OpenHermes 2
About
The OpenHermes family of large language models (LLMs) is based on the robust Mistral architecture, known for its enhanced performance across various benchmarks. Designed for tasks such as natural language understanding and generation, OpenHermes models excel in creative writing, analytical responses, and engaging open-ended conversations. They employ the ChatML prompt format to enable structured multi-turn dialogues, integrating system prompts for nuanced interactions. OpenHermes 2.5, a standout version, demonstrates significant improvements over previous iterations, particularly in following instructions and delivering human-like responses. While the models effectively handle diverse tasks, some feedback points to occasional verbosity in outputs. They are available in multiple quantized versions to suit different hardware and performance requirements, maximizing accessibility and adaptability.
