Fable51 Worlds is an open-source, AI-assisted world-generation project that turns a text brief, photograph, or video into a walkable browser scene implemented as a pure Three.js application. Claude Fable 5.1 agent swarms research the location, collecting map geometry, elevation, transit, street information, and storefront data; generation scripts produce procedural façades, street furniture, vehicles, vegetation, fixtures, and other assets; and the runtime assembles terrain, streets, buildings, props, crowds, and traffic from JSON specifications without a game engine, proprietary 3D tiles, or downloaded meshes. Verification uses Playwright to drive the application, capture fixed viewpoints, and compare them with photographs from corresponding locations. Independent reviewer agents covering architecture, geography, technical art, and interaction produce reports for subsequent fix cycles, and each world includes a quality-assurance report.

Infinite World is an open-source system for building persistent worlds with multimodal AI. It combines multimodal understanding, world simulation, and interaction in a continuous loop: prompts, images, or other inputs are interpreted into world state, rules, and possible actions; generated scenes respond to that state; and people, agents, and events can update the world. The runtime records scenes, choices, state changes, history, and branches so worlds can preserve context across scenes and be replayed. The project supports text, voice, and image interaction, local previews, saved-branch replay, and cached generated video. Its current local setup uses a Node.js and pnpm workspace, with FFmpeg and whisper.cpp for voice transcription and live output. Interactive live streaming is in development, while additional inputs such as chat, audio, mouse, and keyboard are planned. The repository describes the project as early development, with APIs and stored data subject to change, and distributes it under the Apache License 2.0.

Google 3D Tiles is a Google service that provides 3D geographic tiles covering the globe.

scroll-world is an agent skill for Claude Code, Codex, and other SKILL.md-compatible agents that builds scroll-scrubbed 3D world landing pages for brands and industries. It generates cohesive isometric diorama scenes and image-to-video camera flights, linking scenes through first/last-frame conditioning so the camera appears to move continuously as the visitor scrolls. The skill provides prompt templates, an AI image and video rendering pipeline using Higgsfield, Monid, Seedance, Kling, or Codex image generation, and a framework-agnostic vanilla JavaScript scrubbing engine that can be used with plain HTML, Next.js, Vue, or a Python-served page. It can also render a separate portrait chain for mobile devices and requires external rendering services or CLIs, ffmpeg/ffprobe, and Python with Pillow.

LingBot-World 2.0, also called LingBot-World-Infinity, is an AI world-modeling system from the Robbyant Team for generating interactive video environments. Its causal pretraining paradigm is designed for an unbounded interaction horizon, while a distilled real-time variant is claimed to drive 720p video streams at 60 frames per second. The system supports diverse actions, including attacking, archery, spell-casting, and shooting, along with text-driven events. Its agentic harness uses a pilot agent to plan and execute character behavior and a director agent to synthesize new environmental elements as a scene progresses. The causal inference implementation processes video frames chunk by chunk with KV caching rather than processing the entire sequence at once. The release provides inference code and model weights, including a 14B causal-fast model, with a codebase built on Wan2.2; models are distributed through Hugging Face and ModelScope, and the real-time system can be tried through Reactor on the web or LingGuang on mobile. The project is licensed under CC BY-NC-SA 4.0 for non-commercial use. It states that deployment code will not be released and points to SGLang or flashdreams for self-deployment references.
