“Our team’s been cooking 🧑🍳 D1-ultra is live, and the best decision model we’ve built. Beats Jev 1.14 across the board, #1 on the AA Decision Index, multimodal, 44 languages. Available now on the Liquid API.”
“#1 on the Artificial Analysis Decision Index at 65, and $0.042 per million input tokens with no output billing. Hard to find a cleaner launch combo than leading the board and being cheap enough to put a threshold on every decision in the stack.”
“Today we’re introducing d1-ultra, our strongest decision model to date 🫡 We made d1 much stronger across the board: real-world decisions, expert tasks, images, knowing when it doesn’t know. I really hope you will enjoy using it !”
“This is quickly becoming one of my favourite labs. Yesterday they also released a great 24b model opensource. Now this absolute beast of a model to come out of this lab, @PhishFort we’re seeing massive growth in our capabilities enabled by the new generation of decision models.”
“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! 🥳”
