Mercury is the first diffusion large language model (dLLM). Applying a breakthrough discrete diffusion approach, the model runs 5-10x faster than even speed optimized models like Claude 3.5 Haiku and GPT-4o Mini while matching their performance. Mercury's speed means that users can stay in the flow, enjoying rapid chat-based iteration and responsive completion suggestions. On Copilot Arena, Mercury ranks 1st in speed and ties for 2nd in quality.
