🚀 Usage

Python (Server/Desktop)

from transformers import AutoModelForCausalLM, AutoTokenizer
import torch

# Load model
model = AutoModelForCausalLM.from_pretrained(
    "bhismaperkasa/gemma-3-1B-it-form-generator-q4_4096",
    torch_dtype=torch.bfloat16,  # Use BF16 for PyTorch 2.5+
    device_map="auto"
)
tokenizer = AutoTokenizer.from_pretrained("bhismaperkasa/gemma-3-1B-it-form-generator-q4_4096")
model.eval()

# Generate
prompt = "<start_of_turn>user\nbuatkan form login<end_of_turn>\n<start_of_turn>model\n"
inputs = tokenizer(prompt, return_tensors="pt").to(model.device)

outputs = model.generate(
    **inputs,
    max_new_tokens=256,
    temperature=0.7,
    top_p=0.95,
    top_k=64,
    do_sample=True
)

result = tokenizer.decode(outputs[0], skip_special_tokens=True)
print(result.split("<start_of_turn>model\n")[-1])

Android (TFLite)

Step 1: Convert to TFLite

# Install ai-edge-torch
pip install ai-edge-torch ai-edge-torch-generative

# Convert
python convert_to_tflite.py --model_path=./gemma-3-1B-it-form-generator-q4_4096

Step 2: Use in Android

// Load TFLite model
val model = Model.createModel(context, "model_int8.tflite")

// Run inference
val output = model.generate("buatkan form login")

📋 Example Output

Input:

buatkan form pendaftaran event dengan nama, email, dan nomor telepon

Output:

{
  "id": "form_event_registration",
  "title": "Form Pendaftaran Event",
  "category": "registration",
  "formDefinition": {
    "sections": [
      {
        "sectionId": "section_1",
        "title": "Informasi Peserta",
        "fields": [
          {
            "fieldId": "nama_lengkap",
            "label": "Nama Lengkap",
            "fieldType": "TEXT",
            "required": true
          },
          {
            "fieldId": "email",
            "label": "Email",
            "fieldType": "EMAIL",
            "required": true
          },
          {
            "fieldId": "nomor_telepon",
            "label": "Nomor Telepon",
            "fieldType": "PHONE",
            "required": true
          }
        ]
      }
    ]
  }
}

🔧 Technical Notes

Why BF16?

• ✅ Prevents NaN issues on PyTorch 2.5+
• ✅ Better numerical stability
• ✅ Supported by modern GPUs (Ampere+)
• ✅ No accuracy loss vs FP32

Why No Quantization?

Model trained without 4-bit/8-bit quantization because:

1. Better TFLite conversion compatibility
2. No quantization artifacts
3. Cleaner merge (no corruption)
4. TFLite will quantize to INT8 anyway

Model Size

• PyTorch (BF16): ~540 MB
• TFLite (FP32): ~250 MB
• TFLite (FP16): ~130 MB
• TFLite (INT8): ~70 MB ⭐ Recommended

🎓 Training Details

• Framework: Unsloth (2x faster training)
• Precision: BF16 pure (no quantization)
• LoRA Rank: 128
• Batch Size: 8
• Learning Rate: 5e-5
• Epochs: 4
• Final Loss: ~0.23-0.25
• Accuracy: ~93-95%
