## DreamX-World-5B

- API: https://windflow.online/models/dreamx-world-5b
- Implementation: production; live readiness is reported separately.
- Architecture: 5B controllable world generation model (Wan2.2-TI2V backbone)
- Resolution: 704 × 1280 portrait in the production runtime; negotiated per session
- Chunk: Action-sequence conditioned rollout
- Inputs: A seed image, a text prompt, and movement/camera-control state

- Delivery: WebSocket (H.264) · WebRTC
- Session protocol: sdk.realtime.v2
- Price: $0.0023 per ready second

## ABot-World-0-5B

- API: https://windflow.online/models/abot-world-0-5b
- Implementation: production; live readiness is reported separately.
- Architecture: 5B keyboard-conditioned world model (Wan2.2-TI2V backbone, LongForcing causal student)
- Resolution: 1344 × 768 delivered (896 × 512 generation + learned super-resolution)
- Chunk: 12-frame AR blocks; held keys are sampled at each block boundary
- Inputs: A seed image, a text prompt, and persistent movement/camera key state

## MiniMax FastH3

- API: https://windflow.online/models/fast-h3
- Implementation: production; live readiness is reported separately.
- Architecture: 35B MiniMax H3 text-to-video-and-audio model, DMD2-distilled to four DiT calls with 90% sparse VSA-H3 attention
- Resolution: 960 × 544
- Playout: 24
- Chunk: 345 frames per window (14.38 s at 24 fps; published as the 15 s profile)
- Control latency: A whole window. The pipeline materialises the clip before delivery, so time-to-first-frame equals one generation.
- Inputs: A text prompt with visual, dialogue, soundscape, and music direction
- Outputs: Video on main_video and generated audio downmixed to mono on main_audio, aligned per window
- Delivery: WebRTC
- Session protocol: sdk.realtime.v2
- Price: $0.0069 per ready second

## LTX-2.5

- API: https://windflow.online/models/ltx-2-5
- Implementation: production; live readiness is reported separately.
- Architecture: 22B joint audio+video DiT, two-stage, generated one window at a time
- Resolution: 832 × 448 measured; the canvas is configurable in multiples of 64
- Playout: 24
- Chunk: 241 frames per window (10.04 s)
- Control latency: A whole window: the pipeline does not yield progressively, so time-to-first-frame equals one window's generation time. The reference still is published while it runs.
- Inputs: A text prompt and an optional reference still
- Outputs: Video on main_video and the audio generated with it on main_audio, aligned per window
- Delivery: WebRTC
- Session protocol: sdk.realtime.v2
- Price: $0.0040 per ready second
