Atome LM v2 (SuperESP): 12 On-Device AI Applications on a $5 Chip

2026-06-28 · Tilelli Lab · 6 min read

Atome LM started as one tiny ternary language model you could run on a $5 microcontroller. Atome LM v2 — codenamed SuperESP — turns that same 1.58-bit engine into a suite of on-device AI applications: instead of generating text, the chip now classifies the world around it, fully offline.

What v2 adds

Honest about what it is

This is a real, production-grade open kit — not magic. Several demo heads ship on physics-grounded synthetic data (clearly labelled), and you replace them with your own real data through the same CSV path. Voice keyword-spotting works but is modest on a 20 KB ternary model. We publish the numbers, the tests, and the honest limits rather than a marketing benchmark.

Get it

The v1 engine and weights are already public on GitHub and Hugging Face under Apache-2.0. The v2 SuperESP kit ships the applied layer on top. If you'd rather have it done, certified, or licensed for your product, see services.
