+# 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.
