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.

AI-moderated voice interviews with findings you can defend
Live, two-way voice conversations that follow your guide, decide in the moment whether to probe or move on, and carry context from each link.
Fire a short interview right after signup, drop-off, checkout abandonment, cancellation or another key moment, while the context is still fresh.
Every theme opens to the participants behind it, and findings are flagged as strong, weak, overstated or contradicted so thin evidence is called thin.
One guide runs across markets in over 50 languages and voices, so multi-market studies no longer need separate translators or interviewers.
