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.

Repeatable browser QA for teams that ship with coding agents
Connect your own AI coding agent over MCP and let it investigate the app, write Playwright actions, locators, and assertions, then validate the test through Toolbar before saving.
Validated tests and shared helpers are stored with full version history, so you can trace which test version actually failed and refine coverage over time.
Execute tests on demand, on a recurring schedule, when a Vercel preview is ready, or after merged changes reach a deployment.
Open any failed run to review recorded steps, screenshots, and Playwright traces, then hand that evidence to your agent for root-cause investigation.
