Nvidia Cosmos 3 Super Text-to-Image API

nvidia/cosmos-3-super/text-to-image
Text-to-image

Cosmos3 is a collection of Omnimodal world models capable of generating dynamic, high-quality video, image, audio, and action commands from combinations of text, image, video, and action trajectory inputs.

NVIDIA Cosmos 3 Super Text-to-Image

NVIDIA Cosmos 3 Super Text-to-Image is NVIDIA's flagship text-to-image model built on the Cosmos 3 architecture. Designed for high-fidelity physical world simulation, it delivers photorealistic images with strong prompt adherence, precise spatial reasoning, and support for negative prompting — making it well suited for both creative and technical generation tasks.

🌟 Key Features

🎨 Photorealistic Generation

Produces high-quality images grounded in physical realism, excelling at scenes with natural lighting, accurate materials, and spatial coherence.

📝 Strong Prompt Fidelity

Understands complex, multi-element prompts and accurately reflects subject, environment, style, and compositional instructions in the output.

🚫 Negative Prompting

Accepts a negative_prompt to explicitly exclude unwanted content, artifacts, or styles from the generated image.

📐 Flexible Output Sizes

Choose from six standard presets covering square, portrait, and landscape orientations to match any platform or use case.

🔁 Reproducible Results

Pin a seed value to reproduce or iterate on a specific generation, enabling systematic prompt refinement workflows.

⚙️ Parameters

ParameterRequiredDescription
promptText description of the image to generate. Maximum 2,500 characters.
negative_promptContent to exclude from the output (default: empty).
image_sizeOutput size preset: square_hd, square, portrait_4_3, portrait_16_9, landscape_4_3, landscape_16_9 (default).
num_inference_stepsDenoising steps (1–100, default: 28). Higher values improve quality but increase time.
guidance_scalePrompt adherence strength (1.0–20.0, default: 4.0). Higher values follow the prompt more strictly.
output_formatOutput format: jpeg (default) or png.
seedRandom seed for reproducibility. Omit for random results.

💡 Prompt Tips

A photorealistic close-up of hands shaping clay on a pottery wheel, warm studio lighting, shallow depth of field, 8K resolution.

  • Describe subject, environment, lighting, and camera perspective in a single coherent prompt.
  • Use negative_prompt to remove common artifacts: blurry, low quality, distorted, watermark, cartoon.
  • Keep guidance_scale between 3–5 for natural-looking outputs; increase to 7–10 for strict prompt adherence.
  • Use landscape_16_9 for cinematic or widescreen compositions.
  • Fix seed when iterating on prompt wording to isolate the effect of each change.

🎯 Use Cases

  • Creative Illustration — Generate concept art, characters, and environments from descriptive text prompts.
  • Product Visualization — Produce photorealistic product renders and lifestyle imagery from written descriptions.
  • Scene Prototyping — Rapidly visualize environment and set designs before committing to production.
  • Social Media Content — Create scroll-stopping visuals in any aspect ratio for any platform.
  • Research & Simulation — Leverage Cosmos's physical world grounding for technically accurate scene generation.
  • Rapid Iteration — Generate multiple candidates with varied seeds and prompts to explore creative directions quickly.

📝 Notes

  • prompt is the only required field (besides model).
  • output_format supports jpeg (smaller file size) and png (lossless).
  • Task status values: created, processing, completed, failed.
  • Generated image URLs are returned in outputs once status is completed.
