Nous Research Team Releases Hermes 4: A Family of Open-Weight AI Models with Hybrid Reasoning

Nous Research has released Hermes 4, a family of open-weight models (14B, 70B, and 405B parameter sizes based on Llama 3.1 checkpoints) that achieves frontier-level performance through pure post-training techniques. Hermes 4 introduces hybrid reasoning – models can toggle between standard responses and explicit reasoning using <think>...</think> tags when complex problems require deeper deliberation.
