This Monday morning, OpenAI has launched GPT-5.6, confirmed by both bluewin.ch and UC Today, introducing new performance classes: Sol for demanding tasks, Terra for everyday use, and Luna for fast, affordable options. Free and Go plan users get Terra by default, while paying customers can switch between all three.

OpenAI is also heavily pushing its new productivity tool, "ChatGPT Work," which integrates directly into connected apps and files to create documents, spreadsheets, or presentations.
