OpenAI's flagship multimodal assistant powered by GPT-6 and GPT-5.6 for reasoning, coding, and deep research.
Automatically routes prompts or lets users select between Instant responses and Medium, High, or Extra High thinking depth across GPT-5.6 Luna, GPT-5.6 Sol, and flagship GPT-6 Pro/Astra models.
Asynchronous software engineering and task agents that clone repositories, run terminal tests in sandboxed environments, resolve complex bugs, and submit pull requests.
Browses dozens of primary web sources, academic papers, and connected workspace documents over several minutes to compile structured, citation-backed analytical reports.
Provides a split-screen editor for inline prose and code revisions alongside low-latency voice conversations with live screen and camera grounding.

An AI writing workspace that keeps the craft in focus
Ask the built-in assistant to critique a passage, brainstorm alternatives or rewrite something, without leaving the document.
Keyboard-driven AI shortcuts find the better word, expand a bullet into prose or generate a list of ideas in place.
Threaded comments navigated by shortcut plus saved versions, so you can try a different way of saying something without losing the original.
Share a link for one-click co-editing in real time, or send a read-only link so others can simply read the finished piece.
