Liquid AI's d1-ultra Tops Decision Model Rankings with Multimodal, Calibrated-Probability Design

Liquid AI released d1-ultra on October 15, 2026, a multimodal decision model that ranks first on the Artificial Analysis Decision Index and claims state-of-the-art performance for real-world classification tasks.
