+
+## Key Observations
+
+1. **Panini preserves semantic units** — Compare `nirapekza` (single token) vs `nirape##k##z##a` (4 noise fragments)
+2. **2-4x compression ratio** — Average 7.2 tokens vs 21.8 for Qwen2
+3. **No arbitrary byte-level splits** — No `##k`, `##z`, `##ab` noise
+4. **Grammatically-aligned boundaries** — Tokens match stems, endings, and compounds

+        ### About
+        
+        **Panini Tokenizer** uses recursive morphological analysis based on Pāṇinian grammar rules,
+        not statistical BPE. This results in:
+        
+        - ✅ **2-4x fewer tokens** for complex compounds
+        - ✅ **Semantically meaningful** token boundaries
+        - ✅ **No arbitrary byte-level splits** like `##k`, `##z`, `##ab`
