## In-depth Testing of Local Large Model Inference on Apple M4: Performance Analysis of MLX + DDTree Speculative Decoding vs. Ollama

This evaluation focuses on the local large language model inference performance of the Apple M4 chip, comparing the performance differences between the MLX framework and Ollama, and analyzing the acceleration effect of DDTree speculative decoding technology. Key findings include that the MLX framework is significantly superior to Ollama, the MoE architecture shows great performance advantages on Apple Silicon, and DDTree technology further improves inference speed.

## Background: The Rise of Edge AI Inference

With the development of large language model technology, efficiently running models on local devices has become a focus of attention. Apple Silicon has become an ideal platform for edge AI inference due to its unified memory architecture and neural engine, but choosing the right framework and optimization strategy is crucial for performance.

## Testing Environment and Methods

The test is based on MacBook Air M4 (10 cores: 4 performance cores + 6 efficiency cores, 32GB unified memory) with macOS 15.7 Sequoia operating system. The task is to generate a Python implementation code of a red-black tree with up to 200 tokens. Measurement method: 2 warm-up runs + 5 formal timing runs, taking the median value; the metric is pure generation speed (tok/s) excluding pre-filling time.

## Key Findings: Significant Advantages of MLX

### Qwen3.6-35B-MoE Model Comparison
- DDTree (MLX): 28.7 tok/s, 2.33x faster than Ollama
- Plain MLX: 26.9 tok/s, 2.19x faster than Oll
- Ollama (GGUF-Q4_K_P): 12.3 tok/s (baseline)
