iFLYTEK unveils Spark X2.6 trained entirely on domestic compute, open-sources a 4B model
iFLYTEK
At its 1024 Developer Festival on October 22, 2026, iFLYTEK announced Spark X2.6, a 293B-total/30B-active MoE with a 1M-token context trained end to end on a 10,000-card domestic Ascend cluster. The cloud model is closed, but the on-device Spark X2.6-4B was released under Apache 2.0 on Hugging Face; the event also introduced SparkAudio 1.0, claiming 20% quality gains and 60% lower cost.
Why it matters
It is the clearest public claim that a Chinese frontier-class model was trained without NVIDIA hardware, and the Apache-2.0 4B gives the claim a downloadable artifact.
Importance: 3/5
notable release (major version, significant open-weights drop, or regulatory shift)
