About this model
Longcat Full Quality is the text-to-video configuration of Meituan's LongCat-Video, a foundational generation model first detailed in the LongCat-Video Technical Report and released as open weights. It is built on the Diffusion Transformer (DiT) framework and uses a single unified architecture covering text-to-video, image-to-video, and video continuation, rather than separate task-specific models. The technical report places its parameters at roughly 13.6 billion in a dense configuration.
Its defining capability is long-form output: pretraining on video-continuation tasks is intended to maintain quality and temporal coherence across minutes-long videos, with sources describing coherent generation up to several minutes at 720p and 30fps. A coarse-to-fine generation strategy along both temporal and spatial axes targets efficient inference, producing clips within minutes according to the technical report.
Within the same family, this "Full Quality" path prioritizes fidelity, while the Longcat Distilled variant is optimized for faster, fewer-step inference. The family also includes an image-conditioned counterpart, Longcat Full Quality (Image-to-Video), and its distilled equivalent, Longcat Distilled.
All variants share the underlying LongCat-Video foundation and are distributed under the MIT License, which permits broad commercial and research use without granting rights to Meituan trademarks or patents. Because these configurations were released together, comparisons here are between siblings—quality-focused versus distilled, text-conditioned versus image-conditioned—rather than against an earlier generation.
