## 🌟 概述

🚀 **SenseNova U1** 是全新一代原生多模态模型系列，在单一架构中统一了多模态理解、推理与生成。
它代表着多模态 AI 的根本性范式转变：**从模态集成走向真正的统一**。SenseNova U1 不再依赖适配器在不同模态之间进行翻译，而是以原生方式跨语言与视觉进行思考与行动。

视觉理解与生成的统一开启了巨大的可能性。SenseNova U1 立足于**数据驱动学习阶段**（如 ChatGPT），并指向下一阶段——**智能体学习阶段**（如 OpenClaw），以原生多模态的方式进行学习、思考和行动。

#### 🏗️ *核心支柱：*

SenseNova U1 的核心是 **[NEO-unify](https://huggingface.co/blog/sensenova/neo-unify)** —— 一个为多模态 AI 而设计、从第一性原理出发的全新架构：*它彻底摒弃了视觉编码器（VE）与变分自编码器（VAE），因为像素与文字信息在本质上是深度相关的。* 其主要特性如下：

- 🔗 端到端地将语言与视觉信息建模为统一整体。
- 🖼️ 在保留语义丰富度的同时，维持像素级的视觉保真度。
- 🧠 通过原生 MoT 实现跨模态推理，效率高、冲突少。

#### ✨ *能力突破：*

基于这一全新的核心架构，SenseNova U1 在多模态学习中展现出卓越的效率：

- 🏆 **理解与生成均达到开源 SoTA**：SenseNova U1 在统一多模态理解与生成上树立了新的标杆，在多种理解、推理与生成基准上均达到开源模型中最先进的水平，比肩商用大模型。

- 📖 **原生图文交错生成**：SenseNova U1 可以用单一模型在单次生成流程中连贯产出图文交错内容，支持生活指南、旅行日记等既需要清晰表达又富有叙事性与表现力的场景，把复杂信息浓缩为直观的图示。

- 📰 **高密度信息呈现**：SenseNova U1 在高密度视觉信息表达上展现出强大能力，能够生成结构丰富、排版复杂的内容，适用于知识图解、海报、PPT、漫画、简历等多种信息密集型场景。

#### 🌍 *不止于多模态：*

- 🤖 视觉-语言-动作（VLA）
- 🌐 世界建模（WM）

The action involves the male peacock trying to attract a female. 2. <b>Reasoning Process:</b> Male peacocks perform this ritual by fanning their tail feathers into a massive, colorful circular display. 3. <b>Establish the frame:</b> The frame captures the male peacock in a full-body shot to show the entire display. The angle is eye-level to emphasize the height of the tail feathers. 4. <b>Set the lighting and color:</b> Natural lighting illuminates the colorful circular display with soft shadows. The palette features vibrant blues and greens on the tail feathers. 5. <b>Lock the style:</b> The style is a realistic photograph with sharp focus on the male peacock. The finish is natural without artistic filters. 6. <b>Explicit Prompt:</b> A vibrant male peacock with his tail feathers fully fanned out in a wide, iridescent display of blues and greens, standing in a garden.</div></td>

The wood is floating on the surface while the iron block is submerged at the bottom. 2. <b>Reasoning Process:</b> The wood is less dense than water so it will float, while the iron is denser and will sink to the bottom. 3. <b>Establish the frame:</b> The composition is a vertical medium shot centering the rectangular tank within the frame. The camera angle is eye-level to clearly display the water line and the submerged base. Focus is sharp across the entire depth of the tank to ensure both materials are distinct. 4. <b>Build the environment:</b> The scene is contained entirely within the clear glass walls of the water tank. The water fills the majority of the volume, providing a medium for the floating wood and sunken iron block. The background remains out of focus to keep attention on the tank's interior. 5. <b>Set the lighting and color:</b> Soft natural light illuminates the scene from the left, creating gentle reflections on the water surface. The color palette features the brown grain of the wood contrasting against the dark grey metallic finish of the iron. Shadows are soft and diffused through the liquid. 6. <b>Explicit Prompt:</b> A realistic photo of a transparent water tank showing a piece of wood floating on the surface and an iron block resting at the bottom.</div></td>

The context specifies Naples, Italy, as the country of origin for this food item. 2. <b>Reasoning Process:</b> Naples is in Italy, and a classic dish is a Neapolitan pizza. 3. <b>Establish the frame:</b> The Neapolitan pizza is captured in a close-up shot that fills the central frame. The angle is slightly elevated to show the round form of the dish clearly. 4. <b>Set the lighting and color:</b> Soft lighting illuminates the surface of the Neapolitan pizza to reveal texture. Warm tones dominate the color palette, emphasizing the baked nature of the dish. 5. <b>Lock the style:</b> The image utilizes a realistic photographic style with sharp focus on the main subject. The finish appears natural and appetizing, suitable for food documentation. 6. <b>Explicit Prompt:</b> A delicious Neapolitan pizza with a soft, charred crust, tomato sauce, and fresh mozzarella, served on a rustic wooden table, realistic food photography.</div></td>

