Magnum v4 72B

text->text

Magnum v4 72B is a community fine-tune. Behaviour and benchmarks track the upstream base model the fine-tune was trained from. Available via anthracite-org. 33K-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.

Magnum v4 72B is a efficient AI model from anthracite-org. It costs $3.000 per million input tokens and $5.000 per million output tokens (blended $3.600/M), with a 33K-token context window.

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.
