Runway Game Worlds
The name is a bit misleading.
It’s more like Runway Comics Worlds or even Runway’s Board Games.
Because it goes back to the roots — text-based control. It’s basically text adventures: you write a prompt, the game reacts, but also generates an image of what’s happening.
Text games without the need for your imagination.

*“Game Worlds uses new AI technologies for nonlinear storytelling. This means that each game session you play is generated in real time with personalized stories, characters, and multimodal media.
In the beta version, you can play both pre-made text adventures and create your own.”*

VibeVoice: a new text-to-speech (TTS) model for long-form conversations with multiple voices from Microsoft.
• 1.5B parameters
• MIT licensed
• Up to 1.5 hours of generation
• Strong emotional expressiveness
More details: VibeVoice is a new framework designed for creating expressive and extended audio recordings of conversations with multiple speakers (such as podcasts) from text. It addresses key issues of traditional text-to-speech (TTS) systems, particularly those related to scalability, speaker consistency, and natural turn-taking.
The model can synthesize up to 90 minutes of speech with up to 4 distinct speakers, exceeding the typical limitations of many previous models restricted to 1–2 speakers.
