Runway

FluffBuzz ships a bundled runway provider for hosted video generation.

Property	Value
Provider id	`runway`
Auth	`RUNWAYML_API_SECRET` (canonical) or `RUNWAY_API_KEY`
API	Runway task-based video generation (`GET /v1/tasks/{id}` polling)

Getting started

Set the API key

fluffbuzz onboard --auth-choice runway-api-key

Set Runway as the default video provider

fluffbuzz config set agents.defaults.videoGenerationModel.primary "runway/gen4.5"

Generate a video

Ask the agent to generate a video. Runway will be used automatically.

Supported modes

Mode	Model	Reference input
Text-to-video	`gen4.5` (default)	None
Image-to-video	`gen4.5`	1 local or remote image
Video-to-video	`gen4_aleph`	1 local or remote video

Local image and video references are supported via data URIs. Text-only runs currently expose 16:9 and 9:16 aspect ratios.

Video-to-video currently requires runway/gen4_aleph specifically.

Configuration

{
  agents: {
    defaults: {
      videoGenerationModel: {
        primary: "runway/gen4.5",
      },
    },
  },
}

Advanced configuration

Environment variable aliases

FluffBuzz recognizes both RUNWAYML_API_SECRET (canonical) and RUNWAY_API_KEY. Either variable will authenticate the Runway provider.

Task polling

Runway uses a task-based API. After submitting a generation request, FluffBuzz polls GET /v1/tasks/{id} until the video is ready. No additional configuration is needed for the polling behavior.

Video generation

Shared tool parameters, provider selection, and async behavior.
