RECATOOLS Verdict

Spark is a credible, cheaply priced Chinese model line with real strengths in speech, education and healthcare, and the September 2026 open release of X2.5-4B and 1.7B gives developers small Apache 2.0 models with a one-million-token context. The X2.5 API, at ¥1.60 in and ¥6.00 out per million tokens on a half-price offer, is inexpensive.

Its benchmark claims are iFlytek's own, the assistant needs a mainland phone or WeChat login, and billing and data sit in China. A good choice inside China's education and voice ecosystems; outside them, the open small models are the most useful part.

What we found

Spark (讯飞星火) is the large-model line of iFlytek, the Hefei speech-recognition company, and it covers a consumer assistant on web and mobile, an API platform and a set of industry models for education, healthcare and car cockpits. The assistant is free to use with a mainland phone number or WeChat login; no paid consumer plan appeared on the pages read.

The model line moved twice in 2026. Spark X2, launched on 11 February, is a 293-billion-parameter mixture-of-experts model that iFlytek says was trained on domestic Chinese computing power and, once quantised, runs on a single Huawei Ascend server. iFlytek claims it matches the best international models in maths, reasoning and agent tasks, and that inference runs 50% faster than the previous X1.5. Those are vendor claims on vendor test sets. Spark X2.5 followed on 7 September, keeping the 293-billion size with about 30 billion active, a 256K context, more than 200 languages and a stated focus on coding and agents.

A week earlier, iFlytek's subsidiary 词元星火 open-sourced two small models, Spark X2.5-4B and 1.7B, under Apache 2.0 on Hugging Face and GitHub. Both accept up to a million tokens of context, which the Science and Technology Daily described as a first for on-device models, and both run on Nvidia, Huawei and other hardware through vLLM, llama.cpp or Ollama.

API prices are low and published in yuan. Spark X2.5 is listed at ¥1.60 per million input tokens and ¥6.00 per million output, marked as a limited-time half-price offer; X2 costs ¥3 per million and X2-Flash ¥1 to ¥2. The 1.7B model's API is free and the 4B's free for a limited time. The same platform also resells GLM, Kimi and DeepSeek models.

For ASEAN teams the practical limits are the Chinese-first interface, mainland login, yuan billing and data held in China. Spark is most compelling where iFlytek's speech and education strengths matter, or for the small open models.

Frequently asked questions

Entirely Huawei Ascend compute, with no Nvidia in the loop — which is what makes Spark strategically important to China's domestic-silicon push.
No, and it does not need to be. Leaderboards put DeepSeek, Qwen, GLM and Kimi ahead as generalists; Spark's edge is Mandarin voice interaction and multimodal speech, built on two decades of speech-recognition heritage.
Education, healthcare and automotive-cockpit work inside China, with API access through iFlytek's platform and official SDKs on GitHub.
