Model Card｜Xing4.0-29B-A4B
Xing4.0-29B-A4B (China Telecom Artificial Intelligence Technology / XingChen-AGI, successor to TeleChat): 29B total parameters with only 4B active, 256K native context (extensible to 512K), Apache-2.0 open source. Scores 75.0 on SWE-bench Verified (vs. 76.0 for the larger Qwen3.6-35B-A3B and 53.0 for Gemma4-26B-A4B) and 57.5 on Terminal-Bench 2.1, the highest of the three. It's the first model at this scale trained entirely from scratch on Ascend 910C + MindSpore, with training throughput improved roughly 96% over an unoptimized baseline.
