Overview
- OpenAI launched the GPT‑5.6 model family and a new agent called ChatGPT Work on July 9, 2026, moving ChatGPT from a chat tool to a platform that can run multi‑step tasks across web, desktop and mobile.
- GPT‑5.6 comes in three variants—Sol (flagship for heavy reasoning), Terra (balanced for everyday work) and Luna (fast and low‑cost)—so customers can choose tradeoffs between speed, capability and price.
- ChatGPT Work can access local files and apps, use a built‑in browser and plugins, run scheduled background tasks, and coordinate sub‑agents in an 'Ultra' mode to produce finished deliverables like spreadsheets, slides and websites.
- OpenAI began a phased rollout that gives paid tiers earlier access and followed a restricted preview after a U.S. government cybersecurity review; the company says it briefed officials and made changes during that review.
- OpenAI published per‑token pricing and efficiency claims—for example, Sol is priced higher than Terra and Luna and is promoted as more token‑efficient—which raises questions about costs for high‑volume agent workflows and two‑tier access for users.
