Hermes 4.3
Hermes 4.3 is an updated flagship in the Hermes line, trained to balance strong reasoning with practical deployment. Built on ByteDance’s Seed-OSS-36B base, it extends context length to roughly 512k tokens and is aligned to answer more questions while respecting user values, achieving state-of-the-art scores on RefusalBench among non-ablated models. The model targets local and self-hosted setups where users want near-frontier quality without depending on closed APIs.
Overview
Hermes 4.3 is Nous Research’s 36B hybrid reasoning model, based on Seed-OSS-36B, offering long context (up to 512k) and very high helpfulness on RefusalBench while staying locally deployable.
