iFlytek releases the device-cloud integrated iFlytek Spark X2.6, trained on fully domestic computing power and paired with a 4B on-device model
At the 1024 Developer Festival, iFlytek released the device-cloud integrated iFlytek Spark X2.6, which pairs a cloud-based large model with a 4B on-device model and decides among local processing, device-cloud collaboration, or cloud offloading based on task difficulty and data sensitivity. The model is trained on fully domestic computing power; Liu Qingfeng said domestic computing power still lags Nvidia by nearly two generations, with the gap concentrated in memory and bandwidth. iFlytek says its 4B on-device model raised the completion rate on complex agent tasks from an industry figure of about 12% to 41.9%, with device-cloud routing accuracy of 96.1%.
