# Framepack AI: The Revolutionary AI Video Generation Model Framepack AI is a breakthrough neural network structure for AI video generation. It employs innovative "next frame prediction" technology combined with a unique fixed-length context compression mechanism, enabling users to generate high-quality, high-framerate (30fps) videos up to 120 seconds long with very low hardware barriers (requiring only consumer-grade NVIDIA GPUs with 6GB of VRAM). ## What Makes Framepack AI Unique? The core innovation of Framepack AI lies in its **fixed-length context compression** technology. In traditional video generation models, context length grows linearly with video duration, leading to a sharp increase in VRAM and computational resource demand. Framepack AI effectively solves this challenge by intelligently evaluating the importance of input frames and compressing this information into fixed-length context 'notes'. This significantly reduces the demand for VRAM and computational resources, making it possible to generate long videos on consumer hardware. ## Key Features * **Fixed-Length Context Compression**: Intelligently compresses all input frames into fixed-length context information, preventing memory usage from scaling with video length and dramatically reducing VRAM requirements. * **Minimal Hardware Requirements**: Requires an NVIDIA RTX 30XX, 40XX, or 50XX series GPU with at least 6GB of VRAM. Compatible with both Windows and Linux operating systems, supporting FP16 and BF16 data formats. * **Efficient Generation**: Generates frames at approximately 2.5 seconds per frame on RTX 4090 desktop GPUs, with optimization (like teacache) reducing this to 1.5 seconds per frame. * **Strong Anti-Drift Capabilities**: Progressive compression and differential handling of frames by importance mitigates the 'drift' phenomenon common in long video generation, ensuring consistent quality throughout. * **Multiple Attention Mechanisms**: Support for PyTorch attention, xformers, flash-attn, and sage-attention provides flexible optimization options for different hardware setups. * **Open-Source and Free**: Developed by ControlNet creator Lvmin Zhang and Stanford University professor Maneesh Agrawala. Framepack AI is a fully open-source project with its code and models publicly available on GitHub, backed by an active community and rich ecosystem. ## Getting Started with Framepack AI You can download Framepack AI from its official GitHub repository. It can be used as a standalone application or integrated with platforms like ComfyUI. The community, such as RunningHub, has also created a Framepack plugin for zero-threshold usage.
