OpenAI released GPT-5.5, positioning it as a major step toward a unified AI "super app" combining ChatGPT, coding tools, and browser capabilities. The model delivers improved reasoning and speed for enterprise and scientific tasks.

OpenAI also launched workspace agents in ChatGPT for Business and Enterprise users, enabling teams to build and share AI agents that autonomously complete tasks across Slack, Gmail, and other tools. These agents gather context, follow workflows, and request approvals—representing a shift from AI that assists to AI that does work.

Microsoft introduced Agent Mode across Word, Excel, and PowerPoint, allowing AI to directly execute multi-step tasks while showing each step in real time. Users can now automate editing, data updates, and formatting without manual intervention.

Google expanded Workspace with AI-driven capabilities through Workspace Intelligence, enabling Gemini to build spreadsheets, organize unstructured data, and refine written content.

DeepSeek released preview versions of its V4 AI model with significantly expanded context windows and improved efficiency in agentic workflows.

The US unveiled measures Thursday to prevent Chinese developers from improperly using leading US AI models to build competing chatbots.

These updates signal the industry's pivot toward autonomous AI agents as the core productivity layer.
