To generate video with artificial intelligence, a user typically submits a prompt, waits, and then receives a finished clip that cannot be altered. Visko Platform Inc. today opened public access to Orbis, a foundation model that streams worlds in real time with persistent memory, interactivity, and physics-grounded generation for unlimited duration. The company has also raised $10 million in pre-seed funding led by Llama Ventures.
“Every real-time system before this faced the same wall: The longer a world runs, the more it falls apart,” stated Qing (Will) Yin, founder and CEO of Visko. “We built Orbis to hold together — physically, visually, and narratively — for as long as you want to stay inside it. Starting today, anyone can see that for themselves atvisko.ai.”
“Most video models optimize every frame of a clip at once and show nothing until the whole thing resolves,” Yin toldThe Robot Report. “Orbis finishes the first frame, streams it, then generates the next conditioned on what came before, closer to next-token prediction in a large language model.”
Visko was founded in 2025 by Yin, a Stanford Ph.D. in computational mathematics and mechanics who spent three years as a researcher at Apple. The Sunnyvale, Calif.-basedstartup‘s 16-person team draws from Apple,Google DeepMind, Meta, Amazon, and Tesla, and it is working with Google.
Visko said itsLive Modelsare a new class of world models that run rather than render. Where conventional AI video generates a clip and stops, the company said itsOrbisfoundation model generates video continuously and streams it live.
Users can change the prompt at any moment during generation and see the update reflected instantly while the video keeps streaming. “The next paradigm of AI is not a model you call, but a process that runs in step with the world itself,” Visko claimed.
According to the company’stechnical report, Orbis delivers 4K video at 24 frames per second in real time and sustains hour-scale generation without quality or color drift. “Generation is grounded in physical dynamics: A latent world model scores candidate futures during inference, steering output toward physically plausible motion and object dynamics,” said Visko.
“Change the prompt mid-run, and the world updates around it instead of restarting,” said Yin. “That makes it usable forsimulationand for training footage that is unsafe or expensive to stage. In short, we are the world’s first real-time 4K steerable video generation model, enabling use cases in interactive robotic training.”
“In addition to generating videos up to an hour long and enabling real-time commands, Orbis can generate videos in real time,” said Yin. “We designed the memory structure to directly embed physics frame by frame. This actually requires less compute, and egocentric data requires long-form video without any breaks.”
In the report’s evaluations, Orbis leads compared real-time and long-video systems on DOVER aesthetic and technical quality and on VideoAlignvisualand motion quality. Visko said it recorded the highest overall-preference and temporal-stability ratings in a long-form human preference study across eight systems.

Thereportalso disclosed dimensions where Orbis trails other systems, with full methodology and results published. There is more work to be done, acknowledged Yin.
