Mercury 2
Mercury 2 is the world's fastest reasoning LLM, built on Inception Labs' diffusion architecture. It generates tokens in parallel rather than sequentially, achieving over 1,000 tokens/sec on NVIDIA Blackwell GPUs — making reasoning-grade quality viable within real-time latency budgets for agents, voice, and search pipelines.
