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).

System Requirements and Performance

This section discusses the various configurations and inference runtimes for GR00T N1.7 tasks. We discuss both latency and speedup.

GR00T N1.7 Inference Timing (4 denoising steps, 1 camera):

Note: Orin uses DiT-only TensorRT (--inference-mode tensorrt) because TRT 10.3 does not support the backbone engine. All other platforms use the full pipeline (--inference-mode trt_full_pipeline).
