus 5.5 in terms of both pass rates and cost-efficiency to optimize your deployment strategy.
🧪 Worth Testing
It is a reliable way to quantify the effectiveness of your agents in a real-world, sandboxed development environment before production deployment.
