What is Longcat Full Quality?
Longcat Full Quality is an open-source, 13.6-billion-parameter video generation model developed by Meituan. Built on a Diffusion Transformer (DiT) architecture, it excels at producing highly coherent, high-quality videos. On Venice, it supports text-to-video generation at 720p resolution with flexible aspect ratios and clip lengths up to 30 seconds.
Use it privately on Venice
On Venice, you can generate videos with Longcat completely privately under our zero-retention policy, ensuring your creative prompts remain entirely your own. Venice offers an uncensored environment for this open-weights model, allowing unrestricted creative freedom. Instead of expensive subscriptions, you pay only per clip, making high-fidelity video generation highly accessible.
What can it do?
- •Strong temporal coherence and visual consistency across longer video durations.
- •Fully open-weights model under the permissive MIT license, ensuring user sovereignty.
- •Unified Diffusion Transformer (DiT) architecture optimized with Block Sparse Attention for efficient inference.
- •Trained with multi-reward RLHF (GRPO) for superior prompt alignment and natural motion.
- •No audio generation support natively on Venice.
- •Maximum resolution is currently capped at 720p on the platform.
- •Can be computationally intensive to run locally compared to smaller video models.
How to use it via API

Longcat Full Quality vs alternatives
| Model | Max resolution | Open weights | Uncensored | Price (Venice) |
|---|---|---|---|---|
| Longcat Full Quality | 720p | Yes | Yes | from $0.25 |
| Wan 2.7 | 720p | Yes | Yes | from $0.55 |
| Grok Imagine Private | — | No | Yes | from $0.32 |
Excellent temporal coherence and open-source flexibility.
What is it good for?
- •Creating cinematic B-roll and atmospheric video clips from text descriptions.
- •Generating social media video assets in 9:16, 16:9, or 1:1 aspect ratios.
- •Prototyping visual concepts and storyboards privately without subscription lock-in.
Prompting tips
- •Be descriptive with motion and lighting cues to leverage the DiT architecture's spatial understanding.
- •Choose the 9:16 aspect ratio for mobile-first platforms, or 16:9 for cinematic widescreen outputs.
- •Start with shorter 5-second clips to test your prompt composition before committing to longer 30-second generations.

Frequently asked questions
Longcat Full Quality is an open-source, 13.6-billion-parameter video generation model developed by Meituan. It uses a Diffusion Transformer (DiT) architecture to generate high-quality, coherent video clips from text prompts.
On Venice, you pay per clip starting from $0.25 for a 720p, 5-second video. The price scales with the selected clip duration (up to 30 seconds).
Yes, Longcat is fully open-source under the MIT license. On Venice, you can try it using free daily account credits, or pay per clip for heavier usage.
No, Longcat currently generates silent video clips. You will need to add audio or sound effects in post-production.
Longcat supports three main aspect ratios on Venice: 16:9 (widescreen), 9:16 (vertical/mobile), and 1:1 (square).
Longcat excels at temporal coherence and is natively pretrained for video continuation, making it highly stable. Wan 2.7 is another excellent open-weights alternative with distinct aesthetic qualities.
Yes. Venice operates under a strict zero-retention policy. Your prompts and generated videos are never stored, profiled, or used to train models.
Yes. Alongside the text-to-video model (longcat-text-to-video), Venice hosts longcat-image-to-video, which animates a still image into a moving clip. Both variants render at 720p, support clip durations of 5, 10, 15, 20, or 30 seconds, and run privately with zero prompt retention.
