FrostWise forecasts your last spring frost with an open-weight model and tells you what to plant, on your laptop, with no internet and no account. Put the phone down and get your hands in the soil.
Pick a place (or type your own climate), choose what you want to grow, and get the date the cold likely lets go, plus what to do about it.
Latitude, elevation, and your late-winter temperatures. A preset fills these from real climate norms, or type your own.
An open-weight tabular foundation model predicts your last-frost day-of-year in one CPU pass, with a 10–90% range. No training, no cloud.
A local open-weight Gemma 3 model turns that date into plain-language planting guidance for your exact crop.
Works with no signal. Both models run on your machine. On a hillside allotment with one bar of signal, a closed API is useless. FrostWise still answers.
Your location stays yours. Where you garden never leaves your laptop. No server, no account, nothing logged to someone else's cloud.
Costs nothing to run. Open weights, zero per-request fees. Run it a thousand times for a community garden and the bill is still $0.
Swap the brain. Point it at a bigger Gemma, or retrain TabPFN on your own weather station. You own the stack, not a vendor.
