Lossy — Training Pets

You kick off a training run. An egg appears on your lock screen. While your model learns, the egg wobbles, glows, and cracks — happy when loss is falling, nervous when it spikes, sleepy when things plateau. When the run finishes, it hatches, and you meet what you made: a one-of-a-kind pixel creature whose personality comes from how the training actually went. If the run crashes, well… you'll want to be more careful with the next egg. Lossy is a training monitor with a heartbeat. Under the cute is a real tool: - Loss curve and progress at a glance, on OLED black - Live Activities: hatch progress on your lock screen and Dynamic Island - Widgets: your incubator on the home screen - Real-time push when a run finishes or crashes — no more tab-refreshing - A shelf of every creature you've ever hatched, each one a training run you can look up Setup is two lines: pip install lossy import lossy run = lossy.init(project="my-project") lossy.log({"train/loss": loss}, step=step) Pair once with a token from the app. No account, no API keys, no analytics — and Unpair erases everything server-side. Your metrics belong to you; we just make them adorable.
