LingBot-World 2.0 vs DreamX-World-5B: inputs, controls and API cost
Compare LingBot-World 2.0 and DreamX-World-5B APIs: inputs, outputs, streaming delivery and ready-second cost. Choose a Windflow model for your product.
LingBot-World 2.0 and DreamX-World-5B are both navigable world model options in Windflow's public catalog. Choose by the inputs and interaction you need, then evaluate quality and responsiveness with your actual application. This page compares the published serving profiles; it does not present a head-to-head performance experiment.

Specifications side by side
| Published specification | LingBot-World 2.0 | DreamX-World-5B |
|---|---|---|
| Architecture | Seed-image conditioned navigable world model | 5B controllable world generation model (Wan2.2-TI2V backbone) |
| Resolution | 1408 × 768 delivery (704 × 384 generation) | 704 × 1280 portrait in the production runtime; negotiated per session |
| Chunk | Movement and look apply at the next generation-block boundary | Action-sequence conditioned rollout |
| Inputs | A seed image (uploadFile) and a text prompt, plus persistent WASD movement and look controls | A seed image, a text prompt, and movement/camera-control state |
| Outputs | A navigable stream on main_video you steer in real time | A controllable world rollout on main_video |
| Delivery | WebSocket (H.264) · WebRTC | WebSocket (H.264) · WebRTC |
| Session protocol | sdk.realtime.v2 | sdk.realtime.v2 |
| Price | $0.0024 per ready second | $0.0023 per ready second |
| Implementation status | production | production |
Implementation status describes runtime maturity. Live GPU readiness is reported separately; Windflow is in private beta and brings capacity up on demand.
Input and control fit
Both models accept text prompts in the published Windflow profile. Both models accept reference or seed images in the published Windflow profile. Both models do not accept uploaded source clips in the published Windflow profile. Both models do not accept live webcam input in the published Windflow profile. Both models accept movement and look controls in the published Windflow profile.
A shared session API does not make commands interchangeable. Use each model's supported inputs and control timing. In particular, prompt changes may land at a chunk or generation-window boundary; movement input can represent persistent state until replaced.
What LingBot-World 2.0 is designed for
LingBot-World is an open-source world model from Robbyant, Ant Group's embodied-intelligence unit. On Windflow, LingBot-World 2.0 turns a seed image and a text prompt into a navigable stream that you steer in real time with persistent WASD movement and look controls.
- Navigable game-like worlds generated from a single image.
- Interactive scene exploration for previsualisation and level concepting.
- Embodied-AI and simulation research that needs a controllable world stream.
- Prototyping WASD-controlled experiences without building a game engine first.
What DreamX-World-5B is designed for
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.
- Portrait-format interactive worlds for mobile-first experiences.
- Prompt-and-action controlled scene rollouts from a single image.
- Short controllable scenes for storyboarding and previsualisation.
- Evaluating a 5B world model against larger alternatives.
Compare a realistic session budget
- LingBot-World 2.0: $0.0024 per ready second, or $1.44 for ten ready minutes.
- DreamX-World-5B: $0.0023 per ready second, or $1.38 for ten ready minutes.
Queueing and worker startup are free. A ready owner session can remain billable while delivery is paused or unwatched; release it when done. Independent sessions carry independent meters. Use the cost calculator to estimate your duration and daily sessions.
Evaluate before choosing
Use one repeatable input sequence, the same client and network, and equivalent output expectations. Record first visible frame, control-to-visible delay, frame gaps, scene continuity and rejected controls. Run several starts and a sustained session. If serving profiles differ, label the differences instead of treating displayed FPS as directly comparable native generation speed.
See the latency measurement guide and the model selector for a reproducible decision process.

FAQ
Is LingBot-World 2.0 better than DreamX-World-5B?
The answer depends on the inputs, control behavior, quality and output your product requires. The published specifications identify capability differences; an application-level evaluation establishes performance for your scenario.
Can I switch between these models through the same API?
Windflow keeps the session lifecycle common. Your application must adapt to each model's supported inputs, commands, output tracks and generation timing.
Do the published prices guarantee available GPU capacity?
No. Rates and implementation status are catalog facts. Live readiness is a separate operational signal, and private-beta access is required to run sessions.
