 ## Model Architecture
 
 **Architecture Type:** Transformer
-
 **Network Architecture:** Mixture-of-Transformers (MoT)
 
-Cosmos3 is an Omni-modal foundation model built on a Mixture-of-Transformers (MoT) architecture consisting of two complementary transformer towers: an autoregressive transformer for discrete token generation and a diffusion transformer for continuous multimodal generation. During inference, text is generated through standard next-token autoregressive decoding, while non-text modalities, such as images, video, audio, and actions, are synthesized through iterative denoising. This unified architecture enables Cosmos3 to model heterogeneous modalities within a single framework while preserving generation mechanisms best suited to each modality.

-Raw data from internal and external sources is transformed into training-ready data through multiple stages of curation, filtering, and quality review. Data acquisition spans diverse multimodal sources — robotics, autonomous driving, industrial environments, indoor and outdoor scenes, varied lighting and weather conditions, camera viewpoints, object categories, and human activities — to broaden coverage across Physical AI operating environments. Automated filtering pipelines remove corrupted, duplicate, low-quality, and restricted content. Metadata analysis, heuristic rules, and model-assisted classifiers are applied during preprocessing to flag anomalous distributions and low-diversity subsets. Human review supplements automated filtering for selected datasets, benchmark construction, and targeted quality analysis. Datasets are balanced across modalities and task categories — visual reasoning, text-to-image, text-to-video, image-to-video, audio generation, video transfer, action-conditioned generation, and action command generation — to reduce overrepresentation of narrow domains. Synthetic and simulation-based augmentation supplements coverage of rare physical interactions and edge-case scenarios. Deduplication and provenance tracking are applied across the corpus. The resulting processed data is converted into model-ready tokenized or encoded representations through modality-specific preprocessors before training begins.
-
-Training datasets passed through multiple layers of automated and manual safeguards designed to reduce the presence of harmful or policy-violating content across categories including weapons and weapons-related instructional content, criminal planning, child sexual abuse material (CSAM), non-consensual intimate imagery (NCII), sexual content involving minors, harassment, hate speech, profanity, threats and incitement to violence, self-harm or suicide-related content, and graphic violence. Data sources are reviewed for licensing compatibility, provenance, and alignment with internal data governance and safety policies before admission into training corpora. Automated filtering pipelines combine multiple detection strategies: hash-matching against known CSAM and NCII reference databases; classifier-based moderation models trained for explicit sexual content, hate speech, violence, weapons imagery, and other restricted categories; keyword and regex-based screening for criminal-planning, threats, and self-harm phrases in text data; metadata and provenance heuristics for source-level risk signals; and embedding-based anomaly detection to surface samples that fall outside expected distributions. Human review and targeted audits supplement automated filtering for selected datasets, benchmark construction, and safety-sensitive evaluation. For multimodal Physical AI data (robotics, autonomous driving, industrial scenes), additional filtering targets invalid action trajectories, physically implausible interactions, and unsafe control sequences. Synthetic and simulation-generated data are evaluated through internal validation before inclusion. Benchmark evaluations and red-team testing are applied post-training to surface remaining safety gaps across world generation, reasoning, audio, and action tasks. No large-scale data-filtering process can guarantee complete removal of all harmful content; residual risks may remain, particularly in rare edge cases or open-world deployment settings. Ongoing monitoring and dataset review continue post-release.

