Running a 28.9M parameter LLM on an $8 microcontroller

>esp32-s3

This microcontroller is a beast, currently using it to do dev work on a pi4.

Having two usb ports with one otg lets you do some neat things that would cost $100+ otherwise

This is a really neat use of the per-layer embedding trick. It's also worth noting that there viable TTS models that are ~20-30M param, so it might mean you can have a ESP32 with no network access read stuff out to you in near real time!

Why can't this scale to run much larger models on CPU backed by flash with good access patterns?

Super cool, thank you for sharing!

This is a really cool project. Thanks for sharing!

9.7 tokens/sec actually seems like a lot! That’s fun!
