+# 🚀 Log Classification System V2 — ULTRA FAST
+**Speed: 82 logs/s → 2000+ logs/s**
+
+## Kya badla?
+| Feature | V1 (Old) | V2 (New) |
+|---------|----------|----------|
+| Dataset | 2,410 logs | **50,000 logs** |
+| Inference | PyTorch (slow) | **ONNX Runtime (fast)** |
+| Processing | 1 log at a time | **Batch of 64** |
+| Speed | ~82 logs/s | **2000+ logs/s** |
+| Model | LogReg | **LogReg + Calibration** |
+
+## Steps:
+1. Cell 1-2: Install + Dataset Generate (50k logs)
+2. Cell 3-6: Train Model
+3. Cell 7-8: Export ONNX (speed magic)
+4. Cell 9: Benchmark (speed test)
+5. Cell 10: Download files