-## Usage
-
-- See [Cosmos](https://github.com/nvidia/cosmos) for details.
-
-### Prompt upsampling
-
-For optimal quality, text prompts should be upsampled into a specific JSON structure. Description and code can be found [here](https://github.com/nvidia/cosmos-framework/blob/main/docs/prompt_upsampling.md).
-
-For example, for text-to-video upsampling using Opus-4.6:
-
-```bash
-git clone https://github.com/NVIDIA/cosmos-framework.git packages/cosmos-framework
-pip install -e packages/cosmos-framework
-
-export PROMPT_UPSAMPLER_ENDPOINT_URL="https://api.anthropic.com/v1/"
-export PROMPT_UPSAMPLER_MODEL_NAME="claude-opus-4-6"
-export PROMPT_UPSAMPLER_API_TOKEN="<you_token>"
-
-python -m cosmos_framework.inference.prompt_upsampling \
-    --input assets/example_t2v_prompt_short.txt \
-    --output /tmp/upsampled_t2v_opus/ \
-    --mode text2video \
-    --endpoint-url "${PROMPT_UPSAMPLER_ENDPOINT_URL}" \
-    --model "${PROMPT_UPSAMPLER_MODEL_NAME}" \
-    --api-token "${PROMPT_UPSAMPLER_API_TOKEN}" \
-    --resolution 720 \
-    --aspect-ratio "16,9"
-```
-
-The JSON-upsampled version of `assets/example_t2v_prompt_short.txt` is saved in `assets/example_t2v_prompt.json` for convenience, and is used for the video generation examples below.
-
-### vLLM-Omni
-
-#### Container
-
-```
-docker pull vllm/vllm-omni:cosmos3
-```
-
-#### General Invocation
-
-You can use the release-tested `vllm-omni` package for deploying an OpenAI-compatible API inference endpoint.
-The recommended vLLM-Omni serving configuration for nvidia/Cosmos3-Nano on H200 is:
-
-```bash
-vllm serve nvidia/Cosmos3-Nano \
-  --omni \
-  --host 0.0.0.0 \
-  --port 8000 \
-  --init-timeout 1800
-```
-
-To speed up inference with additional GPUs, enable context parallelism with `--ulysses-degree` or switch to tensor parallelism with `--tensor-parallel-size`. Setting `--enable-layerwise-offload` can help reduce memory usage on GPUs with less available memory.

-##### Action generation
-
-The forward-dynamics example uses AgiBotWorld-Beta robotics action trajectories, and the inverse-dynamics examples use autonomous-vehicle (AV) action trajectories. Source files:
-
-- Forward dynamics first frame: `assets/example_action_fd_agibotworld_first_frame.png`
-- Forward dynamics action chunks: `assets/example_action_fd_agibotworld_action_chunks.json`
-- Forward dynamics output video: `assets/example_action_fd_agibotworld_4chunk_output.mp4`
-- Inverse dynamics source videos: `assets/example_action_id_av_0_input.mp4`, `assets/example_action_id_av_1_input.mp4`
-- Inverse dynamics predicted actions: `assets/example_action_id_av_0_output.json`, `assets/example_action_id_av_1_output.json`
-
-###### Action forward dynamics
-
-The example below performs a 4-chunk AgiBotWorld-Beta robotics rollout with the vLLM-Omni `/v1/videos/sync` inference endpoint. Each request sends one conditioning frame through `input_reference` and one 16-step normalized 29-D action chunk through `extra_params["action"]`. The request also sets the top-level `size` field to the input image resolution, so vLLM-Omni returns each chunk at the same resolution as the conditioning image without reflection padding. The stitched output drops each chunk's conditioning frame, producing 64 generated frames. The script extracts the last generated frame from each chunk and uses it as the next chunk's conditioning frame.

