Runway Dev Collapses Video, Image, and Avatar AI Into One API

Runway Dev is the company's answer to a problem every engineering team building generative media products knows well: you need video from one vendor, images from another, audio from a third, and interactive avatars from somewhere else entirely. Today, Runway is collapsing that stack into a single platform.

One API to rule them all

Runway Dev gives developers first-party access to Runway's frontier models -- Gen-4.5, Aleph 2.0, and Act-Two -- alongside best-in-class third-party models such as Seedance, GPT Image 2, and ElevenLabs. The pitch is straightforward: swap between any of them by changing a single line of code, and track spend across every model from one billing dashboard.

Models, Workflows, Recipes, and Characters are all accessible through a single API, with full visibility into cost per model, per endpoint, per team -- and one invoice for everything. For teams that have been stitching together a dozen separate integrations, that alone is a significant operational simplification.

The four pillars

Runway Dev is organized around four capabilities, each targeting a different part of the enterprise media production pipeline:

• Models: New models are available on day zero, and Runway Dev is the only platform pairing proprietary frontier media models with infrastructure built specifically to serve media at scale.
• Recipes: Pre-built endpoints that package Runway's prompting and workflow expertise into a single API call, making it easier to generate polished outputs without needing to build, tune, or maintain the underlying workflow yourself. Popular ones include Ad Localization, Product Swap, Multi-Shot Video, and Marketing Stock Image.
• Workflows: Custom pipelines that combine multiple models, modalities, and tasks, triggerable via custom endpoints.
