What is Overworld Waypoint-1.5?

Waypoint-1.5 is a real-time diffusion world model built for the GPUs people actually own: a 1B-parameter dense model (plus a 360p variant) whose interactive video generation runs on consumer hardware, with open weights on Hugging Face and an arXiv paper behind it. It is the open-source, self-hostable counterweight to the datacenter realtime models above — the same "world you can steer live" idea without renting inference.

What Overworld Waypoint-1.5 does

Realtime diffusion world model — interactive video generated live as you steer
1B-parameter dense model, plus a 360p variant for lighter hardware
Runs on consumer-grade GPUs — no datacenter rental required
Open weights on Hugging Face (Waypoint-1.5-1B and 1.5-1B-360P)
Backed by an arXiv paper (2609.37107) and a Hugging Face write-up

Who is Overworld Waypoint-1.5 for?

Self-hosting a steerable realtime generated world on your own GPU
Experimenting with world-model research without renting cloud inference
Comparing open realtime world models against closed ones (Runway GWM, Genie 3)

Pros and cons of Overworld Waypoint-1.5

Pros

Open weights and a paper — the rare realtime world model you can actually download
Consumer-hardware focus makes self-hosted live worlds practical
Small (1B) footprint relative to frontier video models

Cons

1B-class output quality trails the frontier realtime models
Research-stage project — tooling and docs are thin
360p variant trades resolution for accessibility

Frequently asked questions

What is Waypoint-1.5?

Overworld’s realtime diffusion world model for interactive video generation on consumer-grade hardware, released with open weights in Sep 2026.

Is Waypoint-1.5 open source?

The weights are open on Hugging Face (Waypoint-1.5-1B and a 360P variant) with an arXiv paper; check the licence terms on the model cards before commercial use.
