Celeris is an AI research lab building the world's fastest language models. Instead of conventional autoregressive generation, its models use a diffusion-based inference architecture that refines many output tokens in parallel, aiming to deliver near-frontier intelligence at millisecond latency for real-time voice, interactive coding, search, autonomous agents and robotics. Celeris was founded by Tom Hamer (CEO) and Jesse Clark (CTO), who previously co-founded AI search company Marqo, and came out of stealth in July 2026 with Celeris-1.
