Introducing Natura-1, our first general foundation model for the physical world. It follows natural-language instructions zero-shot and turns them into action with dexterous hands. Natura-1 is a 50-billion-parameter mixture-of-experts (MoE) model pretrained on one million hours of egocentric human experience. On top of this foundation, we conduct efficient post-training on a limited amount of robot data to adapt pretrained world knowledge to dexterous manipulation, yielding a model that generalizes to a wide range of unseen scenarios. Natura-1 follows complex natural-language instructions zero-shot, reasoning through spatial constraints, multi-object relationships, and negative conditions. It can also autonomously carry out long and continuous workflows to perform long-horizon executions. Natura-1 provides early evidence that generalization—and even emergent behavior—can coexist with the complexity of dexterous hands. Further progress depends on the full stack: infrastructure for faster training and real-time inference, pretraining data at greater scale and coverage, and models that transfer to robots with less adaptation. We expect it to be a long-term research and engineering effort.

Congratulations to the @naturewill team on the release of Natura-1! Natura-1 is a 50B-parameter MoE foundation model for the physical world, pretrained on one million hours of egocentric human experience. At Lightwheel, we’re proud to support Natura-1 through EgoSuite, providing high-quality human data at scale. Our data spans real-world tasks in homes, retail stores, hospitals, and factories, with precise bimanual hand-pose annotations and footage from wrist-mounted cameras. Real-world human experience, captured in detail and delivered at scale. #NatureWill #Natura1 #PhysicalAI #EgoSuite #HumanData

Full demos of six real-world tasks, all performed by Natura-1. Everyday work involves more than picking and placing rigid objects. Natura-1 demonstrates sustained autonomous execution across workflows that combine precise manipulation with multi-step coordination.

Introducing Natura-1, @naturewill's first general foundation model for the physical world. It is a single model that follows plain-language instructions zero-shot and carries them out with dexterous hands. - 50B MoE, pretrained on 1M hours of egocentric human experience. - Drives 20-DoF dexterous hands from plain language, zero-shot, in a 100ms loop. - Scaling human data from ~44K to 1M hours cut action MSE on held-out robot data by 67.7%. - Built on in-house data and compute infra, it handles fine-grained long-horizon tasks and a ~30-minute zero-shot interaction in one continuous take. The general model exists, and it can only get stronger. naturewill.com/blog/natura-1…

30 minutes. One take. No cuts. We put Natura-1’s zero-shot generalization to the test with complex spoken instructions and unfamiliar tasks and environments. It responds to new requests, adjusts and retries when an action fails, and keeps going autonomously.

With egocentric training data scaled from 44K to 1M hours, Natura-1 predicts actions more accurately on unseen human and robot data. Prediction MSE error on real-robot data falls by 67.7%, without fine-tuning on robot data.
