Introduction
- TL;DR: Krea AI released Krea Realtime 14B on October 14, 2024 — a 14B parameter open-source autoregressive text-to-video model capable of real-time, long-form generation at 11fps on a single NVIDIA B200 GPU. Built with Self-Forcing distillation from Wan 2.1 14B, it marks a major leap for real-time video synthesis and interactive AI creation.
- Krea Realtime 14B redefines open-source video generation with its ability to stream frames as it generates them, supporting live prompt changes and restyling in real-time.
Architecture and Techniques
Krea Realtime 14B uses the Self-Forcing method to convert Wan 2.1 14B into an autoregressive model. It introduces advanced techniques like KV Cache Re-computation and Attention Biasing, reducing error accumulation during long-form rendering.
Why it matters: This is the first open-source model to combine 14B-scale performance with interactive, low-latency text-to-video generation.
Real-Time Capabilities
Running at 11fps with 4 inference steps on a single B200 GPU, it streams the first frame in about one second, enabling users to adjust prompts or styles mid-generation.
Why it matters: This transforms generative video AI from batch rendering into an interactive creative medium.
Deployment
Developers can clone from Hugging Face (krea/krea-realtime-video) and launch a local server with a few lines of code. Integration with diffusers allows advanced modular workflows.
Why it matters: Open availability under the Apache 2.0 license empowers both researchers and commercial creators to iterate freely.
Comparison with Prior Models
| Model | Parameters | Architecture | FPS (B200) | Open Source |
|---|---|---|---|---|
| Krea Realtime 14B | 14B | Autoregressive | 11fps | Yes |
| Wan 2.1 T2V | 1.3B | Diffusion | <1fps | Partial |
| Pika 1.5 | Unknown | Diffusion | ~1fps | No |
| Runway Gen-3 | Unknown | Diffusion | ~1fps | No |
Why it matters: Krea Realtime 14B outpaces prior open models by a full order of magnitude, bridging large-scale fidelity with real-time responsiveness.
Conclusion
The Krea Realtime 14B model represents a significant breakthrough in open-source text-to-video generation. With its 14B parameter autoregressive architecture, real-time 11fps generation capability on B200 GPU, and full Apache 2.0 licensing, it provides researchers and developers with a powerful tool for interactive video creation. The Self-Forcing technique and advanced optimization methods enable both high-quality output and responsive, real-time performance, marking a major advancement in accessible video AI technology.
