iFlytek Spark

Spark Lite is free to claim (iFlytek's own lightweight model); the platform now directly integrates third-party models like DeepSeek/Kimi/Qwen, most labeled 'free to claim'

The former Pro/Max/Ultra three-tier pricing has been replaced by the new Spark-X2.5 series; the official pricing page no longer shows any Pro/Max/Ultra or 'RMB 0.21 per 10,000 tokens' wording. The current page labels Spark Lite, Spark-X2.5-1.7B, and others as 'free,' and also integrates third-party models such as DeepSeek-V4-Pro/Flash and Kimi-K2 labeled 'free to claim' — whether this is a stable long-term policy or a limited-time promotion hasn't been verified item by item.

⚠️2026-09-18 re-check: the product lineup has been updated from the four Lite/Pro/Max/Ultra tiers to the Spark-X2.5 series plus a third-party model marketplace (DeepSeek/Kimi/Qwen, etc.); the official site no longer shows the former 'Pro/Max/Ultra RMB 0.21 per 10,000 tokens' wording, Spark Lite is still labeled 'free to claim,' and details like rate limits should be verified by logging into the console. The 'permanently free' claim applies to the Lite version; a rate limit of roughly 5 RPM is low and unsuited to high-concurrency scenarios. As of March 2026, the Max tier has been folded into Ultra, and the plan structure has changed.
