Zo
A 24/7 multilingual AI livestream-shopping seller, run end-to-end by Gemma 4 on Cactus.
Built at the Cactus × Google DeepMind × YC Gemma 4 Voice Agents Hackathon (April 2026). Gemma 4 E4B on-device handles five jobs — product vision, pitch generation, comment classification, voice-intent parsing, and Whisper transcription — driving a three-tier library of pre-rendered MP4 clips stitched live. Only ~10% of novel responses get a Wav2Lip lip-sync overlay on a RunPod 5090. ~$144/mo per seller vs. ~$9,628/mo cloud equivalent.
