TL;DR

The OLMoE 1B-7B model runs at Grade S on the Apple M4 Max with the Q8_0 quantization, achieving ~314 tok/sec, making it an excellent choice for high-performance inference.

Prerequisites

Before starting, ensure you have at least 10GB of free disk space, macOS 12.3 or later, and Xcode Command Line Tools installed. You can install Xcode CLT by running `xcode-select --install` in your terminal.

Expected performance

With the Q8_0 quantization, you can expect the OLMoE 1B-7B model to run at approximately 314 tokens per second, using around 7.3GB of VRAM. This leaves you with about 120.7GB of VRAM headroom, allowing for a practical context window of up to 4096 tokens without significant performance degradation.

1. Install runtimeOllama (preferred on Apple Silicon)

brew install ollama
ollama init

2. Download the model

Download the Q8_0 quantized version of OLMoE 1B-7B, which is a 6.9GB file.

ollama pull bartowski/OLMoE-1B-7B-0924-Instruct-GGUF:OLMoE-1B-7B-0924-Instruct-Q8_0.gguf

3. Run it

ollama run OLMoE-1B-7B-0924-Instruct-Q8_0 --interactive
ollama chat --model OLMoE-1B-7B-0924-Instruct-Q8_0

4. Optimize for M4 Max

For optimal performance on the Apple M4 Max, leverage the Metal/MLX backend to utilize the 128GB of unified memory efficiently. Ensure that MPS layers are enabled to take full advantage of the GPU's capabilities. With 128GB of VRAM, you have ample headroom for large context windows and multiple instances.

Troubleshooting

Low inference speed or high CPU usage

Ensure that the Metal/MLX backend is properly configured by running `export OLLAMA_BACKEND=metal` in your terminal.

Out-of-memory errors during inference

Reduce the batch size or context length to fit within the available VRAM. For example, try setting a smaller context length with `ollama run OLMoE-1B-7B-0924-Instruct-Q8_0 --context-length 2048`.

Model not found or download issues

Verify that the model was correctly pulled by checking the Ollama cache directory with `ollama list`. If the model is missing, try pulling it again with `ollama pull bartowski/OLMoE-1B-7B-0924-Instruct-GGUF:OLMoE-1B-7B-0924-Instruct-Q8_0.gguf`.

Alternative runtimes

While Ollama is the preferred runtime for Apple Silicon, you can also consider LM Studio for a more graphical interface, llama.cpp for fine-grained control over quantization, or the MLX runtime for direct Metal integration. Use these alternatives if you need specific features or optimizations not available in Ollama.
