What is Waypoint 1.5?
Waypoint 1.5 is a real-time interactive video world model from Overworld, a Providence, Rhode Island start-up formerly called Wayfarer Labs. Released on 9 April 2026, it takes a starting image and your keyboard and mouse input and generates the next frames as you play, entirely on your own GPU.
The main model has 1.2 billion parameters and a 512-frame context, about 10 seconds of play, up from 2 seconds in Waypoint 1. It comes in two tiers: a 720p model and a 360p model for weaker gaming PCs. Overworld says it was trained on nearly 100 times more data than Waypoint 1.
The weights are Apache 2.0. Overworld also offers Biome, a desktop app with an installer, the World Engine inference library, and Overworld.stream, which runs the model in the cloud from a browser.
Is Waypoint 1.5 worth it?
Waypoint 1.5 is an open world model built for a gaming PC rather than a data centre. On an RTX 5090 it generates 720p at 56 frames per second, or 72 with 8-bit quantisation, and an RTX 3090 manages 30 at 8-bit. That is the speed of a real game, on hardware many players own, with no server bill.
It is also the easiest to try. Biome installs like a game and lets you pick a scene and walk; Overworld.stream does the same in a browser. Apache 2.0 weights and a Diffusers pipeline mean a developer can build on it without a licence negotiation, which is not true of Tencent's WorldPlay or Ant Group's LingBot-World 2.0.
The catch: memory. The 512-frame context covers about 10 seconds, so anything you walked past longer ago is regenerated, not remembered. The model card lists drift, collapse, unstable geometry and objects that fail to persist on long sessions. There are no published quality benchmarks against other world models, only speed figures, and the company is small: a $4.5 million pre-seed round in January 2026. Adoption is early, with 70 likes and about 8,000 total downloads for the 720p model.
Our take: Waypoint is a toy in the best sense, the place to feel what a generated game is like this year on your own machine; the games themselves still need an engine that remembers.
Where it earns its place
An indie developer exploring AI-native game ideas
Prototype a walkable dream-like level from a single piece of concept art
Load Overworld/Waypoint-1.5-1B through the Diffusers modular pipeline on an RTX 5090, seed it with the concept image and drive it with WASD; Apache 2.0 means a prototype can become a product.

Install Biome on a gaming PC, or open Overworld.stream in a browser, and play from the scene gallery; no code and no cloud bill for the local version.
Before you commit
- Setup
- Install Biome from over.world and pick a scene; developers can load the checkpoint with Diffusers ModularPipeline or the World Engine library.
- Integrations
- Hugging Face Diffusers (modular pipeline), World Engine library, Biome desktop app, Overworld.stream.
- Data and privacy
- Runs locally under Apache 2.0, so your inputs stay on your PC; the hosted Overworld.stream runs in Overworld's cloud.
- Cost at scale
- One consumer GPU per player locally; Overworld.stream pricing is not published.
- Limits
- 10-second context; drift on long rollouts; RTX 30 series or later for 720p; no physics guarantees.
What’s good
- 56 fps at 720p on an RTX 5090; 30 fps on an RTX 3090 at 8-bit
- Apache 2.0 weights, commercial use allowed
- Desktop installer and browser version for non-developers
- 360p tier for weaker gaming PCs
What’s not
- About 10 seconds of memory
- Drift and unstable geometry on long sessions
- No published quality benchmarks
- Small, early-stage company
Best for
Developers and curious players with a recent NVIDIA gaming GPU who want to run a generated, playable world locally.
