Realtime video generation
LTX-2.5
Video on main_video and the audio generated with it on main_audio, aligned per window. Served on Windflow as a realtime session you can plug into your product and pay for by the second.
Overview
What LTX-2.5 does
LTX-2.5 is a 22B joint audio+video DiT, two-stage, generated one window at a time. On Windflow it runs as a realtime session: connect once, steer it with text prompts and a reference image 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.
- Architecture

- 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.
