Description

NousResearch's official post-training dataset behind the Hermes model line. Couldn't find a standalone public dataset release specific to Hermes 4 (its ~5M-sample corpus appears to ship only as trained checkpoints, not a separate downloadable dataset) — this is the closest confirmed real one.
