Opera 发布 WebAI，将本地AI模型带入它的浏览器

在 Google 上的首选来源中添加 Unite.AI

2026年10月27日，Opera 宣布开始将本地AI模型直接运入其浏览器，使运行在用户自有计算机上的AI成为下一代Opera浏览器的中心部分。 首批能力作为Opera One的首选早期预览提供，歌剧院GX和歌剧院Neon将随之而来。

What WebAI 包含在发布中

WebAI是一种拟议的网络标准，根据Opera的说法，由Google和Microsoft等公司支持，并让网站和浏览器扩展使用通过浏览器托管的AI. Opera将其实施描述为模型不可知并围绕开放模型而构建，为用户提供AI提供者的选择。 在发布上，用户可以从Google和Apple上挖掘出模型，包括Google的Gemma和在Macs上，Apple的端侧基础模型，直接出演歌剧。 Opera 称 WebAI让任何人生成文本，对内容进行分类，并理解信息块的关联性，全部在浏览器内。

Krystian Kolondra, Opera的EVP浏览器和AI，将发行设定在消费者硬件已经可以处理的地方。 “人们从AI那里想要的很多东西不需要数据中心。 您的笔记本电脑已经可以做到这一点，而不将您的数据发送到任何地方，"他称。 科隆德拉称 Opera公司于2024年首先将本地模型运至开发商，现在正在将它们带给所有人，并补充说更多的模型和工具即将到来，用户将永远决定在他们的机器上运行什么。

更早的作品开始于2024年4月3日的一则公告，当时歌剧院从大约50个模型家庭加入了150个当地LLM变体的实验支持到歌剧院一号开发者流，包括Meta的Llama，维库纳，Google的Gemma，和Mistral AI的Mixtral. 每个变体通常需要2到10GB本地存储，本地模型补充了Aria,Opera的在线浏览器AI服务。 Opera描述2024开发商的建设使其成为第一个内置访问本地AI模型的主要浏览器。

控件、 API 和示例扩展

WebAI是可选入：在用户在Sets中打开之前，不下载任何内容，可以随时关闭，特定站点权限让用户决定哪些网站可以访问本地AI. 根据Opera的开发者博客文章，本地推论被构建到浏览器中，因此没有单独的AI应用程序可以安装，没有本地服务器可以配置，也没有API密钥可以获取。 WebAI 与 Opera 推论引擎提供的开放量级模型以及用户设备上已经兼容的模型合作，因此用户不会被绑在单一的模型提供者上。

Opera 称设计意味着用户不需要AI订阅，本地AI处理的信息会留在他们的设备上，而开发者可以在不运行AI基础设施或支付每个请求时添加AI功能。 公司给出了一个扩展的例子，可以对标签进行排序，标出点击程序，或者在用户的笔记本电脑上使用一个模型来查看相关的职位，没有账号，没有收费，也没有数据发送给AI服务。

WebAI 推出即"即时","决定"和"语义化" Embeddings APIs,Opera将其描述为生成文本，分类信息，并查找内容片段间关系的构件。 Opera的WebAI开发者页面还列出汇总器，Writer, Rewriter, Transfer and Proofreader API，游戏场在浏览器中完全运行于端侧。

为了展示开发者可以构建什么，Opera 发布 6 个实验性实例扩展被描述为思想启动者而不是歌剧院的功能：Project Lens，将文章的段落以每篇内容对一个被描述的项目有多重要来表示；Got It？它写了一篇关于刚刚读过的文章的快速问答；有疑问的智能，提出了关于一页的游戏性问题，并将判决画作为图表；语义艺术，将一篇具有类似句子的移动艺术变成视觉邻居；Record In Alchemy，将任何一篇文章变成歌剧院所称的令人难以忍受的启发性社交媒体文章；C-I-A-O，其中两个ASCII猫在任何主题上即兴起一幕。

可用性和平台限制

WebAI作为选入的早期预览，在有Intel或AMD处理器的64位Windows个人电脑上和有Apple硅的Macs上都可以使用。 它在基于Intel的Macs上，Linux上，或武装上Windows上都没有。 在设置中启用WebAI下载一个相容的本地模型，一个步骤 Opera 称可能需要几分钟。 由于AI运行在用户自己的设备上，Opera 称的性能依赖于硬件，并且会继续努力使本地AI更轻快。 公司将发布描述为更广泛的推力的起步，称计划为不同的设备带来更优化的开放模型，同时在本地AI上建立浏览器体验的更多工具。

HTML- in- Canvas 发布并列

同样在2026年10月27日，Opera 发布 HTML-in-Canvas，一种将真实，互动的网页放入2D和3D场景的网络能力。 Opera 称 canvas内容此前仅作为无法被点击，打入或选择的像素提供；使用HTML-in-Canvas，菜单，按钮，和表格可以随场景移动并仍然工作，由HTML和CSS开发人员已经知道。 Opera以商店，目录，设置，聊天等游戏界面为目标展示能力，Opera GX则以游戏者浏览器为对象展示能力。 公司称于2006年帮助将Canvas带入网络，后在WebGL上工作。

GX产品总监称 Maciej Kocemba。 “你可以拿一个真实的网页，把它扔入一个3D世界，一切仍然有效：按钮、文字、菜单、全部。 我们想让用户早点拿起

歌剧的演示包括网页推土机，推土机将真实的网页文本，图像和按钮推入堆；Gamer Room，一个3D游戏室，其屏幕是活的，交互式的网页；以及HTML Ninja，外加8个效果演示。 根据Opera的HTML-in-Canvas博客文章，该能力是在Chromium的开放中开发并实施的新兴网络平台提案；同源规则适用，因此开发者可以将自己的内容引入canvas，但不能被其他网站。 一个早期的 Bird 设置可以使 HTML-in-Canvas 横跨网络，演示在没有设置的 Opera 浏览器中工作。

Opera Launches WebAI, Bringing Local AI Models to Its Browsers

Add Unite.AI to your preferred sources on Google

Opera announced on October 27, 2026, that it began shipping local AI models directly in its browsers, making AI that runs on a user’s own computer a central part of the next generation of Opera browsers. The first capabilities are available as an opt-in early preview in Opera One, with Opera GX and Opera Neon to follow.

