OpenAI announced on 25 March that it will shut down its Sora AI video generation app roughly one year after its public launch, with the consumer app closing on 26 April and the API following on 24 September. The company offered no detailed explanation beyond acknowledging the news was "disappointing," though it stressed it is not abandoning AI video research entirely. The closure also kills a three-year, billion-dollar licensing agreement with Disney, which had planned to integrate Sora into Disney+ and take a US$1 billion stake in the company. App downloads had been in freefall, dropping 32 per cent month-over-month in December 2025 and a further 45 per cent in January 2026, while brand campaigns using the tool from the likes of Toys R Us and Coca-Cola drew audience backlash over output quality.

Vietnam's FPT Corporation announced on 26 March that its AI Factory division will integrate NVIDIA's HGX B300 systems into its production-grade AI Developer Cloud, giving enterprises and researchers across Southeast Asia and Japan access to next-generation reasoning and agentic AI capabilities. The platform already serves more than 18,000 engineers, scientists, and business users through 43 cloud services, with existing HGX H100 and H200 infrastructure delivering what FPT describes as multi-fold performance gains in both training and inference workloads. NVIDIA HGX B300 early access registrations are now open, though a firm availability date has not been confirmed.
