A small image generation model runs on a RP2350 microcontroller.
It has 2.4–4 million parameters and produces 128x128 face images in about 20 seconds.
The technique could enable AI generation in low-power devices.
What happened
A developer created a tiny image generation model, a latent flow transformer with 12 layers, that runs fully on a microcontroller. It has only 2.4–4 million parameters, making it extremely small.
Why it matters
The model generates 128x128 face images in about 20 seconds on a low-power microcontroller, demonstrating that complex AI tasks can run on minimal hardware. This could enable AI generation in devices where it was previously impossible.
What to watch
The developer will share the repository, allowing others to reproduce and experiment with the model. The use of CFG and Relu² activation improved image quality and efficiency, hinting at future optimizations for such tiny AI systems.

The developer's achievement shows that image generation, typically associated with large models, can be compressed to run on a microcontroller with only a few million parameters. The use of techniques like CFG and Relu² activation suggests that efficiency can be improved without sacrificing quality significantly. The decision to share the repository may encourage further experimentation in ultra-efficient AI, potentially leading to more applications in edge devices where power and memory are limited.
