What is Hermes-3-Llama-3.1-405B?

Hermes-3-Llama-3.1-405B is the flagship model in the Hermes series developed by Nous Research. It represents a full parameter finetune of the Llama-3.1 405B foundation model, designed to provide advanced language understanding and generation capabilities. The model implements ChatML format and offers exceptional performance in multi-turn conversations, reasoning, and specialized tasks like function calling.

Implementation Details

The model utilizes BF16 tensor type and requires significant computational resources - over 800GB of VRAM in FP16 format. To address this, a pre-quantized FP8 version is available requiring only 430GB of VRAM. The model supports both standard inference through Hugging Face Transformers and optimized inference through VLLM.

  • Supports ChatML format for structured dialogue
  • Implements advanced function calling capabilities
  • Offers JSON mode for structured outputs
  • Compatible with various quantization methods (4-bit, 8-bit, FP8)

Core Capabilities

  • Advanced agentic capabilities and reasoning
  • Enhanced roleplaying abilities
  • Improved multi-turn conversation handling
  • Long context coherence
  • Structured output generation
  • Function calling with precise control
