3 NEW AI Video Models Released This Week
Comparing Alibaba Wan 2.6, ByteDance Seedance 1.5 Pro, and LongCat Video Avatar
3 NEW AI Video Models Compared: Wan 2.6 vs Seedance 1.5 Pro vs LongCat Avatar
This week has been absolutely packed with AI video releases. Three major announcements dropped: Alibaba's Wan 2.6, ByteDance's Seedance 1.5 Pro, and LongCat Video Avatar. Two of these are closed source, one is fully open source. Let's break down what each one does and which ones are actually worth your time.
TL;DR
| Feature | Wan 2.6 | Seedance 1.5 Pro | LongCat Avatar |
|---|---|---|---|
| Source | Closed | Closed | Open Source (MIT) |
| Cost | Vendor pricing | Vendor pricing | MIT weights, local GPU |
| Audio | Yes | Yes | Yes |
| Max Resolution | 1080p | 1080p | 720p |
| Best For | Reference-to-video | Quality video+audio | Talking/singing videos |
| Local Running | No | No | Yes |
Alibaba Wan 2.6: Reference-to-Video
What's New
Alibaba's Wan 2.6 generates video with audio up to 1080p resolution. Key features include:
- Pretty good lip sync capability
- Multi-shot videos with smooth transitions
- Up to 15 seconds per generation
- NEW: Reference-to-video feature
Reference-to-Video Explained
Instead of just uploading an image of a character, you can now upload a reference video of a character. Wan 2.6 can generate a new video of that character in a completely different scenario.
The character consistency is maintained across different scenes and actions. The model understands the character from the reference video and recreates them in new contexts.
Honest Assessment
Wan 2.6 is a marginal upgrade from Wan 2.5, which does largely the same thing. There's still noticeable noise and errors in generations, and being closed source means no local control.
Compared to leading closed models like Veo 3 or Sora 2, Wan 2.6 doesn't quite match up in terms of quality.
Where to try: Available free on Alibaba's native platform with free credits to start.
ByteDance Seedance 1.5 Pro: Quality Champion
Why It's Better Than Wan 2.6
Seedance 1.5 Pro also creates videos with audio, but the quality is noticeably higher:
- Smooth, consistent motion
- Clean aesthetics
- Natural audio integration
- Better lip sync accuracy
Benchmark Performance
Comparing across multiple metrics:
| Metric | Seedance 1.5 Pro vs Competition |
|---|---|
| Aesthetics | Outperforms Kling 2.0 and Veo 3.1 |
| Motion Quality | Best-in-class smoothness |
| Prompt Alignment | Highest accuracy |
| Audio Quality | Better sync than competitors |
| Audio Integration | Most natural feel |
Seedance 1.5 Pro (the teal color in benchmarks) consistently shows the largest area across all comparison metrics, outperforming competitors in aesthetics, motion, and alignment.
Audio Excellence
The audio benchmarks show Seedance 1.5 Pro beating both Kling and Veo in:
- Audio quality
- Synchronization accuracy
- Natural integration feel
Verdict: If choosing between Wan 2.6 and Seedance 1.5 Pro, Seedance is the clear winner in terms of quality.
Where to try: Available on the Dreamina platform.
LongCat Video Avatar: The Open-Source Winner
Why This Is the Most Exciting Release
The Chinese food delivery company Meituan continues to ship impressive AI tools. LongCat Video Avatar is now the best open-source tool for generating talking or singing videos.
How It Works
LongCat Avatar takes three inputs:
- Audio clip of what you want the person to say
- Photo of the character
- Text prompt for additional context
It merges all inputs together into a seamless video output.

Audio Subtleties:

- Natural eye blinking

Singing Videos:

Practical Recommendations
Choose Seedance 1.5 Pro If:
- Quality is your top priority
- You're creating commercial content
- You need the best audio integration
- Platform restrictions don't bother you
Choose Wan 2.6 If:
- You need reference-to-video capability

The Bigger Picture
This week's releases show the AI video landscape fragmenting into specialties:
- Closed platforms (Seedance, Wan) compete on raw quality
- Open source (LongCat) competes on accessibility and freedom
- Specialized models (Avatar tools) serve specific use cases better than generalists
For creators, this means choosing tools based on your specific needs rather than looking for one solution that does everything.
