iFLYTEK released the Spark X2.6 large model with an edge-cloud integrated architecture at the 2026 Global 1024 Developer Festival on October 22, simultaneously launching the edge-side model Spark X2.6-4B. This release emphasized the edge-cloud integrated architecture, where the system can complete tasks using pure edge-side, pure cloud-side, or edge-cloud collaborative methods based on task routing.

The edge-side model Spark X2.6-4B can locally process tasks such as email summarization and sensitive information desensitization in contracts, which are then reviewed and revised by the cloud-side model. Liu Qingfeng, Chairman of iFLYTEK, estimates that approximately 60% of application scenarios will be completed on the edge side in the future, 30% through edge-cloud collaboration, and 10% requiring cloud-side large models. The company stated that the proportion of tasks independently completed on the edge side has increased from 12.8% to over 40%.

In terms of model capabilities, Spark X2.6 adopts a Mixture-of-Experts (MoE) architecture with 293B total parameters and 30B active parameters, and its context window has been expanded to 1 million tokens. API pricing shows that X2.6 is currently offered at a 40% discount for a limited time, with input and output prices of 0.9 yuan and 3.6 yuan per million tokens, respectively. Based on the discount, the pre-discount output price is approximately 6 yuan. The previous generation X2.5 is currently offered at a 70% discount for a limited time, with input and output prices of 0.96 yuan and 3.6 yuan per million tokens, respectively, and a pre-discount output price of approximately 12 yuan. Additionally, iFLYTEK also released several other products, including the SparkAudio 1.0 large speech foundation model.
