Redis Creator antirez Open-Sources MiniMax H3 Mac Inference Engine

Renowned developer and Redis founder antirez has open-sourced h3.c, a local inference engine for the MiniMax-H3 model tailored specifically for Apple Silicon (Metal architecture). The tool enables Mac users to run the model directly on-device, and MiniMax officially tweeted its appreciation for his contribution.

Confirmed

• Project Core: Leveraging Apple's Metal API, h3.c achieves native GPU-accelerated inference for MiniMax-H3 on Mac computers, boosting the performance of on-device AI workloads.
• Supported Features: The engine is designed to run multimodal models locally, enabling generative tasks like text-to-video and text-to-image, and can be integrated with tools like drawthingsapp.
• Testing: antirez conducted performance tests on a 5-second Ref2VA fragment using an M5 Max 128GB machine and integrated the relevant components.

Why It Matters

This move further validates the appeal of the open-source community model. Without formal employment, top developers can spontaneously adapt models to various hardware environments, significantly lowering the barrier for Mac users to experience cutting-edge multimodal large models.
