Reka Chat（Reka Playground / Edge Chat）Reka Chat (Reka Playground / Edge Chat)
Reka Chat 是一家已整体转向 physical AI 的研究室留下的对话入口（app.reka.ai「Edge Chat」）： 公司当日招牌是 omni 模型、Reka Cloud、视频与数据基础设施；对话产品面薄，真正的可核验面在 API（OpenAI 兼容、自家 Edge/Flash+精选开源档）与 Reka Edge 开放权重本机路线。
Reka Chat: a chat entry left behind by a lab that fully pivoted to physical AI — the homepage's marquee today is omni models, Reka Cloud, and video/data infrastructure; the chat surface (app.reka.ai "Edge Chat") is thin, and the verifiable surface is the API (OpenAI-compatible; in-house reka-edge-2603/reka-flash-3 + curated open tiers deepseek4-flash/glm5.3/qwen3.8-27b/gemma4-26b) plus the Reka Edge open-weights local route. Key wording: the company's mainline is world-model research (news line: Rho-1 2026-10-05) — reading Reka as a "chat product company" misplaces it.
适合与不适合When to use it, when not to
适合：跟 Reka 模型线、经一家 API 横排精选开源档、要 Edge 开放权重本机路线。 不适合：要成熟 C 端对话产品、要大陆直连对话服务。
Fits: following the Reka model line (Edge/Flash), lining up curated open tiers through one API, the Edge open-weights local route. Not a fit: mature consumer chat products; mainland-direct chat service (not filed).

- 出品属地Origin
- 国外出品foreign-made 国外主体（Reka AI, Inc.，美国；前 DeepMind 团队创立——nav 旧条目口径，官方页未自述创始背景，按 nav 交叉标注）。foreign entity (Reka AI, Inc., USA; founded by an ex-DeepMind team — carried from the older nav entry; the official pages do not state the founding background, noted as nav cross-reference).
- 国内使用Direct access
- 大陆可直连direct OK reka.ai 大陆直连 200（2026-10-31 直抓核验，www 308→裸域）；app/docs 子域同直连可达。reka.ai measured 200 direct from mainland (fetched 2026-10-31, www 308 to apex); app/docs subdomains also reachable direct.
- 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（2026-10-31 检索公示页与批次清单，未见 Reka 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 (disclosure page and batch lists searched 2026-10-31; no Reka 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.

