The Model API Reference is the source of truth for what each model accepts and emits: every command, every parameter, every event. This is distinct from the SDK Reference, which documents the JavaScript and Python client libraries (sessions, connect/disconnect, file uploads, raw event sending). Learning how to use Reactor is one thing; learning how to drive a specific model is another. For background on what a Reactor model is, see What is a Reactor model?.
For the initial release, each model’s reference is hand-written here. Longer term, these pages will be generated automatically from each model’s published schema so they stay in lockstep with what’s deployed.

​
Available models

Helios

Interactive real-time video generation with autoregressive chunked diffusion and image-to-video support.

LingBot

Real-time navigable video model with WASD movement, look controls, and live prompt steering.

LingBot World 2

Image-anchored navigable world model with two-axis WASD driving, directed camera moves, and live prompt steering.

LongLive-2.0

Autoregressive multi-shot video generation: direct a sequence with soft shots and hard cuts, live or scheduled.

SANA-Streaming

Real-time streaming video editing: surgical text-driven edits to uploaded clips or a live webcam feed.
Each per-model page combines the overview, schema, prompt guide, and tutorial in a single document.

​
What you’ll find per model

  • Every command the model accepts, with parameter types and constraints
  • Every event the model emits, with payload shapes
  • Track capabilities (which media streams are publishable or receivable)
  • Any model-specific preconditions or ordering rules

​
Working without a typed SDK

If a model doesn’t have a typed SDK published yet, or you’re prototyping against a model in development, drive it from the base Reactor class using sendCommand() and raw event payloads. The Model API Reference tells you exactly what those payloads should look like.
