Visko Orbis and Runway GWM Worlds 2

Visko opened public access to Orbis 1.0 on September 1, 2026, a model that streams interactive video continuously at 4K and 24 fps, allows prompt changes mid-stream without restarting, and sustains sessions at hour-scale with persistent visual memory. An API is accessible via Reactor World. Visko also closed a $10 million pre-seed round led by Llama Ventures. Two days later, Runway shared GWM Worlds 2 as a research preview, generating continuous 720p video at 24 fps with synchronized 48,000 Hz audio and generated speech. Runway's model uses a structured input format called WorldPrompt that separates persistent world context from a timestamped stream of text actions, and supports first- and third-person navigation, multi-character dialogue, agentic control, multiplayer sessions via LiveKit, and LLM-assisted world authoring. GWM Worlds 2 remains a research preview without public access.
