Runway has shared research into real-time video generation, where users would stream videos as they describe them instead of entering a prompt and waiting. Runway says users repeatedly report losing the most time generating and revising videos, and it wants to minimize the time to the first frame, then stream video as users prompt it. The approach was first discussed in March with Runway Characters, using GWM-1, the company's first "General World Model," introduced in December 2025. GWM-1 builds on Gen-4.5, generates video frame by frame, and accepts camera movements, robot commands, or audio as controls. Runway recently showed Solaris, which uses Gen-4.5 to generate user interfaces frame by frame and responds to clicks or voice input. Runway argues real-time generation closes the gap between an idea and its execution and points to lower costs, since faster models use less GPU time. Runway says its real-time models generate each new segment using all previously generated frames as context, and it addresses compounding errors by training the model on its own outputs rather than only error-free inputs. Runway sees education, gaming, and robotics as key use cases.
