depthfirst announced dfs-large1, a new cybersecurity model achieving best-in-class performance in vulnerability detection.
- Architecture & Training: Built on GLM-5.2 and post-trained with reinforcement learning (RL) inside depthfirst's security infrastructure. Large-scale RL compute was powered by Fireworks.
- Evaluation: Achieves state-of-the-art results on depthfirst-bench, a benchmark for long-horizon vulnerability discovery in complex repositories. The team notes training improvements have not plateaued.
- Availability: Currently available in preview within the depthfirst platform.
