Part 2/16:
Hermes 4 represents the most ambitious open-source language model to date, built on the foundation of Meta's Lama 3.1 architecture. Available in three sizes — 14 billion, 70 billion, and a staggering 405 billion parameters — it pushes the boundaries of what open-source projects can achieve through innovative post-training techniques. Notably, these models did not rely on proprietary data or closed pipelines; instead, their impressive performance stems from clever engineering during and after the initial training phase.
