> iFlyTek Spark Open
spark-api-open.xf-yun.com is the OpenAI-compatible HTTP endpoint for iFlyTek's Spark (讯飞星火) LLM. It provides access to multimodal models via the iFlyTek Open Platform. A permanently free 'Lite' version is available for developers.
// pros
- First-party vendor endpoint (iFlytek, a listed Chinese company)—not a third-party relay, no stolen-upstream-key risk
- Spark Lite is officially declared permanently free with unlimited tokens, suitable for sustained low-cost use
- OpenAI-compatible HTTP endpoint (spark-api-open.xf-yun.com/v1/chat/completions) alongside the legacy WebSocket API
- Low latency from mainland China (164ms probed), complete Chinese docs, clear legal entity
// cons
- This host is only an API endpoint and returns 401 on probe; you must register, complete real-name verification, and create an app on xfyun.cn to get an APIPassword
- Spark Lite is a lightweight, weaker model; stronger tiers (Pro/Max/4.0 Ultra) become paid once the gifted tokens run out
- The free tier is QPS-limited (typically ~2 concurrent streams), unsuitable for high-concurrency production
- Requires a mainland-China phone number/real-name KYC; anonymous or overseas use is constrained, and content is subject to domestic compliance monitoring
As a first-party Chinese vendor free tier, it suits lightweight Chinese-language workloads (summarization, classification, RAG Q&A) and personal projects; create an app on xfyun.cn to obtain the APIPassword, mind the Lite-vs-paid quota split, QPS caps, and KYC/compliance requirements, and don't treat gifted tokens as a long-term guarantee.
community_reputation
The iFlytek Open Platform is a mainstream first-party Chinese LLM platform; many community tutorials (CSDN, Zhihu, cnblogs) treat Spark Lite as the go-to entry-level 'free LLM API' and confirm it is permanently free for lightweight tasks such as summarization and RAG. Negative feedback centers on Lite's limited capability, low QPS, and KYC requirements—not on exit-scam or key-theft risks.

Free tier present — value not quantified
This provider offers a free tier, but its terms don’t convert cleanly into a USD figure (e.g. request-count limits or capacity-dependent pools). We refuse to print a misleading zero here. See the note below and the official pricing page for the exact limits.
note: Spark Lite (model=lite) permanently free since May 2024: unlimited tokens, QPS caps only - unquantifiable; one-off token packs for other tiers (~2M tokens ~ $2, promo-dependent); real-name registration required.
