Paddy API Farm is an AI farm manager for rice (paddy), built by NexusAG on Meta’s Muse Spark 1.3.

It runs a digital twin of two 6 × 6 paddy fields near Bengaluru, simulated hour by hour through a whole season. At 06:00 and 18:00, and whenever something changes (a new pest, a storm forecast, water running low), the farm sends Muse Spark, through the Meta Model API, everything it knows: weather and forecast, water depth, crop stage, pest sightings, what the robot arms are doing, and advice from its own random-forest models. Muse Spark replies in JSON with what to do, where, when and why: irrigate, spray, fertilise, puddle, transplant, scout, harvest or wait.

Before anything happens, every decision is checked by safety rules: no spraying before rain or in strong wind, labelled products only, harvest waiting periods, bee safety, fertiliser caps, and farm logic such as puddling before transplanting. Accepted decisions are carried out square by square by four simulated robot arms in a live 3D view. Farmers can watch, or switch on approve mode to accept or reject each decision themselves. Every call, reply and verdict is recorded, so a whole season can be replayed exactly.

Built with Python, NumPy, React and the Meta Model API.

If the box has a character limit, tell me the number and I’ll trim it to fit.

I’ve also restarted the reviewer’s check of the final video now that the usage limit has reset. I’ll tell you how many problems it finds.