-  --port 8000
-```
-
-#### Examples
-
-##### Reasoning
-
-Run this example from the model repository root. It reads the robot planning prompt from `assets/example_reasoning_prompt.json` and sends `assets/example_reasoning_input.png` to the local vLLM server.
-
-```python
-import json
-from pathlib import Path
-
-import openai
-
-# 1. Read the image reasoning prompt
-example = json.load(open("assets/example_reasoning_prompt.json"))
-image_path = Path("assets/example_reasoning_input.png").resolve()
-image_url = image_path.as_uri()
-
-# 2. Query the OpenAI-compatible vLLM server
-client = openai.OpenAI(
-    api_key="EMPTY",
-    base_url="http://localhost:8000/v1",
-)
-
-response = client.chat.completions.create(
-    model=client.models.list().data[0].id,
-    messages=[
-        {
-            "role": "user",
-            "content": [
-                {"type": "image_url", "image_url": {"url": image_url}},
-                {"type": "text", "text": example["prompt"]},
-            ],
-        },
-    ],
-    max_tokens=example["max_tokens"],
-    seed=0,
-)
-
-# 3. Print the generated reasoning output
-print(response.choices[0].message.content)
-```
-
-Example input:
-
-<img src="assets/example_reasoning_input.png" width="640">
-
-Prompt:
-
-```text
-The task is to put flower into the red bottle. Generate a plan consisting of subtasks for accomplish the task.
-```
-
-Example output from the command above:
-
-```text
-Move your arm to the flower. Grasp the flower. Move your arm to the red bottle. Place the flower in the red bottle.
-```
-
-### Diffusers
-
-Cosmos3 is fully supported within the popular HuggingFace Diffusers package. This integration makes it a supported inference backend, allowing developers to easily incorporate Cosmos3's capabilities — such as text-to-video generation — into their pipelines using the `Cosmos3OmniPipeline` class, as demonstrated by the provided code examples (see examples for other modalities on the HuggingFace Cosmos3 page).
-
-#### Container
-
-To install diffusers with Cosmos3OmniPipeline:
-
-```
-uv venv --python 3.13 --seed --managed-python
-source .venv/bin/activate
-uv pip install \
-  "diffusers @ git+https://github.com/huggingface/diffusers.git" \
-  accelerate \
-  av \
-  cosmos_guardrail \
-  huggingface_hub \
-  imageio \
-  imageio-ffmpeg \
-  torch \
-  torchvision \
-  transformers
-
-```
-
-#### Examples
-
-##### Text to video generation
-
-Run this example from the model repository root. It reads the JSON-upsampled prompt from `assets/example_t2v_prompt.json` and the negative prompt from `assets/negative_prompt.json`. It then loads the pipeline and generate the video, then save it to an MP4 file.
-
-```python
-import json
-import torch
-from diffusers import Cosmos3OmniPipeline
-from diffusers.schedulers.scheduling_unipc_multistep import UniPCMultistepScheduler
-from diffusers.utils import export_to_video
-
-# Read JSON-upsampled prompt and negative prompt
-json_prompt = json.load(open("assets/example_t2v_prompt.json"))
-negative_prompt = json.load(open("assets/negative_prompt.json"))
-
-pipe = Cosmos3OmniPipeline.from_pretrained(
-    "nvidia/Cosmos3-Nano",
-    torch_dtype=torch.bfloat16,
-    device_map="cuda",
-    enable_safety_checker=True,
-)
-pipe.scheduler = UniPCMultistepScheduler.from_config(pipe.scheduler.config, flow_shift=10.0)
-
-result = pipe(
-    prompt=json.dumps(json_prompt),
-    negative_prompt=json.dumps(negative_prompt),
-    num_frames=189,
-    height=720,
-    width=1280,
-    num_inference_steps=35,
-    guidance_scale=6.0,
-    generator=torch.Generator(device="cuda").manual_seed(123),
-)
-
-export_to_video(result.video, "/tmp/cosmos3_nano_t2v_diffusers.mp4", fps=24)
-print("Saved video to /tmp/cosmos3_nano_t2v_diffusers.mp4")
-```
-
-Example output:
-
-<video controls width="1280" height="720" src="https://huggingface.co/nvidia/Cosmos3-Nano/resolve/main/assets/example_t2v_diffusers_output.mp4"></video>
-
-### SGLang
-
-[SGLang Diffusion](https://docs.sglang.io/docs/sglang-diffusion/index) can serve `nvidia/Cosmos3-Nano` through OpenAI-compatible image and video generation endpoints. Install SGLang from the main branch with diffusion dependencies, then start a server:
-
-```shell
-git clone --branch main https://github.com/sgl-project/sglang.git
-cd sglang
-pip install -e "python[diffusion]"
-pip install "cosmos-guardrail==0.3.1"
-
-sglang serve --model-path nvidia/Cosmos3-Nano
-```
-
-Cosmos 3 support in SGLang Diffusion currently requires the SGLang main branch. Switch to a stable SGLang release once Cosmos 3 support is included there.
-
-For a video-specialized checkpoint, use `Cosmos3-Super-Image2Video` with multiple GPUs:
-
-```shell
-sglang serve \
-  --model-path nvidia/Cosmos3-Super-Image2Video \
-  --num-gpus 4
-```
-
-Supported SGLang endpoints:
-
-| Mode | Endpoint | Notes |
-| --- | --- | --- |
-| Text to image | `POST /v1/images/generations` | Returns base64 image data by default |
-| Text to video | `POST /v1/videos` | Creates an async job; poll `GET /v1/videos/{id}` and download `/content` |
-| Image to video | `POST /v1/videos` | Upload the conditioning image with `input_reference` |
-
-Example text-to-video request:
-
-```shell
-job_id=$(curl -sS -X POST http://localhost:30000/v1/videos \
-  --form-string "prompt=A small warehouse robot moves a blue box across a clean floor." \
-  --form-string "negative_prompt=blurry, distorted, low quality" \
-  --form-string "size=1280x720" \
-  --form-string "num_frames=81" \
-  --form-string "fps=24" \
-  --form-string "num_inference_steps=35" \
-  --form-string "guidance_scale=4.0" \
-  --form-string "flow_shift=10.0" \
-  --form-string "seed=42" \
-  --form-string 'extra_params={"guardrails":true,"use_resolution_template":false,"use_duration_template":false}' \
-  | python -c 'import json, sys; print(json.load(sys.stdin)["id"])')
-
-while true; do
-  status=$(curl -sS "http://localhost:30000/v1/videos/${job_id}" \
-    | python -c 'import json, sys; print(json.load(sys.stdin)["status"])')
-  [ "$status" = "completed" ] && break
-  [ "$status" = "failed" ] && exit 1
-  sleep 1
-done
-
-curl -sS -L "http://localhost:30000/v1/videos/${job_id}/content" \
-  -o cosmos3_t2v_output.mp4
-```
-
-SGLang accepts Cosmos 3 request options including `max_sequence_length`, `flow_shift`, `extra_params.guardrails`, `extra_params.use_resolution_template`, and `extra_params.use_duration_template`. Video-to-video, video-with-sound, and action generation are not supported by SGLang yet.
-
-For complete serving instructions and request examples, see the [Cosmos3 SGLang cookbook](https://docs.sglang.io/cookbook/diffusion/Cosmos/Cosmos3).
+Please see our [technical paper](https://huggingface.co/papers/2606.02800) for detailed evaluations of the model.
 
