Hermes 3 & Hermes 4 Open Weights

Frontier Open Weights Models

Overview & Capability

Generalist, steerable, uncensored language models built on Llama and customized architectures. Renowned for superior roleplaying, complex multi-step reasoning, and strict adherence to structured JSON schemas.

Key Highlights

  • Available in 8B, 70B, and 405B parameter sizes for laptop to multi-GPU setups.
  • Advanced function calling capabilities built directly into model pretraining.
  • Run locally in 1 click using `ollama run nous-hermes`.
Robbie's Independent Take Verified: 2026-10-11

Excellent candidate for local execution with zero cloud lock-in. For 7B-8B parameter models, budget at least 8 GB of unified memory or VRAM (Q4_K_M quantization). For 32B-70B models, aim for 24 GB+ to maintain interactive throughput without CPU offload penalties.

Alternatives & Replaces

  • Proprietary closed-source API dependencies
