iFLYTEK (SparkLLM)Proprietary

iFLYTEK / SparkLLM's cloud flagship Mixture-of-Experts model in the Spark X2.5 family (announced Sep 7, 2026). 293B total / 30B activated parameters with a 256K (262,144-token) context; multilingual text generation across 200+ languages, focused on coding and agent capabilities with continued math/understanding gains, trained and served on domestic Chinese compute via the xfyun MaaS platform. MaaS list pricing is published in CNY only (input CNY1.6 / 1M, cache-hit CNY0.24 / 1M, output CNY6 / 1M); no first-party USD table, so token prices are left blank here. Distinct from the open-weight Apache-2.0 edge siblings Spark-X2.5-4B and Spark-X2.5-1.7B.
