h3metal engine boosts Apple Silicon image generation speed

By PulseAugur Editorial · [1 sources] ·

An open-source image generation engine called h3metal has been developed for Apple Silicon, specifically targeting M5 and M6 chips. This engine utilizes the dedicated matrix units on these processors to achieve significantly faster image generation speeds compared to existing tools like Draw Things. Benchmarks show h3metal generating images with models like FLUX.2 [klein] 4B and Z-Image-Turbo++ up to 2.3 times faster on a Mac mini, with individual denoising steps completing in under two seconds. AI

IMPACT This development could lead to faster local AI image generation on compatible Apple devices.

RANK_REASON Development of a new open-source engine for image generation on specific hardware.
