+# Gemma-3-1B-IT BitsAndBytesConfig NF4 Quantized
+
+This model is a quantized version of `google/gemma-3-1b-it-qat-int4-unquantized` using BitsAndBytesConfig with NF4 quantization.
+
+## Model Details
+
+- **Base Model**: google/gemma-3-1b-it-qat-int4-unquantized
+- **Quantization**: BitsAndBytesConfig NF4 (4-bit)
+- **Quantization Type**: NF4 with double quantization
+- **Compute Dtype**: bfloat16
+- **Storage Dtype**: uint8
+
+## Quantization Configuration
+
+```python
+from transformers import BitsAndBytesConfig
+
+bnb_config = BitsAndBytesConfig(
+    load_in_4bit=True,
+    bnb_4bit_quant_type="nf4",
+    bnb_4bit_use_double_quant=True,
+    bnb_4bit_compute_dtype=torch.bfloat16,
+    bnb_4bit_quant_storage=torch.uint8
+)
+```
+
+## Usage
+
+```python
+from transformers import AutoModelForCausalLM, AutoTokenizer
+import torch
+
+# Load the quantized model
+model = AutoModelForCausalLM.from_pretrained(
+    "WaveCut/gemma-3-1b-it-qat-int4-bnb-nf4",
+    device_map="auto",
+    torch_dtype=torch.bfloat16,
+    trust_remote_code=True
+)
+
+tokenizer = AutoTokenizer.from_pretrained("WaveCut/gemma-3-1b-it-qat-int4-bnb-nf4")
+
+# Generate text
+inputs = tokenizer("Hello, how are you?", return_tensors="pt")
+outputs = model.generate(**inputs, max_length=100)
+response = tokenizer.decode(outputs[0], skip_special_tokens=True)
+print(response)
+```
+
+## Benefits
+
+- **Reduced Memory Usage**: ~75% reduction in memory footprint compared to full precision
+- **Faster Inference**: Optimized for inference speed
+- **Maintained Quality**: NF4 quantization preserves model quality effectively
+
+## Hardware Requirements
+
+- **GPU Memory**: ~3-4GB VRAM (vs ~12GB for FP16)
+- **CUDA Compatible**: Requires CUDA-capable GPU for optimal performance
+- **CPU Fallback**: Can run on CPU with reduced performance
+
+## Quantization Details
+
+This model uses BitsAndBytesConfig for 4-bit quantization:
+- NF4 (Normal Float 4) quantization for optimal quality/size trade-off
+- Double quantization for additional compression
+- Mixed precision with bfloat16 compute dtype
+
+## License
+
+This model inherits the Apache 2.0 license from the base model.
