Open weights are a defender’s advantage.
dfs-large1 from @depthfirstlabs matches frontier-model performance on vulnerability discovery and was built on the open GLM-5.2 model, post-trained with RL on @FireworksAI_HQ.
This is exactly the case for open-source AI policymakers need to notice: American companies can build best-in-class domain models using open weights.
Andrea Michi (@andreamichi): Today we’re announcing dfs-large1, our newest cybersecurity model that achieves best-in-class performance on vulnerability detection tasks.
Besides frontier AI labs, only a handful of companies have built specialized models that reach the state of the art in their domain. We’re
