Ramon Chamet (Cactus): On-Device & Hybrid AI

Cactus founder Ramon Chamet explains the YC-backed startup's low-latency inference engine that runs AI models locally on phones, laptops and wearables, enabling private, offline AI. He describes the YC application process, predicts voice and ambient "always-on" assistants will define the next application layer, and discusses privacy norms around wearables like Meta Ray-Bans and Bee. He lays out Cactus's hybrid AI thesis — cloud and local models working in tandem — including a 1,500-person hackathon with DeepMind.
