In early June 2026, Runway released its latest General World Model, GWM-1. Alongside it came the Characters feature—powered by GWM-1. Characters lets you create real-time conversational video agents with custom voices, knowledge bases, and personalities, all from a single image. This marks a major shift in AI video creation: from "static content generation" to "dynamic interactive experiences."
For content creators, developers, and enterprise users, GWM-1 and Characters unlock unprecedented capabilities. Upload just one reference image, and within minutes you can deploy a digital character capable of real-time video conversations. Response times drop to as low as 37 milliseconds per frame, supporting smooth 24fps video streams. In this article, we'll dive deep into GWM-1's technical architecture, provide a complete walkthrough for using Characters, and compare it in detail against the previous Gen-4.5.
Why GWM-1 Is the Next Milestone in Video Generation
From Gen-4.5 to GWM-1: Understanding the Architecture Upgrade
Runway's Gen-4.5 already demonstrated powerful image-to-video capabilities. But at its core, it remained a "one-way generation" model. You input a prompt or reference image, and the model outputs a pre-rendered video clip. GWM-1 represents an entirely new paradigm. It's a General World Model that understands and simulates the dynamic laws of the physical world, enabling real-time interaction.
The breakthrough behind GWM-1 lies in its architectural design. Instead of focusing solely on pixel-level video synthesis, it builds a world simulator capable of understanding causality, temporal continuity, and spatial consistency. This allows GWM-1 to dynamically generate logically coherent video responses upon receiving real-time inputs—such as user voice or text commands—rather than simply replaying pre-generated content.
From a technical standpoint, GWM-1 achieves three key metrics: - Effective model time per frame: 37ms — The model processes each video frame in an extremely short time, sufficient for real-time interaction. - Server-side turnaround time: 1.75s — Total latency from receiving input to returning a response stays under 2 seconds, which is smooth enough for video conversations. - Supports 24fps video streaming — Output video reaches cinema-grade frame rates, ensuring visual coherence.
These performance indicators transform GWM-1 from a traditional "video generation tool" into a true "real-time video agent platform."
Characters: From Static Images to Real-Time Conversational Roles
Characters is GWM-1's first consumer-facing application. Its core concept is straightforward: start with a single image and create a digital character capable of real-time video conversations.
Traditionally, creating a digital character with a specific appearance and behavior required complex 3D modeling, rigging, animation production, and voice synthesis—taking weeks or even months. Characters compresses this entire process into minutes:
- Upload a reference image — It can be a photo, an illustration, or even an AI-generated image.
- Configure character attributes — Choose a voice, set a personality, and import a knowledge base.
- Deploy the character — Integrate the character into web apps or mobile applications via API or embed code.
The entire process requires zero fine-tuning. This means even users without a machine learning background can get started easily. More importantly, characters generated by Characters not only closely match the reference image in appearance but also adapt their expressions and movements based on conversation content, achieving truly "expressive digital personas."
Complete Runway Characters Tutorial
Step 1: Access Runway and Select Characters
First, visit the Runway official website and log in to your account. If you don't have an account yet, sign up for a free trial. After logging in, find the "Products" menu in the main navigation bar and click "Characters" to enter the product page. You can also go directly to the Characters product page to learn more about its features.
On the Characters page, you'll see several core modules: - Create Character — Create a new character - My Characters — Manage your created characters - Deployments — View deployment status and integration options for your characters
Click "Create Character" to start building your first digital character.
Step 2: Upload a Reference Image and Generate the Character
In the character creation interface, the first step is uploading a reference image. Supported formats include JPG, PNG, and WebP. We recommend a resolution of at least 512x512 pixels to ensure clear details in the generated character.
After uploading, GWM-1 automatically analyzes the person's features in the image, including facial structure, hairstyle, and clothing style. You'll see a preliminary character model in the preview window. If you're not satisfied with the result, try these optimization tips:
- Use clear, front-facing photos — Avoid side profiles, obstructions, or blurry images.
- Ensure even lighting — Overly bright or dark lighting can affect facial feature recognition.
- Choose a representative image — If you want the character to maintain a certain emotional tone during conversations, pick a reference image with a matching expression.
Once you're happy with the image, click "Next" to move to the character configuration stage.
Step 3: Configure Voice, Personality, and Knowledge
What makes Characters powerful is its high degree of customization. In this step, you can set the following attributes for your character:
Voice Configuration: - Choose from a preset voice library covering multiple languages, ages, and timbres. - Or upload your own audio samples for voice cloning (requires additional authorization). - Adjust speech speed, pitch, and emotional倾向.
Personality Settings: - Select from preset personality templates such as "Friendly Assistant," "Professional Advisor," or "Humorous Companion." - Or describe your desired personality traits in natural language, e.g., "enthusiastic but not excessive, professional but not cold." - The system automatically adjusts the character's language style and response patterns based on your description.
Knowledge Base Import: - Upload documents, PDFs, or webpage links to give the character domain-specific knowledge. - This is especially useful for creating customer service bots, educational tutors, or professional training roles. - The knowledge base is retrieved in real time during conversations, ensuring accurate and relevant responses.
After completing the configuration, enter test mode. Have a simple text or voice conversation with the character to verify that its behavior meets your expectations.
Step 4: Deploy to Web or App
Once you're satisfied with the character's performance, you can deploy it to real-world scenarios. Runway offers several deployment options:
Web Embedding: - Get a JavaScript embed code and insert it directly into your website. - Customize the chat window's style and position. - Ideal for online customer service, virtual assistants, and similar use cases.
API Integration: - Integrate the character into mobile apps, desktop software, or third-party platforms via a RESTful API. - The API supports both text input/output and voice input/output modes. - Detailed API documentation is available on the Runway Developer Portal.
Real-Time Video Streaming: - For scenarios requiring video output, use the real-time video streaming interface. - Supports WebSocket connections for low-latency, bidirectional communication. - Suitable for virtual streamers, online teaching, remote meetings, and other applications.
After deployment, monitor your character's usage in the "Deployments" panel. Track metrics like conversation count, user satisfaction feedback, and performance indicators.
