Cosmos contains\n\n1. Pre-trained models (available via Hugging Face) under the [NVIDIA Open Model License](https://www.nvidia.com/en-us/agreements/enterprise-software/nvidia-open-model-license/) that allows commercial use of the models for free.\n2. Training scripts under the [Apache 2 License](https://www.apache.org/licenses/LICENSE-2.0) for post-training the models for various downstream Physical AI applications.\n\n## Key Features\n\nCosmos-Transfer1 is a pre-trained, diffusion-based conditional world model designed for multimodal, controllable world generation. It creates world simulations based on multiple spatial control inputs across various modalities, such as segmentation, depth, and edge maps. Cosmos-Transfer1 offers the flexibility to weight different conditional inputs differently at varying spatial locations and temporal instances, enabling highly customizable world generation. This capability is particularly useful for various world-to-world transfer applications, including Sim2Real.\n\nThe model is available via [Hugging Face](https://huggingface.co/collections/nvidia/cosmos-transfer1-67c9d328196453be6e568d3e). The post-training scripts will be released soon!\n\n## Examples\n\n* [Installation instructions and inference examples for Cosmos-Transfer1-7B](examples/inference_cosmos_transfer1_7b.md)\n* [Installation instructions and inference examples for Cosmos-Transfer1-7B-Sample-AV](examples/inference_cosmos_transfer1_7b_sample_av.md)\n* [Installation instructions and inference examples for Cosmos-Transfer1-7B-4KUpscaler](examples/inference_cosmos_transfer1_7b_4kupscaler.md)\n* Cosmos-Transfer1 post-training is coming soon!\n\nThe code snippet below provides a gist of the inference usage.\n\n```bash\nexport CUDA_VISIBLE_DEVICES=0\nexport CHECKPOINT_DIR=\"${CHECKPOINT_DIR:=./checkpoints}\"\nCUDA_HOME=$CONDA_PREFIX PYTHONPATH=$(pwd) python cosmos_transfer1/diffusion/inference/transfer.py \\\n    --checkpoint_dir $CHECKPOINT_DIR \\\n    --video_save_folder outputs/robot_sample \\\n    --controlnet_specs assets/robot_sample_spec.json \\\n    --offload_text_encoder_model\n```\n\n\u003cp align=\"center\"\u003e\n\u003cvideo src=\"https://github.com/user-attachments/assets/54994029-18a9-4e79-859b-e6325179fdb7\"\u003e\n  Your browser does not support the video tag.\n\u003c/video\u003e\n\u003c/p\u003e\n\n\u003cp align=\"center\"\u003e\n\u003cvideo src=\"https://github.com/user-attachments/assets/55daed44-5a2d-4af1-b547-e610f5ff32c6\"\u003e\n  Your browser does not support the video tag.\n\u003c/video\u003e\n\u003c/p\u003e\n\n## Model Family\n\n| Model name | Description | Try it out | Supported Hardware |\n|------------|----------|----------|----------|\n| [Cosmos-Transfer1-7B](https://huggingface.co/nvidia/Cosmos-Transfer1-7B) | World Generation with Adaptive Multimodal Control |[Inference](examples/inference_cosmos_transfer1_7b.md)   | 80GB H100 |\n| [Cosmos-Transfer1-7B-Sample-AV](https://huggingface.co/nvidia/Cosmos-Transfer1-7B-Sample-AV) | Cosmos-Transfer1 for autonomous vehicle tasks | [Inference](examples/inference_cosmos_transfer1_7b_sample_av.md) | 80GB H100 |\n\n\n## License and Contact\n\nThis project will download and install additional third-party open source software projects.
