In mid‑October 2026 the team launched **d1‑ultra**, a full‑stack redesign of our decision‑model architecture.

After d1, we didn't want to chase incremental improvements.

We went back to the drawing board and redesigned it from scratch: data, model, evals, serving, all backed by ablations.

The result is d1-ultra, the world's best decision model! 🥳

d1‑ultra is multimodal and supports 44 languages.

It ranked #1 on the @ArtificialAnlys Decision Index (65) and leads all eight categories of the 112‑evaluation suite.
