Model Card

Mercury is the world's first commercial diffusion large language model (dLLM) from Inception Labs that generates text 5-10x faster than traditional autoregressive LLMs by predicting multiple tokens in parallel. It's designed for latency-sensitive applications like voice agents, search interfaces, and chatbots while matching the quality of speed-optimized models like Claude 3.5 Haiku.
