Record completeness
Claims
Mercury Coder Mini and Small achieve state-of-the-art throughputs of 1109 tokens/sec and 737 tokens/sec on NVIDIA H100 GPUs and outperform speed-optimized frontier models by up to 10x on average while maintaining comparable quality.
The assumption that independent evaluations by Artificial Analysis and Copilot Arena rankings accurately measure both speed and quality in a way that generalizes beyond the tested benchmarks and real-world developer use.
Mercury Coder diffusion LLMs achieve throughputs of 1109 and 737 tokens per second on H100 GPUs, up to 10x faster than frontier models with comparable quality.
