The week in brief
Week 10/2026 is defined by leaps in performance and new approaches: GPT-5.4 sets new standards for professional workflows with its "thinking" architecture and scores 83% on GDPval, ahead of all predecessors. Variant changes the design process with an endless, scrollable feed of UI designs: no empty canvas, no prompt engineering. Parsewise brings Cursor-like intelligence to documents and addresses the large market of insurance and finance. Heywa replaces the wall of text in ChatGPT with interactive, visual stories, a shift in research UX. Luma Agents shows that a complete advertising campaign worth 15 million dollars can be produced in 40 hours for 20,000 dollars.
