云端Cloud 开源权重Open weights 自托管Self-hosted APIAPI 商业Commercial partial lifecycle: active 核验Checked 2026-10-30

「平台 + 开源权重」双路线的图像厂商：平台输出所有权转让给用户，训练退出写在条款里；开源线自托管商用要逐模型看许可证。

The image vendor on the “platform + open weights” dual route: the platform assigns output ownership to users and the training opt-out is written into the terms; self-hosting the open-weights line commercially requires checking each model's license.

适合与不适合When to use it, when not to

适合既要托管平台、又要本机跑开源模型的人——两条线各得其所，但条款是两套。对训练数据合规敏感的场景可关注其授权数据口径。要开箱即用的风格质量，对照 Midjourney/FLUX 再选。

People who want both a hosted platform and local open models — both routes have their place, but the terms are two systems. Scenarios sensitive to training-data compliance can look at its licensed-data positioning.

Not a fit for out-of-the-box strongest style quality — compare Midjourney/FLUX before choosing.

备案信息以网信办《生成式人工智能服务已备案信息》公示名单为准（按批次滚动更新，本站只抄编号不解读）；「大陆可直连」是本站从大陆网络直连实测的结果，不是厂商承诺。GitHub 类站点当日实测有波动，口径写在依据里。Filing status is quoted from the CAC public registry (updated batch by batch; this site copies the number and does not interpret it). "Direct access" is this site's own reachability measurement from a mainland network, not a vendor promise. GitHub-hosted sites fluctuated on the measurement day — the note says so.

模型与开放条件Model & openness: 模型家族官方新闻页披露：Stable Image 系（平台）、Stable Audio 3.0（2026-05-20 发布、开源权重、官方称训练数据全授权）、Stable Diffusion 3.5 系（可自托管）等条目（2026-10-21 直抓 stability.ai/news 核验）。
Model family disclosed on the official news page: the Stable Image series (platform), Stable Audio 3.0 (released 2026-05-20, open weights, officially claimed fully licensed training data), the Stable Diffusion 3.5 series (self-hostable) and other entries (stability.ai/news direct-fetched and verified 2026-10-21).
运行位置Where it runs: 平台线：网页应用与 API，生成在云端；开源线：权重可下载、本机或自有云自托管—— 两条线是同一厂商的两种运行形态，档案主轴是平台。
Platform line: web app and API, generation in the cloud; open line: weights downloadable, self-hosted on your machine or your own cloud — the two lines are two runtime forms of the same vendor; this dossier's main axis is the platform.
本地文件Local files: 平台可上传图像作输入；开源线本机跑模型时数据不出本机（自托管形态的固有属性）。
The platform can upload images as input; on the open line, when the model runs locally the data never leaves your machine (an inherent property of the self-hosted form).
关机后的任务Tasks after shutdown: 平台生成为请求-产出制：任务在云端跑完即取；没有「关机续跑」形态的官方声明。开源线自托管时任务完全由自己的机器承载，关机续跑取决于自己的部署方式。
Platform generation is request-output based: tasks run in the cloud and are retrieved on completion; no official statement of a "keep-running-after-shutdown" form. On the open line, self-hosted tasks are carried entirely by your own machines — keep-running-after-shutdown depends on your own deployment.
工具与扩展Tools & extensions: 平台含 Brand Studio（2026-04-08 条目：品牌向创作生产平台）；企业集成线（Amazon Bedrock 2025-09-18 条目、NVIDIA NIM 2025-08-12 条目）；开源生态（ComfyUI 等第三方工具）不在本档案范围。
The platform includes Brand Studio (2026-04-08 entry: a brand-oriented creative production platform); the enterprise-integration line (Amazon Bedrock 2025-09-18 entry, NVIDIA NIM 2025-08-12 entry); the open-source ecosystem (ComfyUI and other third-party tools) is out of this dossier's scope.
上下文与记忆Context & memory: 生成为任务制，无跨会话记忆形态；每次生成独立，风格延续靠提示词与平台内的资产库（Brand Studio 素材），不是会话记忆。
Generation is task-based, no cross-session memory form; each generation is independent, style continuity relies on prompts and in-platform asset libraries (Brand Studio materials), not session memory.
权限与限制Permissions & limits: 官方 ToS：用户可选择退出把内容用于训练（opt-out 机制在条款内写明）；平台对上传内容取得运营所需许可。开源权重模型的训练数据口径见官方模型卡与基准报告。
Official ToS: users can opt out of having their content used for training (the opt-out mechanism is written into the terms); the platform takes operationally necessary licenses over uploaded content. Training-data stance for the open-weight models is in the official model cards and benchmark reports.
适合什么任务Best for: 想要「平台服务 + 可自托管开源模型」两条线都摸得到的人。商用条款平台版与开源版不同，分开读；对训练数据合规敏感的场景可关注其「全授权数据训练」口径的音频线。
People who want both lines within reach: "platform service + self-hostable open models". Commercial terms differ between the platform and open versions — read them separately; scenarios sensitive to training-data compliance may note its audio line's "fully licensed data" stance.

头号误解Top misconception

把平台 ToS 套到自托管开源模型——两套许可证体系，商用路径完全不同Applying the platform ToS to self-hosted open models — two license systems, completely different commercial paths
以为开源权重可以任意商用——各模型许可证不同（社区/企业许可线），逐模型核对Assuming open weights are freely commercial — licenses differ per model (community/enterprise license lines); check model by model
把「可退出训练」记成 Midjourney 式无开关——Stability 的 opt-out 写在条款里Remembering “training opt-out available” as Midjourney-style no-switch — Stability's opt-out is written into the terms
