科大讯飞iFlytek

国产China-origin 免费+登录Free + sign-in 语音强项Speech-focused 教育向Education-focused 已备案Filed partial lifecycle: active 核验Checked 2026-10-22

讯飞星火是语音底座突出的国产对话产品（讯飞自研星火系列，语音识别/合成/同传是传统强项）：教育/办公场景友好，首批备案（2023-08-23）；星火主线不开源权重。

iFlytek Spark is the domestic chat product with a strong voice foundation (iFlytek's self-developed Spark series; recognition/synthesis/interpretation are traditional strengths): education/office friendly, first-batch filed (2023-08-23); the Spark line does not open its weights.

适合与不适合When to use it, when not to

适合：语音交互密集、中文问答解题、教育办公文档。不适合：要本机跑模型、要脱离讯飞账号。

Fits: voice-heavy interaction, Chinese Q&A and problem-solving tutoring, education/office documents. Not a fit: running models locally (Spark weights closed), leaving the iFlytek account.

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: 主力是科大讯飞自研星火（Spark）系列——官方有版本迭代线（V 系列版本号在官方新闻页可查）；讯飞开放平台（xfyun.cn）是开发者 API 线，同厂商另一接口。应用内模型档位以登录后界面为准。
The main line is iFlytek's self-developed Spark series — there is an official version-iteration line (V-series version numbers are findable on the official news page); the iFlytek Open Platform (xfyun.cn) is the developer API line, another interface from the same vendor. In-app model tiers are per the signed-in UI.
运行位置Where it runs: 网页（xinghuo.xfyun.cn）+ iOS/Android App + PC 客户端；生成在讯飞云端处理，本机不跑模型。星火主线不开源权重（与 DeepSeek/GLM/Qwen 不同）。
Web (xinghuo.xfyun.cn) + iOS/Android apps + PC client; generation is processed on iFlytek's cloud, no model runs locally. The Spark main line does not open-source its weights (unlike DeepSeek/GLM/Qwen).
本地文件Local files: 对话历史存于账户侧；文档/图片解析在云端进行。未见官方声明的本机数据面。
Chat history is stored on the account side; document/image parsing happens in the cloud. No locally-oriented data surface declared by the official side.
关机后的任务Tasks after shutdown: 对话即时返回；异步任务队列形态未核验到官方声明。产品含「深度研究」类长任务能力线（官方新闻页叙事），执行是否可离开页面续跑未核验。
Chats return instantly; no official statement verified for an async task-queue form. The product includes a "deep research"-type long-task capability line (official news-page narrative); whether execution can continue after leaving the page is unverified.
工具与扩展Tools & extensions: 产品内含联网搜索、文档解析、AI 写作、解题答疑、深度研究等能力线（官网导航所见）；语音能力（识别/合成/同传）是讯飞的传统强项，在产品内是差异点。MCP 支持未逐条核验。
In-product capability lines incl. web search, document parsing, AI writing, problem-solving Q&A and deep research (seen in the official-site navigation); speech capabilities (recognition/synthesis/simultaneous interpretation) are iFlytek's traditional strength and a differentiator inside the product. MCP support not verified item by item.
上下文与记忆Context & memory: 会话历史登录同步；跨会话记忆机制未核验到官方声明（未知就说未知）。
Session history syncs when signed in; no official statement verified for a cross-session memory mechanism (if unknown, say unknown).
权限与限制Permissions & limits: 账号体系（手机号注册）；训练用途开关路径未逐条核验。星火模型备案号见 cn 块（官方公示交叉核验）。
Account system (phone-number registration); the training-use switch path not verified item by item. The Spark model filing number is in the cn block (cross-verified against official public disclosures).
适合什么任务Best for: 适合：语音交互密集场景（讯飞语音底座强）、中文问答+解题答疑、教育/办公文档场景。不适合：要本机跑模型（星火不开源权重）、要脱离讯飞账号。
Suits: speech-heavy scenarios (iFlytek's speech foundation is strong), Chinese Q&A + problem-solving, education/office document scenarios. Does not suit: running models locally (Spark does not open-source its weights), or leaving the iFlytek account.

头号误解Top misconception

把 xinghuo.xfyun.cn（对话产品）与讯飞开放平台 xfyun.cn（API/能力平台）混为一谈——同厂商两接口Mixing xinghuo.xfyun.cn (chat product) with the iFlytek open platform xfyun.cn (API/capability platform) — one vendor, two interfaces
把星火当开源权重族——星火主线不开源，「本地跑星火」这条线不成立Treating Spark as an open-weight family — the Spark line keeps weights closed; 'run Spark locally' is not a viable path
语音强项是讯飞底座——但「语音能力」在产品内的具体形态（实时同传/声音复刻）要按官方页逐项核，别整块照搬宣传Voice strength is iFlytek's foundation — but each in-product voice capability (live interpretation, voice cloning) must be checked item by item against official pages; don't copy the marketing block wholesale

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）：

应用内模型档位选择器实际形态（登录后才可见）
训练用途开关路径与默认态
「深度研究」长任务能否离开页面续跑（异步边界未核验）

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):

The actual form of the in-app model tier selector (only visible after signing in)
The training-use switch path and default state
Whether the "deep research" long task can continue after leaving the page (the async boundary is unverified)
