Description:

NVIDIA Isaac GR00T N1.7 is an open foundation model for generalized humanoid robot reasoning and skills. This cross-embodiment model takes multimodal input, including language and images, to perform manipulation tasks in diverse environments. Developers and researchers can post-train GR00T N1.7 with real or synthetic data for their specific humanoid robot or task.

Isaac GR00T N1.7 is the medium-sized version of our model built using pre-trained vision and language encoders, and uses a flow matching action transformer to model a chunk of actions conditioned on vision, language and proprioception.

A detailed description of the Isaac GR00T N1.X architecture is provided in the GROOT N1 White Paper (https://arxiv.org/abs/2503.14734).

This model is ready for commercial/non-commercial use.

Cumulative Compute: Follow Instructions Estimated Energy and Emissions for Model Training: Follow Instructions Total kWh: 64 GB200 nodes * 4 gpus per node x 1200W x 0.001 x 0.8 x 120 hours * 1.4 = 41288 kWh Total Emission: 410.5 * 41288 * 0.000001 = 16.949 tCO2e

Model Architecture:

GR00T-N1.7 VLM backbone is now Cosmos-Reason2-2B

Network Architecture:

The schematic diagram is shown in the illustration above. Red, Green, Blue (RGB) camera frames are processed through a pre-trained vision transformer (SigLip2). Text is encoded by a pre-trained transformer (T5) Robot proprioception is encoded using a multi-layer perceptron (MLP) indexed by the embodiment ID. To handle variable-dimension proprioception, inputs are padded to a configurable max length before feeding into the MLP. Actions are encoded and velocity predictions decoded by an MLP, one per unique embodiment. The flow matching transformer is implemented as a diffusion transformer (DiT), in which the diffusion step conditioning is implemented using adaptive layernorm (AdaLN).
