What to build with Kunavo.
- Customer Support
AI customer support
The fastest-ROI AI deployment in any B2C SaaS — automate ticket triage, draft 80% of responses, and escalate the rest cleanly. Production code, real cost numbers, and the compliance pitfalls that catch teams off-guard.
Explore - Knowledge Base
RAG chatbot API
Most internal knowledge bases are dead documentation — nobody finds anything. A Claude-backed RAG chatbot turns them into a real assistant that cites sources and refuses when it doesn't know. Here's the production pattern.
Explore - Trust & Safety
AI content moderation
Modern moderation isn't just regex — it's nuance: sarcasm, dog whistles, brand-context misuse, image+text combinations. LLMs do this far better than rule-based systems, at a price that scales.
Explore - Developer Tools
AI code assistant
Cursor, Aider, Cline, Continue.dev — they're all powered by the same handful of frontier LLMs. If you're building a coding tool (or a co-pilot inside your own dev product), here's the architecture and the cost reality.
Explore - Data Processing
AI data extraction
The boring, valuable use case. Invoices, receipts, contracts, leads, resumes — anywhere you'd previously have built a parser, an LLM with JSON-mode does it in 30 lines, more accurately, and you can ship in a day instead of a quarter.

把你的 Agent 指向 llms.txt
它就能用上每个模型。
把一句话交给 Claude Code、Cursor、Cline 或任何 OpenAI 兼容的 Agent。它会自己读取 Kunavo 的实时模型目录，驱动文本、图像、视频模型。无需 SDK，无需胶水代码。
- OpenAI 线协议兼容 —— Agent 无需任何定制接入
- GET /v1/models 即实时目录 —— 无需硬编码模型名
- 一把密钥贯通全模态：文本、图像、视频、音频

日本語 RAG チャットボットを Claude で構築 — 5,000 文書のナレッジベースを 30 行で
社内ドキュメント 5,000 件を Claude Sonnet 4.6 で検索可能にする RAG 完全実装。埋め込みコスト $0.25、1 クエリ約 0.9 円（prompt caching 適用後）。日本語特有のトークン消費・ハルシネーション対策・本番投入チェックリスト含む。
Kunavo 专门为独立开发者和小团队的生产级 AI 功能设计。三个真实差异：(1) 文本、图像、视频统一计费 —— 大部分聚合平台只做文本；(2) Stripe 原生结账，ACH、SEPA、Apple Pay、微信支付全部支持，无需走线下发票；(3) 路由完全透明 —— 我们绝不偷换你的模型到更便宜的版本。
每个模型价格约为官方挂牌价的 3–7 折（立省 30–70%），充值越多额外赠送越多。再加上运营层面的省心：一份合同、一份发票、一套 SDK、无承诺最低消费。每个模型的 per-1M-token 价格在 /pricing 页直接公示，与上游官方价随时可对比。
是。我们实现了 /v1/chat/completions、/v1/embeddings、/v1/images/generations、/v1/models、/v1/video/generations 等完整 OpenAI 端点。Streaming、function calling、vision、tool use 全部行为一致。已经在用 OpenAI SDK 的项目改一行 base_url 即可迁移。
永不过期。Kunavo 是按调用扣费的预付钱包模式，余额永久保留，没有月费、没有最低消费、没有有效期限制。账户注销时余额按原支付方式退回。
不会。4xx 和 5xx 响应一律不计费。流式响应在中途断开时，只扣已生成部分。所有扣费在控制台「用量明细」按调用查看，支持导出 CSV 用于对账。
Stripe 支持的全部方式：信用卡（Visa、Mastercard、Amex、JCB、银联）、Apple Pay、Google Pay、Link、ACH、SEPA、BACS、BECS、Alipay、微信支付、Klarna、Afterpay 等。自动充值可按需开启。企业客户可申请月度发票（Net 30）。
边缘网关节点部署在北美、欧洲、亚太多个区域。无状态路由逻辑在边缘执行，全球 P50 时延 120ms 以内。账单数据、账户和审计日志存储于主区域并多区域复制。
