+## 🚀 What’s New?
+
+> **TL;DR** – Think of this model as the beefed-up, protein-shake-powered sequel to **MasterControlAIML/DeepSeek-R1-Qwen2.5-1.5b-SFT-R1-JSON-Unstructured-To-Structured** … except we ditched the SFT and let a squad of reward functions do the coaching.
+
+### Key Upgrades
+1. **Larger Backbone** – We jumped from a 1.5 B parameter model to a 3 B parameter **Qwen 2.5** variant for more representational oomph.  
+2. **No SFT, All 🍬 Rewards** – Instead of supervised fine-tuning, training relied solely on reward-based optimization (GRPO).  
+   - **LM-as-Judge**: A language model scored candidate outputs for task quality.  
+   - **Auxiliary Rewards**: Style, length, and JSON-validity rewards kept the model on its best behavior.  
+3. **2× Faster Training** – Courtesy of Unsloth’s memory-efficient tricks (flash attention + fused optimizers).  
+
+---
+
+## 🛠️ Intended Use
+
+- Converts messy, free-form text into structured JSON—exactly like its 1.5 B predecessor, but with a deeper knowledge reservoir and reinforcement-tuned precision.  
+- Drop-in replacement for any pipeline already using the DeepSeek-R1 model. Just swap checkpoints and enjoy the headroom.

+
+## 🏋️ Training Details
+
+| Item | Value |
+|------|-------|
+| **Base Model** | `unsloth/Qwen2.5-3B-Instruct` |
+| **Batching** | Gradient Accumulation 8, bfloat16 |
+| **Optimizer** | AdamW (fused) |
+| **Algorithm** | GRPO (policy ≈ LM; reward model ≈ separate LM judge) |
+| **Epochs** | 3 (effective) |
+| **Speed** | ~2× faster vs. vanilla PyTorch thanks to Unsloth |
+
+---
+
+## 📊 Evaluation (Coming Soon)
+
+We’re benchmarking against:
+- Exact-match JSON accuracy  
+- Structural F1  
+- Valid-JSON rate  
+
+…stay tuned—numbers arriving faster than you can say “schema validation.”
