Summary
dfs-large1 is our most capable model to date, designed for vulnerability discovery and validation across large enterprise repositories. Built on GLM 5.2, it was post-trained inside depthfirst's security agent harness using our RL stack.
Why it matters
The release describes a concrete training and evaluation recipe for long-horizon AI code auditing, including repository-scale context, executable validation and explicit pressure against speculative findings.
