Mercury 3: Diffusion at scale

Inception released Mercury 3, a diffusion-based large language model. The company says it beats GPT-6 Luna and Claude Haiku 5.5 on several benchmarks and runs 4–8x faster.

Why it matters: Mercury 3 scales past 40x the parameters of Mercury 1 while keeping similar speed, giving a like-for-like read on text diffusion at larger size.
