WMT26
Systems translate the WMT26 general task test set in 24 directions, mostly out of English, across several domains with added instructions. The shared task ranks systems by human contrastive ESA judgments.
The blind test set came out on June 18th, 2026 and references on July 27th, 2026. Cohere scores it with a GPT-5.6-Sol judge on a 0 to 100 scale, which differs from the shared task's human ranking.
