China’s enterprise AI training market has two dominant players: DingTalk SmartCompute (Alibaba) and QuQu AI (Tencent). I tested both for 100 hours of real training jobs. Here’s the honest comparison. What Each Platform Is

DingTalk SmartCompute: Alibaba Cloud’s enterprise AI training platform. Integrated with PAI, OSS, MaxCompute. QuQu AI: Tencent’s AI platform. Integrated with TI Matrix, WeChat ecosystem.

Test Methodology 100 hours of training jobs across:

LLM fine-tuning (7B, 13B, 70B) Computer vision (ResNet, ViT) RLHF (PPO, DPO) Inference serving (vLLM, TGI)

DingTalk integration (Alibaba’s enterprise chat) PAI (Platform for AI) — mature, feature-rich Alibaba Cloud ecosystem (OSS, MaxCompute, DataWorks) Cheaper H100 (¥78 vs ¥82) Faster queue time (3.2 vs 5.8 min)

QuQu AI

WeChat integration (China’s #1 chat app) TI Matrix (Tencent’s AI platform) Cheaper egress (¥0.3 vs ¥0.5 per GB) Tencent ecosystem (COS, CDW, TKE)

QuQu AI wins on egress cost, WeChat integration. For most startups: QuQu AI (cheaper egress, WeChat distribution). For enterprises: DingTalk SmartCompute (mature, faster queue). FAQ Q: Can I switch between them easily? A: No, vendor lock-in is significant. Plan for 1-year minim
