Overview

What DreamX-World-5B does

DreamX-World is a general-purpose interactive world model from Alibaba's AMAP research team. DreamX-World-5B, built on a Wan2.2-TI2V backbone, is served on Windflow as a portrait-format controllable world rollout driven by a seed image, a text prompt and movement and camera-control state.

A session keeps the model running: connect once, steer it with text prompts, a reference image and movement and look controls while it runs, and receive the live stream back on a named output track.

Every model in the catalog speaks the same typed session protocol, so switching between models changes the controls you send, not how you integrate.

FAQ

Questions about DreamX-World-5B

What orientation does DreamX-World-5B produce?
Portrait, at 704 × 1280 in the production runtime; the exact size is negotiated per session.
How do controls reach the model?
Movement and camera state are sampled into the next action sequence, so a control change takes effect at the next rollout rather than on the very next frame.
How much does DreamX-World-5B cost on Windflow?
DreamX-World-5B costs $0.0023 per billable session-second ($8.28/hr of billable time). Billing starts at the session's first generation_started event and stops when the session is released or ends. Queueing, worker startup, time before generation starts and the documented reconnect grace are not billed. After generation starts, paused or unwatched time remains billable; release the owner session to stop the meter. There is no subscription.
How do I get access to DreamX-World-5B?
Windflow is in private beta. Request access from the sign-up page, or ask for a live demo of DreamX-World-5B. Approved accounts start with $5 and four concurrent sessions.
Is DreamX-World-5B always running?
No. Model capacity is brought up on demand rather than kept standing. Live readiness for each model is published at api.windflow.online/v1/status, and a live demo can be arranged on request.
