Hermes 3
Open-weights fine-tune of Llama 3.1 built for agentic function calling.
Hermes 3 is an open-source model series by Nous Research fine-tuned on Llama 3.1 across 8B, 70B, and 405B parameters. It is trained primarily on synthetic data with an emphasis on following system prompts precisely, internal monologue reasoning, and multi-turn conversations. Its structured function-calling support makes it popular for building custom autonomous agents and workflows.
What it's for
- Power autonomous AI agents that invoke external APIs and tools
- Drive conversational workflows requiring strict adherence to system prompts
- Handle complex roleplay and internal monologue reasoning tasks
Features
- Fine-tuned versions across 8B, 70B, and 405B parameter scales
- Enhanced agentic function-calling capabilities
- Strong adherence to system instructions without heavy safety guardrail interference
- Long-term context retention across multi-turn conversations
- Open weights available on Hugging Face
Pricing
Open source. Free open-weights model; compute or hosting costs apply.
