Can you actually run a generative AI model on a $5 microcontroller?

In this video, I build, train, optimize, and run a tiny AI model directly on an ESP32-S3 camera device. No GPU. No powerful computer doing the inference in the background. The model runs on the microcontroller itself.

We look at how the model is reduced using downsampling and INT8 quantization, how TinyML works within extremely limited memory, and what happens when we compare 32x32, 64x64, and 128x128 models.

I’ll also show you the browser-based interface I built for training models, testing them on your computer, creating firmware, selecting different visual styles, and uploading everything directly to the ESP32-S3 over USB-C.

This is not Midjourney running on a microcontroller. It is an experiment in how far we can shrink an AI model and still get useful visual processing from extremely inexpensive hardware.

If you build something with this project, modify the code, or create your own tiny AI model, let me know in the comments. And if the project is useful, consider giving the GitHub repository a star.
