| </p> | |
| <ul style="list-style-type: disc; padding-left: 20px;"> | |
| <li><strong>Streaming Multimodal Reference Generation:</strong> By extending diffusion forcing from chunkwise generation to streaming multimodal references, FlowAct-R2 enables real-time video generation with rolling prompts and multimodal references, including continuously updated images, audio, and video, and supports hour‑level ultra‑long video generation with 720p. </li> | |
| <li><strong>Proactive Interaction Agent:</strong> | |
| To enable digital humans to autonomously drive their behavior when no external input is present, while seamlessly responding when interactions arise, FlowAct-R2 introduce an agent workflow with pre-online planning and online scheduling and response, which supports persona-driven behaviors, interruption handling, and skill execution for autonomous live interactions.</li> | |
| <li><strong>Rich Behaviors Across Diverse Live Scenarios:</strong> FlowAct-R2 supports real-time text and audio interactions across four representative scenarios—video chatting, live shopping, entertainment streaming, and interactive gaming—generating not only conversational responses but also expressive behaviors and task-oriented actions beyond conventional question answering.</li> | |

| Overview of <span class="dnerf">FlowAct-R2</span>. | |
| FlowAct-R2 enables proactive, lifelike humanoid video generation by coupling a two-stage proactive agent with a streaming multi-reference DiT. The agent pre-plans long-horizon agendas and reusable multimodal skills offline, and dynamically orchestrates online responses, tool execution, and real-time interruptions. Conditioned on rolling action prompts and streaming audio, the generative backbone incorporates video-driven RoPE and an explicitly trained (R+I)2V multi-reference mechanism—supporting dynamic image, audio, and video references to suppress cumulative drift and synthesize high-fidelity 720p avatar videos in real time. | |
| </p> | |
| <h3 class="title is-5" style="margin-top: 1.5rem;">Streaming Multimoal Reference DiT</h3> | |
| <p class="subtitle"> | |
| Existing streaming video generation methods are typically adapted from image-to-video (I2V) or text-to-video (T2V) models, limiting their ability to incorporate dynamically evolving references and often requiring substantial architectural modifications for long-horizon consistency. However, interactive digital humans demand continuous multimodal control across diverse scenarios, such as e-commerce livestreaming, talent performances, and scene exploration. | |
| </p> | |
| <p class="subtitle"> | |
| We present FlowAct-R2, a streaming adaptation of Seedance 2.0 Mini designed for interactive digital humans. Rather than augmenting an I2V model with attention sinks, FlowAct-R2 builds directly on a pre-trained reference-to-video (R2V) backbone, inheriting its strong reference preservation capability. We employ Diffusion Forcing to enable autoregressive streaming inference while preserving the backbone and its bidirectional spatiotemporal attention. We further extend Diffusion Forcing to streaming multimodal reference generation, allowing image, audio, and video references, together with text prompts, to be continuously updated or switched during inference. A modified RoPE aligns incoming reference chunks with the corresponding generation timeline, ensuring temporally synchronized control. | |
| </p> | |
| <p class="subtitle"> | |
| The strong reference conditioning of the R2V backbone already substantially reduces autoregressive drift by continuously anchoring generation to the reference content. To further suppress residual error accumulation, we condition the model on partially noised historical motion frames rather than clean ones, improving its robustness to imperfect generated histories. Specialized audio-driven training enhances synchronization among speech, lip movements, expressions, and head poses, while coarse-to-fine inference progressively restores visual details. Together, these designs enable stable, hour-long, real-time 720p digital human generation under continuous multimodal control. | |
| </p> | |
| <h3 class="title is-5" style="margin-top: 1.5rem;">Proactive Interaction Agent</h3> | |
| <p class="subtitle"> | |
| Proactivity in a streaming digital human extends beyond generating timely responses to user inputs: the digital human must continuously determine what to do next, even in the absence of explicit instructions, while maintaining a coherent persona and pursuing the long-term objectives of the live session. This creates a fundamental tension between long-horizon preparation and online adaptation. Purely online planning is often too myopic and latency-sensitive to organize an entire session or synthesize complex behaviors on demand, whereas a fixed offline script cannot accommodate unpredictable audience interactions or evolving contexts. | |
| </p> | |
| <p class="subtitle"> | |
| FlowAct-R2 therefore adopts a two-stage agent architecture. Offline, it derives a persona from multimodal character assets, organizes the session into a long-horizon agenda, and compiles complex behaviors into reusable skills. Online, a scheduling agent integrates the agenda, interaction events, and historical context to determine when to initiate, overlay, defer, interrupt, or resume behaviors, while invoking the appropriate skills for execution. This design enables the digital human to autonomously sustain the live session while remaining responsive to interactions. | |

| Compared with Vidu-S2, FlowAct-R2 better preserves the appearance of referenced objects and switches more naturally between product references, demonstrating stronger object consistency and reference switching in these live shopping examples. Both Vidu-S2 and FlowAct-R2 can trigger dance from text; FlowAct-R2 further supports reference-video conditioning, enabling more expressive dance generation. | |
