Build high-performance AI apps with Mercury
Inception’s diffusion LLMs (dLLMs) deliver frontier LLM quality at 5x greater speed.
Overview
(Un)paralled speeds
Our models run at 1000+ tokens per second on commercial NVIDIA GPUs, enabling instant, in-the-flow AI solutions.
Exceptional Quality
We match the intelligence of speed-optimized autoregressive models like GPT-5 mini and Claude Haiku 4.5.
Seamless integration
Our models are OpenAI compatible and a drop-in replacement for traditional LLMs.