The prompt specifies the reacting state of the chemical mixture. 2. <b>Reasoning Process:</b> The reaction produces carbon dioxide gas, which would be visible as a steady stream of bubbles rising through the liquid. 3. <b>Establish the frame:</b> The camera frames the solution closely to capture the details of the reaction. The composition centers on the liquid where the gas is visible. 4. <b>Set the lighting and color:</b> The liquid appears clear, allowing the white bubbles to stand out distinctly. The lighting is bright and even to illuminate the stream of gas. 5. <b>Lock the style:</b> The image maintains a realistic photographic style suitable for scientific observation. The focus is sharp on the reacting solution and bubbles. 6. <b>Explicit Prompt:</b> A test tube filled with a clear liquid and a rapid, effervescent stream of carbon dioxide bubbles rising to the surface, laboratory experiment.</div></td>

## ⚠️ 进行中的改进

尽管在各项任务上表现优异，当前版本仍有若干已知局限有待改进：

* **视觉理解**：
  当前模型支持的上下文长度最长为 **32K** tokens，在需要更长或更复杂视觉上下文的场景下可能受到限制。

* **人体生成**：
  对人体细粒度细节的处理仍有挑战，尤其是当人物在画面中占比较小，或与周围物体存在复杂交互时。

* **文字生成**：
  文字渲染有时会出现拼写错误、字符变形或格式不一致的问题，且对 prompt 的措辞较为敏感，在文字密集场景下尤为明显。(最佳实践请参见 [`提示词增强`](./docs/prompt_enhancement_CN.md))

* **图文交错生成**：

  * 作为实验性功能，图文交错生成仍在持续演进中，性能可能尚未达到专用文生图（T2I）流程的水平。

  * **Beta 状态：** 强化学习尚未针对图像编辑、推理及图文交错任务进行专项优化，当前性能与 SFT 模型相当。

我们将上述方向列为持续迭代的重点，期待在后续版本中不断改进。

### 💾 低显存推理（GGUF + VRAM 模式）

针对单张消费级显卡的部署场景，我们在 `transformers` 路径上提供两项可独立启用、也可组合使用的低显存特性。

#### GGUF 量化权重

在四个推理脚本（`t2i`、`editing`、`interleave`、`vqa`）中传入 `--gguf_checkpoint`，即可使用 `diffusers` GGUF Linear 层加载量化后的 `.gguf` 权重，替代原始 bf16 safetensors 权重。`--model_path` 仍需指定（用于加载 tokenizer / config 及非语言模型权重）。

```bash
# 一次性安装可选依赖
uv pip install -e ".[gguf]"   # 或：pip install "gguf>=0.10.0" "diffusers>=0.30.0"

python examples/t2i/inference.py \
  --model_path sensenova/SenseNova-U1-8B-MoT \
  --gguf_checkpoint /path/to/SenseNova-U1-8B-MoT-Merger-Q4_K_M.gguf \
  --prompt "A male peacock trying to attract a female" \
  --output output.png
```

`SenseNova-U1-8B-MoT-Merger` 的 GGUF 权重（提供 Q3 / Q4 / Q5 / Q6 / Q8 等多档量化）：

| 量化权重 | HF 链接 |
| :------- | :------ |
| SenseNova-U1-8B-MoT-Merger-gguf | [🤗 smthem/SenseNova-U1-8B-MoT-Merger-gguf](https://huggingface.co/smthem/SenseNova-U1-8B-MoT-Merger-gguf) |

> 🙏 特别感谢 GitHub 用户 [@smthem](https://github.com/smthem) 为社区贡献 GGUF 量化权重。

#### `--vram_mode`：单卡分层卸载

`--vram_mode` 将语言模型各层常驻 CPU pinned memory，仅在前向时按需流式拷贝到 GPU 上参与计算，从而显著降低权重的 VRAM 占用，激活值仍保留在显卡上。

| 模式 | 行为 | 适用场景 |
| :--- | :--- | :--- |
| `full`（默认） | 不做卸载，整模放在 GPU 上 | 显存充裕，追求最快速度 |
| `low` | 同步逐层 CPU↔GPU 交换 | 显存最为紧张 |
| `balanced` | 异步预取，将 H2D 拷贝与计算重叠 | 显存吃紧但希望恢复部分速度 |

```bash
python examples/t2i/inference.py \
  --model_path sensenova/SenseNova-U1-8B-MoT \
  --vram_mode balanced \
  --prompt "..." --output output.png
```

`--gguf_checkpoint` 与 `--vram_mode` 可叠加：在 ~16 GB 消费卡上推荐使用 `Q4 GGUF + balanced` 组合。


### ⚡ 使用 LightLLM + LightX2V 运行

面向生产环境的部署，我们在 **[LightLLM](https://github.com/ModelTC/lightllm)**（理解）和 **[LightX2V](https://github.com/ModelTC/lightx2v)**（生成）之上协同设计了一套专用推理栈。两个引擎以解耦方式运行，可以各自使用独立的并行策略与资源配额，中间通过低开销传输通道连接。

在单节点 `TP2 + CFG2` 配置下，该推理栈在 H100 / H200 上为 **2048×2048** 图像提供约 **~0.15 s/step**、**~9 s 端到端**的表现；相较 Triton 基线，我们基于 FA3 的混合掩码注意力带来 ~**2.4–3.2×** 的 prefill 加速。完整的单卡性能数据见 [`docs/inference_infra_CN.md`](./docs/inference_infra_CN.md)。

我们提供了官方 Docker 镜像，一行命令即可完成部署：

```bash
docker pull lightx2v/lightllm_lightx2v:20260407
```
