OpenAI Shuts Down Sora: End of AI Video Platform After Just Six Months
OpenAI has announced the discontinuation of its AI-powered video platform Sora, launched in December 2024 and released as a standalone app in September 2025. Despite an initial surge of over one million downloads within five days, Sora is being shut down due to high operational costs, declining user engagement, regulatory challenges, and a strategic shift toward more profitable ventures. Disney, which recently invested $1 billion in Sora, will retain its investment but will abandon joint projects. The app and web version will cease operations on April 26, 2026, with the API ending on September 24, 2026.
Microsoft Responds to Criticism: Windows 11 to Receive Major Improvements and AI Adjustments
Microsoft is responding to widespread criticism of Windows 11 with a major quality offensive by the end of 2026, including abandoning mandatory Microsoft account sign-ins, reducing AI integration, and introducing a movable taskbar. The company is also revising its Copilot strategy and halting automatic app installations due to user backlash. Meanwhile, Microsoft is considering legal action against OpenAI and Amazon over a cloud partnership that may violate an exclusivity agreement.
OpenAI has unveiled the new AI model GPT-5.4, which integrates native computer control, programming, and complex logical reasoning into a single system. The model outperforms competitors such as Anthropic Opus 4.6 in desktop control and achieves high scores in benchmarks like OSWorld-Verified and GDPval. With a context window of up to one million tokens and dynamic tool search, it reduces token usage and lowers costs. Meanwhile, Anthropic is challenging the U.S. Pentagon’s supply chain risk designation, while Nintendo has sued the U.S. government over tariffs on Switch consoles.
Amazon and OpenAI have announced a strategic partnership worth over $150 billion, involving investments, the use of Trainium chips, and custom AI model development. OpenAI has also signed an agreement with the U.S. Pentagon to deploy its AI models in classified networks, while implementing safeguards against mass surveillance. Meanwhile, Anthropic is advancing AI capabilities with its free Memory feature for Claude and the discovery of 22 security vulnerabilities in Firefox using its Claude Opus 4.6 model. In parallel, OpenAI has postponed the launch of ChatGPT's adult mode, and performance issues with the GeForce RTX 4090 in Resident Evil Requiem have been resolved.
The Trump administration has banned the U.S. military from using AI models from Anthropic, classifying the company as a supply chain risk. OpenAI capitalized on the gap by securing a Pentagon contract for handling sensitive data, sparking criticism over mass surveillance and autonomous weapons. Meanwhile, Caitlin Kalinowski, head of OpenAI’s robotics division, resigned after criticizing the company’s military ties. In a separate incident, a Mexican startup incurred over $82,000 in cloud costs within two days due to a stolen Google Cloud API key, highlighting critical security vulnerabilities.
AI company Anthropic is facing intense pressure after the Pentagon classified it as a supply chain risk and demanded the removal of security filters for military use. The company has filed a lawsuit against the U.S. government, arguing the designation is legally invalid and threatens its business. Meanwhile, competitors like OpenAI have secured military contracts, while studies reveal that most firms have not seen measurable productivity gains from AI despite heavy investments. The conflict highlights growing tensions between AI safety, national security, and economic implications.