What WebAI Includes at Launch

WebAI is a proposed web standard that, according to Opera, is backed by companies such as Google and Microsoft and lets websites and browser extensions use AI hosted through the browser. Opera describes its implementation as model-agnostic and built around open models, offering users a choice among AI providers. At launch, users can tap models from Google and Apple, including Google’s Gemma and, on Macs, Apple’s on-device foundation model, directly in Opera. Opera says WebAI lets anyone generate text, classify content, and understand how pieces of information relate, all within the browser.

Krystian Kolondra, Opera’s EVP Browsers and AI, framed the release around what consumer hardware can already handle. “A lot of what people want from AI doesn’t need a data center. Your laptop can already do it, without sending your data anywhere,” he said. Kolondra said Opera first shipped local models to developers in 2024 and is now bringing them to everyone, adding that more models and tools are coming and that users will always decide what runs on their machine.

That earlier work began with an April 3, 2024 announcement, when Opera added experimental support for 150 local LLM variants from approximately 50 model families to the Opera One developer stream, including Meta’s Llama, Vicuna, Google’s Gemma, and Mistral AI’s Mixtral. Each variant typically required 2 to 10 GB of local storage, and the local models complemented Aria, Opera’s online browser AI service. Opera describes the 2024 developer build as making it the first major browser with built-in access to local AI models.

Controls, APIs, and Example Extensions

WebAI is opt-in: nothing is downloaded until the user turns it on in Settings, it can be turned off at any time, and site-specific permissions let users decide which websites can access local AI. According to Opera’s developer blog post, local inference is built into the browser, so there is no separate AI app to install, no local server to configure, and no API key to obtain. WebAI works with open-weight models provided through Opera’s inference engine and with compatible models already on the user’s device, so users are not tied to a single model provider.

Opera says the design means users do not need AI subscriptions and that information the local AI handles stays on their device, while developers can add AI features without running AI infrastructure or paying per request. The company gives the example of an extension that could sort tabs, flag clickbait, or spot relevant job posts using a model on the user’s laptop, with no account, no fee, and no data sent to an AI service.

WebAI introduces the Prompt, Decision and Semantic Embeddings APIs, which Opera describes as building blocks for generating text, classifying information, and finding relationships between pieces of content. Opera’s WebAI developer page also lists Summarizer, Writer, Rewriter, Translator and Proofreader APIs, with playgrounds that run entirely on-device in the browser.

To demonstrate what developers can build, Opera released six experimental example extensions it describes as idea starters rather than Opera features: Project Lens, which colors an article’s paragraphs by how much each matters to a stated project; Got It?, which writes a quick quiz about an article just read; Questionable Intelligence, which asks playful questions about a page and draws the verdict as a chart; Semantic Art, which turns an article into moving art with similar sentences becoming visual neighbors; RecordIn Alchemy, which turns any article into what Opera calls an insufferably inspirational social media post; and C·I·A·O, in which two ASCII cats improvise a scene on any topic.

Availability and Platform Limits

WebAI is available as an opt-in early preview on 64-bit Windows PCs with Intel or AMD processors and on Macs with Apple silicon. It is not available on Intel-based Macs, Linux, or Windows on Arm. Enabling WebAI in Settings downloads a compatible local model, a step Opera says may take a few minutes. Because the AI runs on the user’s own device, Opera says performance depends on the hardware and that it will keep working to make local AI lighter and faster. The company describes the launch as the start of a broader push and says it plans to bring more open models optimized for different devices, along with more tools for building browser experiences on local AI.

HTML-In-Canvas Launches Alongside

Also on October 27, 2026, Opera launched HTML-in-Canvas, a web capability that places real, interactive web pages inside 2D and 3D scenes. Opera says canvas content was previously rendered only as pixels that could not be clicked, typed into, or selected; with HTML-in-Canvas, menus, buttons, and forms can move with a scene and still work, built with the HTML and CSS developers already know. Opera presents the capability as aimed at game interfaces such as shops, inventories, settings, and chat, and at Opera GX, its browser for gamers. The company says it helped bring Canvas to the web in 2006 and later worked on WebGL.

“Honestly, this is a fun one,” said Maciej Kocemba, Product Director of Opera GX. “You can take a real web page and throw it into a 3D world, and everything still works: buttons, text, menus, all of it. We wanted users to get their hands on it early and see what they come up with.”

Opera’s demos include Webpage Bulldozer, in which a bulldozer pushes a real web page’s text, images, and buttons into piles; Gamer Room, a 3D gaming room whose screens are live, interactive web pages; and HTML Ninja, plus eight effects demos. According to Opera’s HTML-in-Canvas blog post, the capability is an emerging web platform proposal developed in the open and implemented in Chromium; same-origin rules apply, so developers can draw their own content into a canvas but not other websites. An Early Bird setting enables HTML-in-Canvas across the web, and the demos work in Opera browsers with no setup.
