M4 max for Llama 3 large model

how to effectively use MacBook Pro with M3 Max /M4 Max for running Llama 3 large models:

Model Size and Memory Requirements

70B Model Limitations

  • The 70B model requires approximately 140GB RAM for unquantized operation

  • Cannot run full 70B model unquantized on 128GB MacBook Pro

  • Needs a 192GB M2 Ultra Mac Pro or Studio for unquantized operation

Performance Metrics

Quantized Performance

  • 4-bit OmniQuant version (gs=128) achieves ~8.42 tokens/sec

  • Q6_K quantized version runs at 4.5-5.5 tokens per second

  • Q8_0 quantization maintains similar performance at 4.7 tokens per second

Optimization Tips

  • Use quantized versions for better memory efficiency

  • Take advantage of Metal Performance Shaders (MPS) for M-series chips

  • Consider using the 8B model for better performance if full 70B model isn't necessary

Model Options

Available Versions

  • Llama 3 8B: More efficient for local deployment

  • Llama 3 70B: Requires quantization for 128GB systems

  • New tokenizer with 128K vocabulary for improved efficiency

For optimal performance on MacBook Pro with 128GB RAM, it's recommended to use quantized versions of the larger models or the smaller 8B model for development and testing purposes.
