In the JavaScript SDK pages read, input is a text prompt plus an optional start image (25 MB cap, resized to 1280x704 or 704x1280) and further text "interact" prompts; scripted simulations add timestamps. No keyboard, gamepad or camera-pose action type appears in those pages. Outputs are a WebRTC video stream, optional broadcast to spectators, and per-stream recordings (MP4, JSONL event log, JPEG thumbnail, preview MP4). A default prompt-expansion step is documented.
