AI Round-up: March 25, 2026

Official platform and lab updates led the week, with OpenAI, Anthropic, and Microsoft carrying most of the news layer while X tilted toward launches and product momentum from GPT-5.4 mini, Perplexity Computer and Comet, Mistral Forge, and new Gemini features. The overall tone was practical rather than speculative: enterprise deployment, scientific research, digital sovereignty, and AI systems getting pushed deeper into real products and workflows.

The community layer was sharper and more argumentative. YouTube filled out around Claude, Gemini, Copilot, and OpenAI tutorials and demos, while Reddit centred on the Cursor Composer 2 and Moonshot/Kimi dispute, with smaller but active threads around Codex, Perplexity, and Claude Code.
