Nous: Hermes 4 405B

text->text

Nous: Hermes 4 405B is a community fine-tune. Behaviour and benchmarks track the upstream base model the fine-tune was trained from. Available via nousresearch. 131K-token context. Mid-tier pricing. Inherits weights from an upstream open-weights base; benchmarks track the base model unless the fine-tuner publishes their own.

What it's good at
  • Persona/tuning beyond the base model
  • Persona/style adherence beyond the base model
  • Specific domain (RP, instruction, etc.) tuning
  • Inherits base-model capability
Typical use cases
  • Roleplay and creative chat
  • Domain-specific assistants
  • Custom persona deployments
Benchmarks
No published benchmark scores tracked for this model yet. Frontier and reasoning models from major providers have scores; smaller models and inference-host variants typically inherit the underlying open-weights score.
