Alibaba maps a 20GW full-stack AI buildout

Alibaba says its full-stack AI roadmap will take its cloud data-center capacity past 20GW by 2032. The Apsara Conference roadmap also puts Qwen 4 in training, targets 5–10 trillion parameters for Qwen 4.5 and Qwen 5, and says the Zhenwu V900 is three times faster than its predecessor with 216GB of GPU memory; mass production is scheduled for Q1 2027. Builders should treat this as a capacity-and-platform signal rather than a model benchmark: Alibaba is tying open-model scale, proprietary silicon, and cloud supply into one stack, which sharpens the case for tracking open-weight model ecosystems.
