# SLM Packager

**A Unified Runtime & Developer Layer for Small Language Models**

SLM Packager is an open-source toolkit for running, packaging, and evaluating Small Language Models (1B-7B parameters) across different formats and runtimes. Think of it as **Terraform for SLMs** — making model deployment simple, reproducible, and developer-friendly.

## ✨ Features

- 🎯 **Model Registry**: One-command downloads from HuggingFace with `slm pull`
- 🔄 **Multi-Runtime Support**: llama.cpp (GGUF), Transformers (PyTorch), ONNX
- ⚡ **GPU Acceleration**: MPS (Apple Silicon), CUDA (NVIDIA), Metal (llama.cpp)
- ⚙️ **Auto-Quantization**: On-device model quantization with automatic tool setup

## 🚀 Quick Start

### Installation

```bash
git clone https://github.com/Ayo-Cyber/slm-packager.git
cd slm-packager
pip install -e .
```

### Pull & Run a Model

```bash
# List available models
slm list

# Pull GPT-2 (500MB, fast for testing)
slm pull gpt2

# Run it
slm run gpt2 --prompt "Explain AI in one sentence"
```

That's it! The model downloads, auto-configures, and runs.

### Pull a GGUF Model

```bash
# Pull TinyLlama with llama.cpp (637MB)
slm pull tinyllama

# Run with different parameters
slm run tinyllama --prompt "Write a haiku"
```

## 📦 Available Models

| Model | Size | Runtime | Description |
|-------|------|---------|-------------|
| **gpt2** | 500MB | transformers | OpenAI GPT-2, fast to download |
| **tinyllama** | 637MB | llama.cpp | 1.1B chat model, CPU-optimized |
| **phi-2** | 1.6GB | llama.cpp | Microsoft's 2.7B reasoning model |
| **qwen-1.8b** | 1.1GB | llama.cpp | Alibaba's efficient chat model |

View all: `slm list`  
Pull with specific quantization: `slm pull tinyllama --quant q8_0`

## 🛠️ CLI Commands

```bash
# Model management
slm list                    # Show available models
slm list --installed        # Show downloaded models
slm pull <model>            # Download a model
slm pull <model> --list-variants  # Show quantization options

# Running models
slm run <model> --prompt "Your prompt"
slm run <config.yaml> --prompt "Your prompt"

# Quantization (auto-downloads tool)
slm quantize input.gguf output.gguf --type q4_k_m

# Benchmarking
slm benchmark <model>

# API server
slm serve --port 8000

# Manual config creation
slm init
```

## ⚡ GPU Acceleration

SLM Packager supports GPU acceleration across different hardware platforms.

### Apple Silicon (MPS) - Zero Setup Required! 🍎

**No installation needed** - works out of the box on M1/M2/M3 Macs!

```bash
# Create GPU-accelerated config
slm init --name gpt2 --path gpt2 --format transformers --runtime transformers --device mps -o gpt2-gpu.yaml

# Run on GPU
slm run gpt2-gpu.yaml --prompt "Explain quantum computing"
```

**Real Performance (M2 Pro):**
```
GPT-2 Performance Comparison
├─ CPU:  1.3 tokens/sec
└─ MPS:  2.4 tokens/sec  ⚡ 2.14x faster!

Tested on: M2 Pro, macOS 14.x, GPT-2 (124M parameters)
```

**Requirements:**
- macOS 12.3 or later
- Apple Silicon (M1/M2/M3 series)
- PyTorch 1.12+ (included with installation)

### NVIDIA GPU (CUDA)

```bash
# Install llama.cpp with CUDA support
CMAKE_ARGS="-DLLAMA_CUBLAS=on" pip install llama-cpp-python --no-cache-dir

# Set gpu_layers in config
runtime:
  type: llama_cpp
  device: cuda
  gpu_layers: 32  # Offload layers to GPU
```

**Expected Performance:**
- 2-5x speedup vs CPU
- Depends on GPU, model size, and layers offloaded

### llama.cpp Metal (Apple Silicon)

For GGUF models with llama.cpp on Apple Silicon:

```bash
# Rebuild with Metal support
CMAKE_ARGS="-DLLAMA_METAL=on" pip install llama-cpp-python --no-cache-dir

# Use GPU layers in config
runtime:
  type: llama_cpp
  device: cpu  # Metal auto-detected
  gpu_layers: 32  # Offload to GPU
```

## 📖 Runtime Comparison

Choose the right runtime for your use case:

| Runtime | Best For | Pros | Cons |
|---------|----------|------|------|
| **llama.cpp** | Production, efficiency | Fast, low memory, quantized | GGUF format only |
| **transformers** | Development, flexibility | Latest models, GPU support | Higher memory |
| **ONNX** | Cross-platform, optimization | Fast, portable, optimized | Requires model export |

### When to Use Each

**llama.cpp (GGUF):**
- ✅ Production deployments
- ✅ Limited memory/CPU
- ✅ Want quantization
- ✅ Edge devices

**transformers (PyTorch):**
- ✅ Development & experimentation  
- ✅ Latest HuggingFace models
- ✅ Fine-tuning workflows
- ✅ GPU available

**ONNX:**

## 🎯 Example Workflows

### Developer: Fine-Tune & Quantize

```bash
# 1. Fine-tune your model (external tool)
# 2. Quantize it
slm quantize my-model.gguf my-model-q4.gguf --type q4_k_m

# 3. Test it
slm run my-model-q4.gguf --prompt "Test prompt"

# 4. Benchmark it
slm benchmark my-model-q4.gguf
```

### Researcher: Compare Runtimes

```bash
# Pull same model, different runtimes
slm pull gpt2              # Transformers
slm pull tinyllama         # llama.cpp

# Benchmark both
slm benchmark gpt2
slm benchmark tinyllama

# Compare results
```

### MacBook User: GPU-Accelerated Inference

```bash
# Zero setup - just run!
slm pull gpt2
slm init --name gpt2 --path gpt2 --device mps -o gpt2-gpu.yaml
slm run gpt2-gpu.yaml --prompt "Hello!"

# 2.14x faster than CPU! ⚡
```

### ONNX User: Export & Run

```bash
# 1. Export model to ONNX
pip install "optimum[exporters]"
optimum-cli export onnx --model gpt2 --task text-generation-with-past models/gpt2-onnx/

# 2. Create config  
slm init --name gpt2 --path models/gpt2-onnx --format onnx --runtime onnx -o gpt2-onnx.yaml

# 3. Run (13.8 tok/s on CPU!)
slm run gpt2-onnx.yaml --prompt "Hello world"
```
