Mercury 2.5 is Inception's most capable diffusion language model yet, generating at over 1,100 tokens per second by producing text in parallel instead of one token at a time. It brings a 40% intelligence improvement over Mercury 2, 260K context, tunable reasoning, parallel tool calls, and structured JSON — built for latency-sensitive search, voice, coding, and agent workloads.

Could you build this?
No Developing a novel diffusion-based language model capable of 1,100+ tokens/sec requires cutting-edge machine learning research, massive GPU clusters, and custom model architecture design.
What it would actually take: Building a diffusion language model requires a distributed training pipeline using PyTorch, Megatron-LM/DeepSpeed, and a cluster of hundreds or thousands of H100 GPUs. The hard part is formulating a continuous or discrete diffusion formulation for parallel text decoding that matches autoregressive perplexity while scaling to 260K context. This demands world-class AI researchers and multi-million-dollar compute budgets.