- 模型与开放条件Model & openness
自家模型+精选开源模型双池：Reka API 当日在册模型表含 reka-edge-2603（16k 上下文、文本/图像/视频输入）、 reka-flash-3（64k）与 deepseek4-flash/glm5.3/qwen3.8-27b/gemma4-26b 等开源档，全部经 api.reka.ai/v1 OpenAI 兼容端点调用；对话入口（app.reka.ai「Edge Chat」）与其 API 池的关系未逐条核验。
Dual pool of in-house models + curated open models: the Reka API model table verified same day lists reka-edge-2603 (16k context, text/image/video input) and reka-flash-3 (64k) alongside open tiers such as deepseek4-flash/glm5.3/qwen3.8-27b/gemma4-26b, all called through the api.reka.ai/v1 OpenAI-compatible endpoint; how the chat entry (app.reka.ai "Edge Chat") relates to the API pool was not verified item by item.
- 运行位置Where it runs
网页入口 app.reka.ai（chat.reka.ai 307→app.reka.ai/chat，当日核验；页内标题「Reka Playground / Edge Chat」）； 另有 API（api.reka.ai/v1）与开放权重本机路线（docs「Run locally」：macOS Apple Silicon 32GB+ / Linux 服务化）。
Web entry at app.reka.ai (chat.reka.ai 307→app.reka.ai/chat, verified same day; page title "Reka Playground / Edge Chat"); plus an API (api.reka.ai/v1) and an open-weights local route (docs "Run locally": macOS Apple Silicon 32 GB+ / Linux serving).
- 本地文件Local files
托管对话数据口径按官方隐私页（2026-06 版当日在册）管辖，未逐条核验；开放权重 Reka Edge 下载后 完全在本机运行（docs run-locally 页在册）——托管入口与本机权重是两条数据边界。
Hosted chat data is governed by the official privacy policy (June 2026 version verified same day), not verified item by item; the open Reka Edge weights run entirely on your own machine once downloaded (docs run-locally page on record) — hosted entry and local weights are two data boundaries.
- 关机后的任务Tasks after shutdown
对话即时返回；异步/代理任务形态未核验到官方声明。公司现行主线是 research/Reka Cloud/视频基础设施/数据基础设施 （官网首页当日四段自述），对话入口不在首页招牌区。
Chat returns immediately; no official statement verified for async/agentic task forms. The company's current mainline is research/Reka Cloud/video infrastructure/data infrastructure (four self-described sections on the homepage verified same day); the chat entry is not in the homepage's marquee area.
- 工具与扩展Tools & extensions
API 侧工具面在册：模型表标注 Tools/Structured outputs/Reasoning 三列（reka-edge-2603 三项全 Yes； reka-flash-3 Tools=No）；文档站自带 MCP server（docs.reka.ai/_mcp/server，llms.txt 在册）供 agent 接文档。
API-side tooling surface on record: the model table carries Tools/Structured outputs/Reasoning columns (reka-edge-2603 Yes on all three; reka-flash-3 Tools=No); the docs site ships its own MCP server (docs.reka.ai/_mcp/server, on record in llms.txt) for agents to read the docs.
- 上下文与记忆Context & memory
会话按对话组织；跨会话记忆机制未核验到官方声明。API 侧上下文长度随模型不同（当日表：reka-edge-2603 16k、 reka-flash-3 64k、开源档 262k），对话入口实际生效值未核验。
Conversations are organized per chat; no cross-session memory mechanism verified in official statements. On the API side context length varies by model (table same day: reka-edge-2603 16k, reka-flash-3 64k, open tiers 262k); the effective value in the chat entry was not verified.
- 权限与限制Permissions & limits
账号制（app.reka.ai 需登录）；条款主体 Reka AI, Inc.（Terms of Use 2026-09：合同约束 reka.ai 及 vision/creator/developer 子域与 Reka Labs/Cloud/Vision 服务）；隐私页 2026-06 版含 EEA/UK 专章。
Account-gated (app.reka.ai requires login); contracting party Reka AI, Inc. (Terms of Use 2026-09: the contract covers reka.ai and its vision/creator/developer subdomains plus Reka Labs/Cloud/Vision services); the privacy page (June 2026) carries an EEA/UK section.
- 适合什么任务Best for
适合：跟 Reka 自家模型线（Edge/Flash）+想经一家 API 横排精选开源档（DeepSeek/GLM/Qwen/Gemma）； 要 Reka Edge 开放权重本机路线。不适合：要成熟 C 端对话产品（入口面薄、公司重心已转向 physical AI）； 要大陆直连对话服务（未备案）。
Fits: following the Reka in-house model line (Edge/Flash) + lining up curated open tiers (DeepSeek/GLM/Qwen/Gemma) through one API; wanting the Reka Edge open-weights local route. Not a fit: wanting a mature consumer chat product (thin entry surface, company focus has shifted to physical AI); wanting mainland-direct chat service (not filed).
头号误解Top misconception
- 公司定位已整体转向——官网当日招牌是「models and infrastructure for the physical AI era」（omni 模型/Reka Cloud/视频基础设施/egocentric 数据），news 主线是 world model 研究（Rho-1 2026-10-05 等）；对话入口只是角落产品，按「对话产品公司」理解会错位The company positioning fully pivoted — the homepage marquee is "models and infrastructure for the physical AI era" (omni models/Reka Cloud/video infrastructure/egocentric data) and the news mainline is world-model research (Rho-1 2026-10-05 etc.); the chat entry is a corner product — understanding Reka as a "chat product company" misplaces it
- API 池含精选开源模型（deepseek4-flash/glm5.3/qwen3.8-27b/gemma4-26b）——「Reka API」不等于「只用 Reka 模型」，各开源档按其自身权重许可使用The API pool includes curated open models (deepseek4-flash/glm5.3/qwen3.8-27b/gemma4-26b) — "Reka API" does not mean "Reka models only"; each open tier is used under its own weights license
- Reka Edge 开放权重与闭源旗舰是两线——reka-edge-2603 可在本机跑（docs run-locally），reka-flash-3 仅 API；两线能力与数据边界不同Reka Edge open weights and the closed flagship are two lines — reka-edge-2603 runs locally (docs run-locally), reka-flash-3 is API-only; capabilities and data boundaries differ
- 对话入口功能面薄——app.reka.ai 为 JS 应用（当日仅见「Edge Chat」标题），模型选择/记忆/上传等功能未核验到官方文档；勿按 ChatGPT 类成熟度预期The chat entry's feature surface is thin — app.reka.ai is a JS app (only the "Edge Chat" title visible same day); model choice/memory/upload unverified in official docs; do not expect ChatGPT-class maturity

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，都指向官方页没给的东西）：
- Edge Chat 入口实际挂哪个模型、与 API 模型表是否一致（入口 JS 应用未核验）
- 托管对话数据的留存与训练口径（隐私页 2026-06 版逐项看）
- Reka Edge 权重本机跑的硬件门槛体验（docs 写 Apple Silicon 32GB+，实操未测）
This site has not completed measured runs. The coding test protocol is at protocols/coding/_protocol.md (the coding task set does not apply to chat products).
Suggested runs (three, each pointing at what the official pages do not give):
- Which model the Edge Chat entry actually serves, and whether it matches the API model table (the entry is a JS app, unverified)
- Retention and training-use terms for hosted chat data (read the June 2026 privacy policy item by item)
- Hands-on feel of the Reka Edge weights local hardware bar (docs say Apple Silicon 32 GB+, not actually tested)
