> How to use upstratus: record examples with your phone, train a model on our GPUs, and download plain C for one of six supported microcontroller boards.

upstratus trains small machine-learning models for microcontrollers. You record labelled examples with a phone (motion or sound) or import a CSV of sensor readings, train a model on upstratus's GPUs, and download a zip of plain C source for one of six supported boards, which you then build and flash with that board's own tools. upstratus does not flash boards itself yet. agents/index.md says what an AI agent can and cannot do here.
