+# Llama-3.1-8B-Breadcrumbs-v2
+This model is a 5-model integration utilizing the **Model Breadcrumbs** algorithm. 
+It merges `meta-llama/Llama-3.1-8B-Instruct`, `Magpie-Align/Llama-3.1-8B-Magpie-Align-v0.2`, `allenai/Llama-3.1-Tulu-3.1-8B`, and `deepseek-ai/DeepSeek-R1-Distill-Llama-8B`.
+## Hyperparameters
+* **Alpha ($lpha$):** 0.3 (Global Scaling)
+* **Beta ($eta$):** 0.9 (Drops bottom 90% of magnitude updates)
+* **Gamma ($\gamma$):** 0.99 (Drops top 1% of magnitude updates)
