Overview
Companion bot built into a suitcase around a Jetson Orin NX Super 16GB, running Gemma 4 E4B with about 200ms cached time-to-first-token and 30+ sensors fed into every prompt. It has no WiFi, Bluetooth or cellular at all, and Tom's Hardware covered it.
How it works
llama.cpp Gemma 4 E4B + SenseVoice STT + Piper TTS with mouth sync and a PixiJS face; sensor data goes at the end of the prompt to keep the cache stable.
Hardware
- Jetson Orin NX Super 16GB
