The age of truly interactive video generation has arrived. Yan, a groundbreaking framework developed by the Yan Team at Tencent, represents a quantum leap forward in AI-powered content creation, delivering real-time 1080P/60FPS interactive video generation that rivals AAA game production quality. This isn't just another research demo—it's a comprehensive foundational system that could fundamentally reshape how we create, consume, and interact with video content.

About the Research Team

The Yan framework was developed by the dedicated Yan Team at Tencent, building upon their extensive experience with modern 3D game environments, particularly leveraging data from Yuan Meng Star (元梦之星), Tencent's popular 3D multiplayer game platform. This team brings together expertise in computer graphics, machine learning, game development, and interactive media to create what they describe as "a foundational framework for interactive video generation."

The Interactive Video Revolution

Interactive Generative Video (IGV) represents the next frontier in AI content creation, moving beyond static video generation to create dynamic, responsive visual experiences. Unlike traditional video generation that produces fixed content, IGV responds to user inputs in real-time, enabling personalized, adaptive storytelling and immersive experiences.

The Yan Team's research addresses what they identify as three core challenges that have remained unresolved in the field:

1. Real-time, high-fidelity visual experience - Achieving game-quality graphics at broadcast framerates while maintaining complex physics simulation
2. Generalizable, prompt-controllable generation - Creating content that responds to diverse text and visual inputs across different domains with strong cross-domain generalization
3. Dynamic interactive editing - Enabling on-the-fly content customization and real-time editing during interaction, supporting coarse-to-fine control

As the research team notes: "Existing methods struggle to simultaneously attain high visual fidelity, sustained temporal coherence, and rich interactivity. Moreover, generated content typically remains static post-creation, lacking real-time adaptability or user customization."

Yan's Three-Module Architecture

The Yan Team designed their framework around three integrated modules, each targeting specific aspects of interactive video generation. All modules are trained on a shared dataset collected from modern 3D game environments, ensuring consistency and leveraging rich interactive data.

1. AAA-Level Simulation: Real-Time Excellence (Yan-Sim)

The Yan-Sim module represents the team's solution for achieving unprecedented real-time performance. The research details how they leverage a highly-compressed, low-latency 3D-VAE coupled with a KV-cache-based shift-window denoising inference process. This technical innovation enables:

• 1080P/60FPS performance in real-time interactive scenarios
• Complex physics simulation with sustained temporal consistency
• Low-latency response to user interactions (critical for real-time applications)
• High compression ratios without visual quality degradation
• AAA-level visual fidelity matching modern game production standards

According to the research: "This supports real-time interactive content creation driven by both text and image prompts across diverse domains." The system maintains the visual fidelity and mechanical complexity expected from modern AAA games while operating entirely through AI generation.

2. Multi-Modal Generation: Cross-Domain Creativity (Yan-Gen)

The Yan-Gen module introduces what the team calls a hierarchical autoregressive captioning method that intelligently injects game-specific knowledge into open-domain video diffusion models (VDMs). The research emphasizes how this transforms traditional VDMs into frame-wise, action-controllable, real-time infinite interactive video generators. Key capabilities include:

• Text-to-interaction generation from natural language prompts with game-specific understanding
• Image-to-interaction synthesis from visual references across different art styles
• Cross-domain fusion that blends styles and mechanics from entirely different sources
• Frame-wise, action-controllable real-time generation with temporal consistency
• Auto-regressive post-training for sustained interaction sequences
• Self-forcing post-training for improved quality and coherence

3. Multi-Granularity Editing: Dynamic Content Control (Yan-Edit)

The Yan-Edit module represents perhaps the most innovative aspect of the framework. The research details how this module employs a hybrid architecture that explicitly disentangles interactive mechanics simulation from visual rendering. This architectural decision enables revolutionary capabilities:

• Real-time content modification during active interaction sessions
• Multi-granularity control from high-level scene changes to fine-grained detail editing
• Text-driven editing commands that modify content on-the-fly without breaking immersion
• Persistent consistency across all editing operations and transitions
• Structure editing for modifying scene layouts and object arrangements
• Style editing for changing visual aesthetics while maintaining interaction logic

The research emphasizes this breakthrough: "Users can dynamically modify prompts to edit subsequent generated content interactively." This creates an unprecedented level of creative control where content can be authored and modified in real-time during the experience itself.

Technical Innovations Deep Dive

The Yan Team's research introduces several groundbreaking technical innovations that enable their unprecedented performance. The paper provides extensive detail on these methodological advances:

Hierarchical Captioning for World and Local Context Modeling

The research introduces a sophisticated two-level captioning approach that fundamentally changes how interactive content understands context:

• Global Captioning: "Defining the Static World" - Establishes overarching world context, environmental rules, and persistent elements
• Local Captioning: "Grounding Dynamic Events" - Captures specific interactions, character actions, and temporal events within the established world

This hierarchical approach allows the system to maintain world consistency and physics rules while enabling rich, contextual interactions that feel natural and responsive.

KV-Cache-Based Shift-Window Denoising

The Yan Team developed a novel KV-cache-based shift-window denoising inference process that represents a significant advancement in real-time diffusion model optimization. This technique dramatically reduces computational overhead while maintaining quality, which the research identifies as crucial for achieving real-time performance at high resolutions like 1080P/60FPS.

Data Collection and Training Methodology

The research details their comprehensive data collection pipeline that gathered high-quality interactive video data from modern 3D game environments. The team leveraged Yuan Meng Star, providing them with:

• Rich interactive scenarios with complex physics and mechanics
• High-quality visual assets at AAA production standards
• Diverse gameplay interactions for training robust models
• Temporal consistency across extended play sessions

Hybrid Mechanics-Rendering Architecture

A key innovation detailed in the research is the explicit disentanglement of interactive mechanics simulation from visual rendering. This architectural decision enables independent optimization of both components:

• Interactive Mechanics Simulator: Handles physics, game logic, and interaction rules
• Visual Renderer: Focuses purely on high-quality image generation
• Modular editing capabilities that can modify either aspect independently
• Complex interactive mechanics without visual rendering computational overhead
• High-quality visual output without physics computation bottlenecks
