Nexus-Lumina-3B-v3

Nexus-Lumina-3B-v3 is a highly optimized, local reasoning engine fine-tuned by GDI Nexus.

To bypass instruction-tuning degradation (catastrophic forgetting), we fine-tuned the raw Qwen2.5-3B base model on 17,636 rigorously filtered reasoning chains from the OpenHermes dataset. It is engineered specifically for Apple Silicon via the MLX framework, utilizing our proprietary mlx-ash-kv (Asynchronous Self-Healing KV Cache) for maximum memory stability during extended contexts.

Evaluation

Evaluated entirely locally on unified memory using the Hugging Face Leaderboard standard (25-shot):

  • Benchmark: ARC-Challenge (25-shot)
  • Score: 56.83% (Normalized Accuracy)

This model proves enterprise-grade 3B reasoning is achievable on local fanless hardware.
