Performance

Real-time isn't a claim. It's a number.

Characters respond in seconds and stream video at 24fps, so conversations feel live — not generated. Fast enough for back-and-forth coaching, support and other interactive experiences.

37ms

Effective model time per frame, fast enough to keep Characters moving at 24fps.

1.75s

Server-side turnaround from when you stop speaking to when the character starts responding.

Expressive generation across any visual style. Below are 720p clips showing Characters animating a single reference image across styles—from photorealistic humans to cartoons, creatures and brand mascots—with natural, expressive conversation.

Product Features

From model to product ecosystem.

Real-time video is only part of the system. Ground characters in your domain, connect them to apps and deploy them where conversations happen.

Camera & screen sharing

Vision

Characters can see your webcam or shared screen during a session for tutoring, demos, games and design feedback.

Text-to-voice & cloning

Custom voice

Design a voice from a prompt or clone instantly from a sample, then assign it for consistent tone across every session.

Grounded responses

Knowledge base

Ground characters by attaching your own docs so they answer with real knowledge of your company, products and policies.

Zoom, Meet and Teams

Meeting integration

Bring characters into real meetings so they see and hear the room and respond in real time, from standups to customer calls.

For Developers

Integrate real-time avatars into your app.

Add Characters to the stack you already use: connect through LiveKit Agents, build custom interfaces with the React SDK or drop a hosted widget into your site with a single script tag.

Customer Proof

Powering real work in production.

“The Runway team was great to work with. They helped us iterate on the look, the feel, the response mechanism and the knowledge base quickly. My personal view, when it was done: I was impressed it worked so well in that short space of time.”
Andy Corp, Head of Product at BBC Studios

Frequently asked questions

How does Characters pricing work?
Characters uses Runway API credits. Characters cost 2 credits upfront, then 2 credits per 6 seconds of active session time. Credits are purchased in the Developer Portal. One credit is $0.01 before any applicable taxes. See the pricing docs for more details.
How many characters can I create?
You can create as many Characters as you want. Creating a Character does not start billing by itself; credits are charged when you start a realtime call session with that Character.
Can I use Characters with LiveKit?
Yes. Runway provides a LiveKit Agents integration for fully custom conversational experiences. Your LiveKit agent can handle speech-to-text, the language model and text-to-speech, while Runway provides the visual layer: audio in, avatar video out.
What is the fastest way to add a Character to my site?
Use the embedded widget. It adds a Character with a single script tag, does not require a backend and is configured in the Developer Portal. For custom app experiences with full control over the UI and session lifecycle, use the React SDK instead.
What can I customize?
Characters can be generated from a single image and configured with voice, personality, knowledge and actions. You can use photorealistic or animated styles, human or non-human characters, custom voices, knowledge bases and tools that let a Character trigger UI changes or call trusted backend services.
How real-time is it?
Characters generates expressive video at 24fps in HD, with fast turn-taking designed for live conversation. Learn more in the Building Runway Characters technical breakdown.
