is an NVIDIA world foundation model for generating physics-aware videos from text prompts or an image prompt. The API exposes the Cosmos3 generator path and returns an MP4 video encoded as a base64 string. The hosted Preview API deployment includes safety guardrails and SynthID watermarking for generated video outputs. **Model Developer**: NVIDIA ## Input/Output Specifications **Input** - Text prompt. - Optional image input as base64, data URI, or public URL. - Optional generation controls including seed, resolution, frame count, fps, steps, guidance scale, and negative prompt. **Output** - Video. - MP4 container. - Base64 encoded response field: `b64_video`. ## Usage Send requests to the model endpoint with a JSON body: ```json { "prompt": "A robot moves through a clean industrial warehouse.", "resolution": "720_16_9", "num_output_frames": 189, "seed": 42 } ``` The response contains: ```json { "b64_video": "" } ``` ## License This model is released under the [NVIDIA Open Model License](https://www.nvidia.com/en-us/agreements/enterprise-software/nvidia-open-model-license/).

Developers should work with their internal teams to ensure the model meets requirements for the relevant industry and use case and addresses unforeseen product misuse.

Cosmos models generate and reason about world states that can be useful for robotics, autonomous vehicles, and simulation workflows. ## Cosmos3 Nano Cosmos3 Nano is the generator variant used by this Preview API endpoint. It accepts text prompts and optional image conditioning, then generates a short video. The hosted endpoint applies safety guardrails and SynthID watermarking to generated outputs. ## Risk Areas and Mitigations World foundation models can produce unrealistic outputs, unsafe content, or biased artifacts reflected in their training data. Hosted Cosmos endpoints use guardrail systems to reduce unsafe input and output behavior. Users should still review generated outputs before using them in downstream systems. ## Deployment Cosmos3 Nano is hosted by NVIDIA in the API Catalog as a managed Preview API endpoint. NVIDIA manages infrastructure, model deployment, and service-level controls such as authentication, monitoring, and rate limiting. ## Governing Terms Use of this trial service is governed by the NVIDIA API Trial Terms of Service. Use of the model is governed by the NVIDIA Open Model License. 38:[["$","div",".3",{"className":"relative","children":[["$","div",null,{"className":"relative flex min-h-[194px] w-full flex-col
