LongLive
LongLive is an NVIDIA Labs infrastructure codebase for long video generation.
The repository presents LongLive 2.0 as NVFP4 and parallel infrastructure for long video generation, with training and inference support, multi-shot generation, sequence parallel inference, async decoding, model links, documentation, configs, papers, and demo materials. This page is a starting point, not a recommendation. Check the original source before relying on the resource.
What it is
Infrastructure for long video generation
LongLive is framed around the systems work needed for longer video generation rather than a simple consumer video editor or one-prompt app.
Why it stands out
Parallelism, NVFP4, and long sequences
The public materials focus on training and inference infrastructure, including sequence parallelism, NVFP4 paths, multi-shot support, async decoding, and streaming-oriented long-video workflows.
Availability
Repo, docs, models, and papers
The repository includes training and inference code, configuration files, documentation, model links, project pages, papers, and project-reported performance tables for readers comparing the technical direction.
Why it matters
Why readers may notice it
LongLive matters because AI video generation is pushing beyond short clips into longer, more interactive sequences. Its source materials show the infrastructure side of that shift: cache handling, streaming, parallel inference, quantized execution, and training support.
What readers may want to know
Where it fits
This belongs in the generative media layer. It is most relevant for readers following long video generation, real-time or interactive video systems, training infrastructure, inference optimization, and model deployment work rather than finished creative apps.
Reporting note
What appears notable
The repository highlights LongLive 2.0, NVFP4 training and inference paths, multi-shot support, sequence parallel inference, async decoding, LongLive 1.0 real-time interactive long-video work, ICLR 2026 acceptance, and project-reported FPS and VBench results.
Before using
What readers may want to review
Whether the goal is LongLive 2.0 infrastructure work or the older LongLive 1.0 branch.
The CUDA, GPU, model-checkpoint, NVFP4, TransformerEngine, FourOverSix, and configuration requirements for the intended setup.
The project-reported FPS, VBench, and model-table claims before using them as settled comparisons across video-generation systems.
Best fit
Who may find it relevant
Readers tracking long video generation and real-time or interactive video systems.
Builders comparing training and inference infrastructure for diffusion-based video generation.
Less relevant for readers looking for a no-code video generator or casual laptop-friendly creative workflow.
Editorial note
Why it is included here
LongLive is included because its source materials show the infrastructure side of long video generation, making it useful for readers comparing how video systems are being pushed toward longer, faster, and more interactive outputs.
