Model overview
> We present **MultiTalk**, an open-source audio-driven multi-person conversational video generation model with the state-of-the-art lip synchronization accuracy. > Key features: > - 💬 Realistic Conversations - Supports single & multi-person generation > - 👥 Interactive Character Control - Direct virtual humans via prompts > - 🎤 Generalization Performances - Supports the generation of cartoon character and singing > - 📺 Resolution Flexibility: 480p & 720p output at arbitrary aspect ratios > - ⏱️ **Long Video Generation**: Support video generation up to 15 seconds This repository hosts the model weights for **MultiTalk**. For installation, usage instructions, and further documentation, please visit our GitHub repository. We propose a novel framework, MultiTalk, for audio-driven multi-person conversational video generation. We investigate several schemes for audio injection and introduce the Label Rotary Position Embedding (L-RoPE) method. By assigning identical labels to audio embeddings and video latents, it effectively activates specific regions within the audio cross-attention map, thereby resolving incorrect binding issues. To localize the region of the specified person, we introduce the adaptive person localization by computing the similarity between the features of the given region of a person in the reference image and all the features of the whole video.

Limitations & considerations
Sources are insufficient to establish specific limitations. Verify task performance, latency, data policies, licensing and version lifecycle.
Source prices & cost analysis
Prices vary by channel, region and configuration. Channel quotes are listed independently and are not treated as a single official provider price.

Do open weights permit free commercial use?
Not necessarily. Check the version license, commercial conditions and usage policies. Self-hosting incurs compute and maintenance costs.
Are these real-time billing prices?
These are timestamped source snapshots, not live billing prices. Check the channel for current versions, regions, discounts and billing methods.
