Visko Unveils Real-Time 4K Video AI
๐กSee how Orbis combines 4K real-time generation with prompt changes during an active video stream.
โก 30-Second TL;DR
What Changed
Orbis generates AI video in real time.
Why It Matters
Orbis could enable more interactive video-generation experiences, particularly for creative tools and live visual applications. Real-time prompt editing may reduce iteration time compared with stop-and-restart workflows.
What To Do Next
Evaluate Orbis with a short interactive-video prototype, measuring stream continuity, prompt-change latency, and 4K output quality.
Key Points
- โขOrbis generates AI video in real time.
- โขThe model supports 4K video output.
- โขPrompt changes can be applied without stopping the active stream.

๐ Enhanced Key Takeaways
- โขVisko secured $10 million in pre-seed funding led by Llama Ventures to support the development of the Orbis model.
- โขThe system utilizes a bounded multi-scale memory layer to maintain visual consistency and prevent temporal artifacts during hour-long generation sessions.
- โขOrbis operates at 24 frames per second (FPS) by integrating a specialized GPU serving engine with a dedicated streaming upscaler.
- โขThe company was founded in 2025 by CEO Qing (Will) Yin, a former Apple researcher and Stanford Ph.D. graduate.
- โขThe model architecture is governed by Neural Stochastic Differential Equations (Neural SDEs) to ensure physical plausibility and temporal stability.

๐ ๏ธ Technical Deep Dive
- Model Architecture: Utilizes Neural Stochastic Differential Equations (Neural SDEs) for continuous-time dynamics.
- Memory Management: Employs a bounded multi-scale memory layer to preserve subject and scene coherence over extended durations.
- Rendering Pipeline: Combines an optimized GPU serving engine with a streaming upscaler to achieve 4K output at 24 FPS.
- Statefulness: Designed as a 'Live Model' rather than a discrete clip generator, allowing for continuous, stateful video streams.
