vLLM语义路由器团队拥有发布 d3-ultra，是Apache-2.0下的一种27B多式决定模型。 d3-超决定模型不生成文本。 它读出一次输入，并返回每个问题的每个答案的概率。 对开发者来说，这意味着从1个开口量的呼叫中进行路由，分类，视觉地平线和视频检查。
TL; DR 数据
- 大小：26.09B参数(强度，包括一个0.46B视觉编码器)；每个问题131,072个上下文符号。
- 运行在：1 AMD Instinct MI325X上测试，重量为BF16；尚未列出正式的量化变体。
- 表现：在球队自己的私人测试中，6个决定模型的最高SR-Text得分。
- 最佳：97.8，关于SR-Text工具和自动化(chance校正准确性)。
- 最糟的是：SR-Box上54.6%(9个域)，低于其兄弟d3-涡轮的5.0分。
D3 -UTRA是什么东西？
d3-ultra是一个来自vLLM语义路由器的System One决定模型，以概率解答打出的问题。 这是第3.0号决定的最新成员，这个家庭从0.6B到27B不等。
您发送一个状态( 文本或 JSON，加上图像或视频) 和一组问题。 每个问题都有一个类型：
- 选择：从几个选项中选择一个。
- 是/否：还原为是的概率。
- 分数：比例。
找到影像或视频瞬间的东西
- 追踪整个视频的目标
图像也可以坐在问题和选项内部。 一个测验可以显示相片，然后提供4个蚀刻作为答案。
d3 -ltra是怎样工作的？
核心思想是国家一度。 模型读出每个请求的输入，并回答该单项的每个问题。
配置显示 Qwen3.5-建筑主干线有64层。 48为线性意向层，16为全性意向层。 该卡没有标明其基地检查站的名称。 VLLM的配方称该兄弟d3是从Qwen3.8-27B训练出来的。
盒子回答总是满怀信心地返回一个盒子。 接近0的自信意味着目标不在画面中。 超过 131,072 个符号的问题以 max 长度超过失败；任何问题都不能默默地截断。
d3-ltra在基准测试上的表现如何？.
研究团队将d3-ultra与GLIDE V1.2,d1-ultra,d3-turbo,d3和Jev 1.14进行了两次内部测试。
SR-Text有10,411个文本请求，有73,495个问题。 多数用新物品从34个公共基准测试再造出技能。 另外4,896个问题来自43个新任务家庭，如SQL检查和出票路线。 得分是偶然的：0是偶然的，100是完美的。
- d3-高射炮：87.2
- GLiDE V1.2: 85.1
- d1-ltra:83.4级
- d3-涡轮：83.1
- d3: 81.4
- 列夫1.14:73.1
d3-再引领除艺术和人类口味外的每一个领域。 在那里，d1-ltra在误差幅度内得分90.8比89.6.
SR-Box有5,678个盒子问题，涉及10个领域的4,984个图像。 在IoU 0.5或更高时，一个框算得正确。 d3-超音速得分58.2%分超过10个域，54.6%分超过9.d3-turbo得分60.0%分和59.6%分。 Jev 1.14得分45.7%分和46.9%分。 团队称 d3-turbo在自然影像上保持较强，而d3-ultra则在图表上领先。
latency：用AutoModel在1AMD Instinct MI325X上，1个关于一张照片的问题需要304ms. 255个问题需要2.16 s，每个额外问题约7.3 ms.
如何部署d3 -ltra?
有4条路线：
- 变形器：从 prered ("vllm-sr/d3-ultra"，信任 remote code=True)起为自动模具。 可选的闪光线-注意包新增快取GPU内核。
- vLLM语义路由器引擎：vllm-sr service-e vllm-sr/d3-ultra，于2026年10月25日加入PR#5449.
- 免费API：由称决定.vllm-sr.ai服务于d3-ultra，带有自由键。
-德莫：官方Hugging Face空间。

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_exceeded; nothing is silently truncated.
How does d3-ultra perform on benchmarks?
The research team compares d3-ultra with GLiDE V1.2, d1-ultra, d3-turbo, d3 and Jev 1.14 on 2 in-house tests.
SR-Text has 10,411 text requests with 73,495 questions. Most recreate skills from 34 public benchmarks with new items. Another 4,896 questions come from 43 new task families, like SQL checks and ticket routing. Scores are chance-corrected: 0 is chance, 100 is perfect.
- d3-ultra: 87.2
- GLiDE V1.2: 85.1
- d1-ultra: 83.4
- d3-turbo: 83.1
- d3: 81.4
- Jev 1.14: 73.1
d3-ultra leads every area except arts and human taste. There, d1-ultra scores 90.8 against 89.6, within the margin of error.
SR-Box has 5,678 Box questions on 4,984 images across 10 domains. A box counts as correct at IoU 0.5 or higher. d3-ultra scores 58.2% over 10 domains and 54.6% over 9. d3-turbo scores 60.0% and 59.6%. Jev 1.14 scores 45.7% and 46.9%. The team says d3-turbo stays stronger on natural images, while d3-ultra leads on charts.
Latency: on 1 AMD Instinct MI325X with AutoModel, 1 question about a photo takes 304 ms. 255 questions take 2.16 s, about 7.3 ms per extra question.
How do you deploy d3-ultra?
There are 4 routes:
- Transformers: AutoModel.from_pretrained("vllm-sr/d3-ultra", trust_remote_code=True) with transformers==5.17.0. The optional flash-linear-attention package adds fast GPU kernels.
- vLLM Semantic Router Engine: vllm-sr serve -e vllm-sr/d3-ultra, added in PR #5449 on October 25, 2026.
- Free API: the card says decision.vllm-sr.ai serves d3-ultra, with a free key.
- Demo: the official Hugging Face Space.
