I generated this 5s 1080p video in 4.5s
Real-time 1080p video generation achieved on a single NVIDIA B200 GPU, with consumer 5090 support coming.
The Fastvideo team has achieved a significant breakthrough in AI video generation speed, demonstrating their LTX-2.3 model creating a 5-second, 1080p video in just 4.5 seconds. This feat, performed on a single NVIDIA B200 data center GPU, marks a leap toward real-time, high-resolution video synthesis. The team credits extensive optimization across their pipeline for this performance. While the B200 is a powerful enterprise-grade chip, Fastvideo is actively working to port their optimization techniques to the upcoming consumer-grade NVIDIA GeForce RTX 5090, aiming to make high-speed generation more accessible.
A live demo is available for the public to experience the generation speed directly. The team has announced plans to open-source their work, allowing developers and researchers to build upon their optimizations. This move could accelerate wider innovation in efficient video generation models. The progress suggests a near future where generating short, high-quality video clips could become as instantaneous as generating a still image is today, potentially unlocking new creative and commercial applications.
- Generates 5-second 1080p video in under 5 seconds (4.5s) for real-time speeds.
- Runs on a single NVIDIA B200 GPU, with optimizations being adapted for RTX 5090s.
- Team plans to open-source the technology and has a live demo available for testing.
