Model API

Cosmos 3 Super Image

Cosmos 3 Super from NVIDIA creates detailed images from text prompts, with optional prompt expansion and an agentic mode that refines the result over several passes.

Run it

Quote the input, start the generation with the quote, then poll the job. Set RAYWAKE_API_KEY first; see Authentication.

# 1. Price the exact input (quotes are valid for up to 10 minutes)
curl -s https://api.raywake.com/v1/quotes \
  -H "Authorization: Bearer $RAYWAKE_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
  "model": "nvidia/cosmos-3-super/text-to-image",
  "input": {
    "prompt": "A red ceramic cup on a wooden table, soft morning light"
  }
}'

# 2. Start the generation with the quote_id from step 1
curl -s https://api.raywake.com/v1/generate \
  -H "Authorization: Bearer $RAYWAKE_API_KEY" \
  -H "Content-Type: application/json" \
  -H "Idempotency-Key: $(uuidgen)" \
  -d '{"model": "nvidia/cosmos-3-super/text-to-image", "quote_id": "QUOTE_ID", "input": {"prompt":"A red ceramic cup on a wooden table, soft morning light"}}'

# 3. Poll until the status is terminal

Input

Input fields for nvidia/cosmos-3-super/text-to-image
NameTypeDescription
promptrequiredstring
Text prompt describing the image to generate.
negative_promptstring
Content to steer the generation away from (colors, objects, artifacts).
enable_prompt_expansionboolean
Expand the prompt with OpenRouter before image generation. When enabled, the prompt is rewritten into the dense structured-JSON format Cosmos3 was trained on; generation falls back to the raw prompt if expansion fails.

Default: false

enable_agentic_generationboolean
Automatically generate and compare multiple candidate images, then refine the prompt between rounds to better match the original request. This can improve prompt adherence but increases latency and billable image generations.

Default: false

agentic_max_iterationsnumber (enum)
Maximum number of refinement rounds when agentic generation is enabled.

Default: 2

One of: 2

agentic_samples_per_iterationnumber (enum)
Candidate images to generate and judge per agentic iteration. The best candidate advances to the next rewrite stage.

Default: 2

One of: 2

agentic_early_stopboolean
Stop early when a candidate image is already a strong match for the prompt.

Default: true

image_sizestring (enum)
The size of the generated image. Each edge is clamped to 512-1280px (multiples of 16).

Default: square_hd

One of: square_hd, square, portrait_4_3, portrait_16_9, landscape_4_3, landscape_16_9

num_inference_stepsnumber (enum)
Number of denoising steps. More steps yield higher quality but take longer.

Default: 28

One of: 28

guidance_scalenumber
Classifier-free guidance scale. Higher values increase prompt adherence at the cost of diversity.

Default: 4

num_imagesinteger
The number of images to generate.

Default: 1

seedinteger
The same seed and prompt given to the same model version will produce the same image every time.
sync_modeboolean
If `True`, the image is returned as a data URI and the output data won't be available in the request history.

Default: false

output_formatstring (enum)
The format of the generated image.

Default: jpeg

One of: jpeg, png
