Ollama Achieves 1.6x Speed Boost on Macs by Integrating Apple's MLX Framework
Key Takeaways
- ▸Ollama 0.19 achieves 1.6x faster prompt processing and 2x faster response generation on Macs using Apple's MLX framework
- ▸M-series Macs with GPU Neural Accelerators see the largest performance improvements, particularly newer M5-series chips
- ▸Enhanced memory management makes AI coding tools and chat assistants more responsive during extended use sessions
Summary
Ollama, the popular local AI model runner, has released an update that leverages Apple's MLX machine learning framework to significantly accelerate performance on Mac computers. The new version, Ollama 0.19 (preview), delivers a 1.6x speed improvement in prompt processing and nearly double the speed in response generation, with the largest gains visible on Macs equipped with M-series chips and Apple's new GPU Neural Accelerators.
Beyond raw speed improvements, the update introduces smarter memory management that enhances responsiveness during extended use of AI-powered applications. The optimization is particularly beneficial for users running personal assistants and coding agents on their Macs. Currently, the preview release requires a Mac with over 32GB of unified memory and initially supports Alibaba's Qwen3.5 model, with plans to expand model compatibility in future releases.
