The vLLM Semantic Router team has released d3-ultra, a 27B multimodal decision model under Apache-2.0. The d3-ultra decision model does not generate text. It reads an input once and returns a probability for every answer to every question. For developers, that means routing, classification, visual grounding and video checks from 1 open-weight call. TL;DR Size: 26.09B parameters (dense, including a 0.46B vision encoder); 131,072 tokens of context per question. Runs on: tested on 1 AMD Instinct MI325X with BF16 weights; no official quantized variant is listed yet. Performance: highest SR-Text score of the 6 decision models in the team’s own private test. Best: 97.8 on SR-Text tools and automation (chance-corrected accuracy). Worst: 54.6% on SR-Box (9 domains), 5.0 points below its sibling d3-turbo. What is d3-ultra? d3-ultra is a System One decision model from vLLM Semantic Router that answers typed questions with probabilities. It is the newest member of Decision 3.0, a family that spans 0.6B to 27B. You send a state (text or JSON, plus images or videos) and a set of questions. Each question has a type: Choice: pick 1 of several options. Yes / No: return the probability of yes. Score: rate on a scale. Box: locate something in an image or a video moment. Track: follow a target across a whole video. Images can also sit inside questions and options. A quiz can show a photo, then offer 4 etchings as answers. How does d3-ultra work? The core idea is state once. The model reads the input once per request and answers every question from that single read. The config shows a Qwen3.5-architecture backbone with 64 layers. 48 are linear-attention layers and 16 are full-attention layers. The card does not name its base checkpoint. vLLM’s recipe says the sibling d3 was trained from Qwen3.8-27B. Box answers always return exactly 1 box with a confidence. A confidence near 0 means the target is not in the picture. Questions over 131,072 tokens fail with max_length_
