About
Robbyant Team [](https://technology.robbyant.com/lingbot-world) [](https://arxiv.org/abs/2601.20540) [](https://huggingface.co/robbyant/lingbot-world-base-cam) [](https://www.modelscope.cn/models/Robbyant/lingbot-world-base-cam) [](LICENSE.txt) We are excited to introduce LingBot-World, an open-sourced world simulator stemming from video generation. Positioned as a top-tier world model, LingBot-World offers the following features. - High-Fidelity & Diverse Environments: It maintains high fidelity and robust dynamics in a broad spectrum of environments, including realism, scientific contexts, cartoon styles, and beyond. - Long-Term Memory & Consistency: It enables a minute-level horizon while preserving contextual consistency over time, which is also known as long-term memory. - Real-Time Interactivity & Open Access: It supports real-time interactivity, achieving a latency of under 1 second when producing 16 frames per second. We provide public access to the code and model in an effort to narrow the divide between open-source and closed-source technologies. We believe our release will empower the community with practical applications across areas like content creation, gaming, and robot learning. 🎬 Video Demo Your browser does not support the video tag. 🔥 News - Jan 29, 2026: 🎉 We release the technical report, code, and models for LingBot-World.

How it works
Variants
Open weights ship in several sizes and precisions. One page, all the variants — pick the one that fits your GPU. VRAM figures are estimates from model size.

Using it via the API
Once AxForge deploys lingbot-world-fast for you, it answers on the OpenAI-compatible API — the same base URL and keys as every other model. (lingbot-world-fast below is illustrative; you get the exact model name on deployment.)
$ curl -sS https://api.axforge.ai/v1/videos/generations \
-H "Authorization: Bearer $AXFORGE_API_KEY" \
-H "Content-Type: application/json" \
-d '{"model":"lingbot-world-fast","prompt":"a drone shot over a forest"}'
Licence
Open weights under apache-2.0 — commercial use is permitted. Deploy it on AxForge EU hardware on request. Read the licence ↗