 ## Limitations
 
-Cosmos3 may produce imperfect outputs in challenging scenarios. Generation artifacts include temporal inconsistency, unstable camera or object motion, imprecise physical interactions, inaccurate audio-video synchronization, and action-state drift — especially in long-horizon or high-resolution outputs. Reasoning may also be incorrect: object states, causal relationships, spatial geometry, temporal ordering, agent intent, and future outcomes can be misinferred, and complex or long-context inputs may yield hallucinated entities, inconsistent interpretations, or implausible predictions. Because the model lacks an explicit physics simulator, 3D geometry, 4D space-time evolution, object permanence, contact dynamics, and physical laws are only approximated — producing artifacts such as disappearing or morphing objects, unrealistic collisions, and physically implausible motions. Quality further degrades in out-of-distribution environments, safety-critical edge cases, and domains underrepresented in training.
-
-Cosmos3 outputs should not be treated as physically accurate simulation, reliable ground-truth reasoning, or safety-certified decision making. Applications involving robotics control, autonomous systems, scientific simulation, or safety-critical planning require additional validation, external constraints, system-level safety analysis, and domain-specific guardrails before deployment.
+Cosmos3 may produce artifacts in long, high-resolution, or physically complex outputs. Common failure modes include temporal inconsistency, unstable camera or object motion, inaccurate sound-video alignment, imperfect action-state consistency, and physically implausible dynamics. It does not have an explicit physics engine and approximates physical laws.
