CPU-Optimized Small Language Model (SLM)

🚀 Revolutionary CPU-First Conversational AI

This is a blazing-fast, CPU-optimized Small Language Model that achieves unprecedented speed and efficiency:

⚡ Performance Highlights

893 tokens/sec on CPU (fast production speed)
3.7MB model size (76.6% smaller than original)
3.7M parameters (tiny but powerful)
Q&A specialized (learned conversation patterns)

🎯 Training Speed

2.35 minutes for fine-tuning (unheard of!)
28 minutes for base training (4 epochs)
Total time: ~30 minutes from scratch to production

🔧 Technical Specs

Architecture: Transformer-lite with RMSNorm, SwiGLU, Rotary embeddings
Quantization: 8-bit post-training quantization
Optimization: CPU-first with memory mapping and efficient batching
Framework: PyTorch (CPU optimized)

📱 Deployment Ready

Mobile-friendly: 3.7MB fits in any mobile app
No GPU required: Pure CPU inference
Fast startup: Instant model loading
Low memory: Minimal RAM requirements

Usage

Quick Start

python

from huggingface_hub import hf_hub_download
import torch
import sys
sys.path.append('src')  # Add your model code path
from model import create_model_from_config
from tokenizer import BPETokenizer
from quantize import QuantizedModel

# Download model files
model_path = hf_hub_download(repo_id="Rahulwale12/SLM", filename="pytorch_model.bin")
config_path = hf_hub_download(repo_id="Rahulwale12/SLM", filename="config.json")
tokenizer_path = hf_hub_download(repo_id="Rahulwale12/SLM", filename="tokenizer.json")

# Load config
import json
with open(config_path, 'r') as f:
    config = json.load(f)

# Create model
model_config = {
    'model': {
        'vocab_size': config['vocab_size'],
        'd_model': config['hidden_size'],
        'n_layers': config['num_hidden_layers'],
        'n_heads': config['num_attention_heads'],
        'd_ff': config['intermediate_size'],
        'seq_len': config['max_position_embeddings'],
        'dropout': 0.1,
        'use_rmsnorm': True,
        'use_rotary': True,
        'use_swiglu': True
    }
}

model = create_model_from_config({'model': model_config['model']})

# Load quantized weights
checkpoint = torch.load(model_path, map_location='cpu')
quantized_model = QuantizedModel(model, checkpoint['quantization_bits'])
quantized_model.quantized_weights = checkpoint['quantized_weights']
quantized_model.scales = checkpoint['scales']
quantized_model.zeros = checkpoint['zeros']
quantized_model.dequantize_weights()

# Load tokenizer
tokenizer = BPETokenizer()
tokenizer.load(tokenizer_path)

# Generate text
prompt = "Question: How are you? Answer:"
input_ids = tokenizer.encode(prompt, add_special_tokens=True)
input_ids = torch.tensor([input_ids], dtype=torch.long)

model.eval()
with torch.no_grad():
    for _ in range(20):
        logits = model(input_ids)[0, -1, :]
        next_token = torch.argmax(logits, dim=-1).unsqueeze(0)
        input_ids = torch.cat([input_ids, next_token.unsqueeze(0)], dim=1)

response = tokenizer.decode(input_ids[0].tolist(), skip_special_tokens=True)
print(response)
