适合与不适合When to use it, when not to

适合：已在 Meta 系应用内工作、要免费对话+图像生成。不适合：要脱离 Meta 账号、要大陆直连、要权重在产品内本地跑。

Fits: already working inside Meta apps (WhatsApp/IG), free chat + image generation. Not a fit: leaving the Meta account, direct mainland access, running weights locally inside the product.

中文生态China availability 国产 / 国内可直接用 / 备案状态 · 快照domestic / direct access / CAC filing · snapshot 2026-10-30

出品属地Origin: 国外出品foreign-made　国外主体（Meta，美国；网信办公示名单未见对应备案主体）。foreign entity (Meta, USA; no matching filing entity in the CAC registry).
国内使用Direct access: 直连不可达direct blocked　www.meta.ai 大陆直连 000（网络不可达，2026-10-30）；Meta 系服务在大陆整体不可用的既有口径一致。www.meta.ai measured 000 direct from mainland (network unreachable, 2026-10-30); consistent with the long-standing unavailability of Meta services in the mainland.
备案状态CAC filing: 未见于备案名单not in filing list：未见于网信办公示名单（2026-10-30 检索百炼公示页与批次 PDF 镜像，未见 Meta 条目）；该产品未面向大陆公众提供服务，备案不适用。not in the CAC public registry (Bailian disclosure page and batch PDF mirrors searched 2026-10-30; no Meta entry); the product does not serve the mainland public, so filing does not apply.

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.

固定坐标系Fixed coordinate system

8 个维度dimensions, 与同分区其他对象逐项可比each comparable item by item against others in the same section.

模型与开放条件Model & openness: 底座是 Meta 自研 Llama 系（开放权重族——权重下载自部署是另一条线，见 models 站 Llama 系列档案）；产品内模型版本与切换形态未逐条核验。
The base is Meta's self-developed Llama family (an open-weights family — downloading weights to self-deploy is a separate line, see the Llama series entries on the models site); in-product model versions and switching form not verified item by item.
运行位置Where it runs: 网页（meta.ai）+ App，且深度嵌入 WhatsApp/Instagram/Facebook/Messenger 内的 AI 入口；生成在 Meta 云端，本机不跑模型。当日 www.meta.ai 对无头抓取 403（Cloudflare 拦截，非死链）。
Web (meta.ai) + apps, deeply embedded as AI entries inside WhatsApp/Instagram/Facebook/Messenger; generation runs on Meta's cloud, nothing runs locally. www.meta.ai returned 403 to headless fetching on the day (Cloudflare block, not a dead link).
本地文件Local files: 对话历史存于 Meta 账户侧、与社交图谱同账号体系；未见官方声明的本机数据面—— 权重开放可下载自部署是另一条线（见 models 站 Llama 系列档案），产品对话数据不随权重落在本机。
Chat history stored on the Meta account side, under the same account system as the social graph; no locally-held data surface declared by the vendor — downloadable open weights for self-deployment is a separate line (see the Llama family entries on the models site); product chat data does not land on your machine with the weights.
关机后的任务Tasks after shutdown: 对话即时返回；异步任务形态未核验到官方声明。嵌入 WhatsApp/IG 等应用内的入口与独立站（meta.ai）的会话是否互通、历史如何联动，未逐条核验。
Chat returns instantly; no official statement verified for an async-task form. Whether sessions interoperate between the in-app entries (WhatsApp/IG) and the standalone site (meta.ai), and how histories link, was not verified item by item.
工具与扩展Tools & extensions: 图像生成（Imagine 线）、联网等能力在官方叙事在册；MCP 支持未核验到官方声明。
Image generation (the Imagine line), web and other capabilities are on record in the official narrative; no MCP support verified in official statements.
上下文与记忆Context & memory: 会话按对话组织、跨 Meta 系应用的历史联动形态未逐条核验；跨会话记忆机制未核验到官方声明。
Chats organized per conversation; cross-app history linkage across Meta surfaces not verified item by item; no official statement verified for cross-session memory.
权限与限制Permissions & limits: Meta 账号体系（与社交图谱同账号是它的最大权限面）；训练用途开关路径未逐条核验—— Meta 的数据使用口径历来敏感，要按官方隐私页逐项看。
Meta account system (sharing one account with the social graph is its biggest permission surface); training-usage toggle path not verified item by item — Meta's data-use terms have historically been sensitive, read the official privacy page item by item.
适合什么任务Best for: 适合：已在 Meta 系应用（WhatsApp/IG）内工作、要免费对话+图像生成的用户。不适合：要脱离 Meta 账号、要大陆直连（未备案）、要权重在产品内本地跑。
Fits: users already working inside Meta apps (WhatsApp/IG), wanting free chat + image generation. Not a fit: leaving the Meta account, direct mainland access (not filed), running weights locally inside the product.

头号误解Top misconception

Meta AI（www.meta.ai 对话助手）与 coding 大类的 meta-muse（编码云）是两条产品线——inventory 登记时已注明，别混Meta AI (www.meta.ai chat assistant) and meta-muse in the coding category (coding cloud) are two product lines — noted at inventory registration, do not merge them
「Llama 开放权重」不等于「Meta AI 可本地跑」——产品跑在 Meta 云上，权重线是下载自部署"Llama open weights" does not mean "Meta AI can run locally" — the product runs on Meta's cloud; the weights line is download-and-self-deploy
Meta AI 嵌在 WhatsApp/IG 里=同一账号体系的数据联动——敏感使用要单独想清楚Meta AI embedded in WhatsApp/IG = data linkage under one account system — think it through separately before sensitive use

实测记录Measured runs

本档未跑对话任务集；能力结论来自官方文档，不评价回答质量。

实测建议（三条，都指向官方可读页没给的东西）：

产品内模型版本与切换形态（Llama 版本迭代在产品侧怎么呈现）
训练用途开关路径与默认态（Meta 数据使用口径敏感，逐项看官方隐私页）
跨 WhatsApp/IG/meta.ai 的历史联动边界

This site has not completed measured runs. The coding-oriented test protocol is at protocols/coding/_protocol.md (the coding task suite does not apply to chat products).

Suggested measurements (three, all pointing at things the official readable pages do not give):

In-product model versions and switching form (how Llama version iterations surface on the product side)
Training-usage toggle path and default state (Meta's data-use terms are sensitive; read the official privacy page item by item)
History-linkage boundaries across WhatsApp/IG/meta.ai
