LongCat Avatar Is Live on WaveSpeedAI: Ultra-Realistic Lip-Synced Avatar Videos Up to 2 Minutes
AI avatar video generation has come a long way—but most tools still struggle with the same core problems: short clip limits, unstable identity, unnatural facial motion, and lip sync that looks slightly “off” the moment the audio gets complex.
LongCat Avatar is built to solve those exact issues.
Now available on WaveSpeedAI (wavespeed-ai/longcat-avatar), LongCat Avatar transforms a single photo and an audio track into super-realistic, lip-synchronized talking or singing avatar videos, with natural dynamics and consistent identity—for up to 2 minutes per generation.
Whether you’re building a virtual presenter, producing character-driven content, or generating long-form voice-based videos at scale, LongCat Avatar is designed to deliver results that feel convincingly human.
Why LongCat Avatar Stands Out
1. Precise Lip Sync That Holds Up in Real Speech and Singing
LongCat Avatar delivers lip synchronization that matches not only timing, but also pronunciation and rhythm—so speech feels correctly articulated instead of loosely animated. It keeps mouth movement aligned even when the audio becomes fast, emotional, or musically expressive, making it reliable for both talking head videos and singing performances. This level of accuracy is especially important for content where viewers naturally focus on facial detail.
2. Consistent Identity and Visual Stability Across Long Clips
Many avatar models look convincing for a few seconds, then drift: facial proportions subtly shift, expressions feel inconsistent, or visual quality fluctuates across frames. LongCat Avatar is designed to preserve identity and maintain stable visual consistency throughout the entire clip. That means the subject remains recognizably the same person from start to finish—an essential requirement for presenters, characters, and branded content.
3. Long-Form Generation Up to 2 Minutes, Built for Real Workflows
Most avatar tools are optimized for short demos, but real production needs longer outputs—narration, scripts, tutorials, storytelling, and multi-language voice tracks. LongCat Avatar supports up to 120 seconds per job, enabling longer-form content creation without stitching dozens of short clips together. Combined with natural head movement and expressive facial dynamics, it delivers results that are practical for actual workflows—not just quick tests.
Built for Creators and Developers
LongCat Avatar is a strong fit for both creators and engineering teams:
- Marketing and product demos — turn a script into a human-like presenter
- Education and learning content — create speaking tutors or instructors
- Music and singing avatars — generate performance-style videos
- Localization workflows — produce avatar content in multiple languages
- Character and storytelling formats — build consistent speaking characters
- API-driven pipelines — automate avatar generation at scale
Pricing and Output Options
LongCat Avatar supports two output tiers, both with a maximum length of 2 minutes:
| Output Tier | Details | Max Length |
|---|---|---|
| Standard | Default output, balanced quality and speed | 2 minutes |
| HD (720p) | Higher resolution for enhanced visual detail | 2 minutes |
Billing is transparent and predictable:
- Standard rate: $0.03/sec
- HD (720p) rate: $0.06/sec
- Minimum charge: 5 seconds
- Billing cap: 120 seconds
Production Notes
LongCat Avatar is designed for realistic, high-quality results, and generation time can vary depending on output length, resolution, and queue load. In typical cases, processing takes approximately 10–30 seconds of wall time per 1 second of video.
Available Now on WaveSpeedAI
LongCat Avatar is available via WaveSpeedAI as a ready-to-use REST API, with fast response, no cold starts, and cost-efficient pricing—making it easy to test quickly or integrate into real workflows.
