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.
Talk to your coding agents and hear them talk back
Talk to your agents and hear spoken replies in real time, so you can ask for a change, hear the result and answer the follow-up without returning to the keyboard.
SKI keeps project, branch and chat context across every project, and hands each job to the right agent when you ask where things stand.
Each chat gets its own branch and worktree so parallel agents never collide; watch live diffs and open a pull request by voice.
Run Claude Code, Codex, Antigravity, OpenCode and others simultaneously, each on its own task, with a notification the moment one needs you.
Provides massive context windows and deep Google Workspace integration, but trails behind in advanced coding workflows.
