Meet the new Chinese vibe coding app that's so popular, one of its tools crashed (www.businessinsider.com)

Ant Group’s new AI coding app LingGuang blew up immediately after launch, hitting 1 million downloads in four days and topping 2 million within a week — a pace the company says beat ChatGPT and Sora’s early milestones in China. The sudden popularity briefly knocked out LingGuang’s marquee “flash program” feature, which lets users generate personalized, interactive apps from plain-language prompts in about 30 seconds (examples include kid activity generators and car-cost calculators). The outage was short-lived, but made clear the strain mass demand can place on real‑time AI services. For the AI/ML community this release is notable both for product direction and operational lessons. LingGuang is pitched as a multimodal assistant capable of producing 3D models, interactive charts, animations and an “AGI camera” that analyzes and edits scenes in real time — signaling growing user appetite for natural‑language, low‑code app creation and real‑time multimodal inference. The crash highlights infrastructure challenges around scaling low‑latency, high‑concurrency model serving (autoscaling, quantization, caching, edge vs. cloud tradeoffs). Strategically, Ant’s push (alongside other moves like healthcare app AQ and humanoid robot R1) positions it as a serious competitor in the global AI race, especially in consumer-facing, multimodal assistants.
