InternUtopia

Shanghai AI Lab's city-scale embodied-AI simulation platform built on Isaac Sim, formerly named GRUtopia.

InternUtopia was developed by Shanghai AI Lab, previously named GRUtopia (Chinese name 浦源·桃源); it was released with a public paper at the World Artificial Intelligence Conference in July 2024, shipped version 2.0 in February 2025, and was renamed to InternUtopia with version 2.2.0 in July of that year. It's built on top of NVIDIA Isaac Sim and has three parts: GRScenes, a scene library of about 100,000 finely annotated interactive scenes across 89 categories, extending from homes to service settings like supermarkets and hospitals; GRResidents, virtual residents (NPCs) driven by a large language model that can converse with a robot and generate tasks; and the GRBench benchmark, focused on legged robots, with three task categories — object navigation, social navigation, and mobile manipulation. The platform also supports VR teleoperation and hand motion-capture control, and is used together with companion projects InternNav and InternManip.

ExampleIn GRBench's social-navigation task, a robot can ask a GRResidents-driven virtual resident for information about a target object before walking to its location.
