This drone flies itself for 10 cents. pip install typesafe-sdk Camera only, no scripted path, no waypoints. A judgment model sits in the loop at 2.5 Hz. Jev does not generate text. It returns typed decisions with probabilities. Here is what it actually does: → reads a JSON scene built from depth and segmentation → answers three questions per call: go over, go around, or brake → every answer carries a probability, not a sentence → code keeps the veto at 50 Hz and overrides it near obstacles → 80 calls, 65 seconds of flight, 0.11 s median latency Built on the Skydio X2 airframe from MuJoCo Menagerie, flown by a geometric controller. And here is the part that got me: With the model disabled the same stack stops dead at station 2, every run. It cannot express "fly over it". With Jev it clears all 77.5 m. 49 stars. MIT.
