LongCat-Video-Avatar 1.5

LongCat-Video-Avatar 1.5 is a Meituan LongCat model for audio-driven avatar video generation.

The Hugging Face model card presents it around audio-text-to-video, audio-image-text-to-video, and video-continuation workflows, with single- and multi-person audio modes, model weights, GitHub quickstart commands, usage tips, and project-reported evaluation materials. This page is a starting point, not a recommendation. Check the original source before relying on the resource.

What it is

An audio-driven avatar video model

LongCat-Video-Avatar 1.5 focuses on generating avatar-style video from audio, text, and optional image inputs rather than general prompt-to-video generation alone.

Why it stands out

Single- and multi-person avatar paths

The project materials describe single-person animation, multi-person animation, audio-text-to-video, audio-image-to-video, and video-continuation examples for longer avatar-style outputs.

Availability

Model card, weights, repo, and report

Readers can inspect the Hugging Face model card, model files, LongCat-Video repository setup, quick inference commands, usage tips, and linked technical report materials.

Why it matters

Why readers may notice it

Avatar video generation is one of the more visible parts of generative media. LongCat-Video-Avatar 1.5 is useful to track because it brings audio, identity consistency, multi-person scenes, and longer video continuation into one inspectable model release.

Reporting note

What appears notable

Based on the model card, readers may want to notice the Whisper-Large audio encoder update, single- and multi-character paths, INT8 option, distillation mode, 480p and 720p support, video-continuation examples, and project-reported human-evaluation materials.

Before using

What readers may want to review

The LongCat-Video repository setup, including CUDA, PyTorch, FlashAttention, ffmpeg, model downloads, and multi-GPU example commands.

The project's usage notes, especially around consent, identity, and likeness when working with real people's images, voices, or videos.

The project-reported evaluation setup and output examples before treating quality, stability, or lip-sync claims as general results.

Best fit

Who may find it relevant

Readers comparing avatar video generation, lip-sync systems, virtual presenters, or audio-driven character animation.

Creators and builders who want to inspect model weights and a technical setup path rather than only a hosted demo.

Less relevant for readers looking for a general chatbot, coding agent, or no-setup consumer video editor.

Editorial note

Why it is included here

LongCat-Video-Avatar 1.5 is included because its source materials show an inspectable avatar-video workflow with audio input, image conditioning, multi-person examples, and longer video continuation, making it useful for readers comparing generative media tools beyond simple short clips.
