In today’s tech news roundup, major developments across artificial intelligence, cloud infrastructure, and consumer technology highlight how rapidly the industry is evolving.

OpenAI has signed a significant agreement to provide its AI models to US defence and government agencies through Amazon Web Services (AWS). This deal extends OpenAI’s reach into classified operations and strengthens its position in the government sector after rival Anthropic was labeled a supply chain risk.

Google is improving the mobile browsing experience by introducing a desktop-style bookmarks bar in Chrome for Android tablets and foldable devices. The feature allows users to quickly access saved websites directly below the address bar, making navigation faster and more efficient on larger screens.

OpenAI has also delayed its proposed “adult mode” feature for ChatGPT following internal concerns around safety, emotional dependency, and potential misuse by minors. The company is now focusing on improving safeguards and refining age-verification systems before release.

Meanwhile, Nvidia has unveiled NemoClaw, a new software stack designed to make AI agents safer for enterprise use. Built on the OpenClaw ecosystem, it introduces guardrails and privacy controls to ensure autonomous AI systems operate securely within business environments.

Perplexity has expanded its “Computer” feature to Android, enabling users to automate complex workflows such as research, coding, and presentations. The system runs in a secure cloud environment and uses multiple AI models to complete tasks efficiently across devices.

From AI in defence to smarter browsing and automation tools, these updates show how AI is becoming deeply integrated into both enterprise systems and everyday user experiences.
