Foundation-Sec-8B-Reasoning: First Open-Source AI Model for Cybersecurity Reasoning

Описание: DESCRIPTION:
Deep dive into Foundation-Sec-8B-Reasoning, the first open-source native reasoning model designed specifically for cybersecurity applications. Developed by Meta and Cisco's Foundation AI team, this groundbreaking model uses a two-stage training approach (Supervised Fine-Tuning + Reinforcement Learning with GRPO) to achieve exceptional performance on security tasks.

In this video, we cover:
The two-stage training pipeline (SFT + RL with GRPO algorithm)
SFT dataset composition: 2 million exemplars across cybersecurity, math, and science
How reinforcement learning sharpens reasoning accuracy
Solving reward hacking and format degradation challenges
Performance on 10 cybersecurity benchmarks (CTIBench, SecEval, MMLU-Security)
General-purpose capabilities maintained across 10 additional benchmarks
HarmBench safety evaluation with 98.25% pass rate using defense-in-depth
Ablation study: SFT vs RL contributions
Real-world applications: threat intelligence, vulnerability assessment, incident response

The model outperforms Llama-3.3-70B-Instruct (9x larger) on multiple security tasks while maintaining strong general capabilities. Built on Llama-3.1-8B architecture, it's completely open-source for security researchers and practitioners.
