# Hermes 3

Canonical: https://www.softwareadvice.co.uk/software/630612/Hermes-3

> Hermes 3 is a series of instruction-following and tool-use language models built for researchers, open-source developers, and technical practitioners across AI research, agentic application development, code generation, and creative writing. The models are available in three sizes (8B, 70B, and 405B parameters) and can be self-hosted via HuggingFace or accessed through the Nous Portal and compatible third-party endpoints.

Core features include a 128K token context window for long-term multi-turn conversations, structured multi-step reasoning using internal monologue tokens, and function-calling via JSON schema-defined tools. Hermes 3 also supports retrieval-augmented generation with structured citation tags, Mermaid diagram generation, and complex roleplaying and creative writing tasks.

Teams building agentic pipelines benefit from out-of-the-box tool use, planning, and external data integration. The highly steerable system-prompt design lets developers shape model behavior and persona without the instruction refusals common in closed commercial models. Support is available through community resources and documentation on HuggingFace.
