Runway's GWM Worlds 2 Introduces Real-Time WorldPrompt Control
Runway introduced GWM Worlds 2, a research preview that turns high-fidelity video and audio generation into real-time interactive simulation. The model uses an autoregressive diffusion approach and features WorldPrompt, a new input format allowing users to fix aspects of a simulated environment and create timestamped events, enabling detailed control over characters, cameras, and the environment. The model generates 720p video at 24fps and 48kHz audio in real-time. Runway positions GWM Worlds 2 as a step toward fully self-generated, real-time games and experiences, with potential applications in gaming, robotics, and synthetic data generation for AI agents. CTO Kamil Sindi and Principal Research Scientist Robin Kahlow discuss technical challenges including error accumulation, long-term memory, and counterfactual generation. Runway is reportedly valued at $5.3 billion.
Major platform (Runway) releases a technical advance in real-time world models, which has significant implications for AI-driven content and simulation in ad tech.

Nvidia Demonstrates Real-Time AI Video for Agencies
Nvidia showcased a real-time, high-end AI video capability at Runway’s AI Summit, positioning the technology to advertising and entertainment industries. Using Nvidia’s latest computing platform, Runway demonstrated video-generation models that update scenes instantly as text prompts change, reducing generation times from minutes toward real-time. Nvidia framed the speed gains as transformative for creative workflows, suggesting creators will move from hands-on producers toward curators who direct outputs interactively. Richard Kerris, vice president and general manager of media and entertainment at Nvidia, is quoted emphasizing the impact of the increased speed and the role of agentic AI in enabling conversational interactions with systems.
Google DeepMind Launches Genie 4 World Model with Audio
The newsletter from Import AI covers Realtime-Bench, a benchmark for low-latency AI tasks, a Defense Intelligence Agency report on space security threats, Metis's paper on neuro-symbolic reasoning, and Google DeepMind's Genie 4. Genie 4, a world model generating real-time interactive 3D worlds with synchronized audio, music, and dialogue, is available as a research preview, with broader access via Project Genie, Google AI Ultra, and Gemini API/AI Studio. It maintains scene consistency for up to two minutes, features improved physics and multimodal generation, allows real-time natural language modifications, and uses Gemini as an AI director, with content watermarked by SynthID. Applications span gaming, learning, film, journalism, and robotics. Realtime-Bench tests AI on 50 interactive tasks, finding the best models lag behind human real-time performance. The DIA report highlights anti-satellite weapons and space-based nuclear risks, while Metis advocates fusing symbolic and neural reasoning for more reliable AI.
Runway CEO: AI Could Produce 50 Films for $100M
Cristóbal Valenzuela, co-founder and CEO of AI video-generation company Runway, said at the Semafor World Economy event that studios could reallocate a single $100 million budget across roughly 50 films using AI tools to maintain visual quality while increasing output and hit probability. Runway, valued at over $5 billion, is developing "AI world models" to speed pre-production, scripting, planning and visual effects, which Valenzuela says is already lowering production costs for some projects. The article cites examples including a forthcoming AI-assisted $70 million film, reporting that AI reduced its estimated $300 million cost. Valenzuela acknowledged controversy about AI in creative industries but argued skepticism is easing as tools prove practical. The piece notes dissenting views about whether scale will yield better art and corrects one of Valenzuela's citations about global book publishing figures.
