Prompts

prompts

Required

One text prompt per image you want to generate. Each prompt can be combined with the 'Images per prompt' setting to create multiple variations.

Type:array

Example:

[
  "A cyberpunk city street at night, neon reflections on wet pavement"
]

Image model

model

Optional

Which OpenRouter image-generation model to use. Defaults to Gemini 2.5 Flash Image (reliable, handles terse prompts well). Use 'Custom model ID' below to use any other OpenRouter model.

Type:string

Default:google/gemini-2.5-flash-image

Options:

google/gemini-3-pro-imagegoogle/gemini-3-pro-image-previewgoogle/gemini-3.1-flash-imagegoogle/gemini-3.1-flash-image-previewopenai/gpt-5.4-image-2openai/gpt-5-imageopenai/gpt-5-image-minigoogle/gemini-2.5-flash-imagegoogle/gemini-3.1-flash-lite-image

System prompt (optional)

systemPrompt

Optional

Optional extra instructions applied to every image (e.g. a consistent style, brand, or quality directive). This is appended to the built-in instruction that forces the model to always render an image and never reply with text.

Type:string

Custom model ID (advanced)

customModelId

Optional

Optional. Any OpenRouter model ID with image output, e.g. 'google/gemini-2.5-flash-image'. Overrides the 'Image model' selection above. See https://openrouter.ai/models?fmt=cards&output_modalities=image.

Type:string

Aspect ratio

aspectRatio

Optional

Aspect ratio of the generated images. Support varies by model; ignored by models that do not accept it.

Type:string

Default:1:1

Options:

1:116:99:164:33:43:22:321:9

Image resolution

imageSize

Optional

Output resolution. Higher resolutions cost more OpenRouter credit. Support varies by model.

Type:string

Default:1K

Options:

0.5K1K2K4K

Images per prompt

imagesPerPrompt

Optional

How many image variations to generate for each prompt (1-10).

Type:integer

Minimum:1

Maximum:10

Default:1

Concurrency

concurrency

Optional

How many images to generate in parallel. Higher is faster, but the built-in AI access starts refusing connections above about 6, which shows up as failed prompts rather than as speed. Raise it only when you supply your own OpenRouter API key (1-20).

Type:integer

Minimum:1

Maximum:20

Default:4

Max images (optional cap)

maxItems

Optional

Optional hard cap on the total number of images generated in this run, useful for controlling spend. Leave empty to generate one image for every prompt × images-per-prompt.

Type:integer

Minimum:1

OpenRouter API key (optional)

openRouterApiKey

Optional

Optional. Bring your own OpenRouter API key to call OpenRouter directly and bill your own OpenRouter account. Leave empty to use the built-in apify/openrouter proxy (billed as Apify credit, no key needed).

Type:string

OpenRouter proxy base URL (advanced)

proxyBaseUrl

Optional

Advanced. Override the API base URL. Leave empty to use the default (apify/openrouter proxy, or https://openrouter.ai/api/v1 when an OpenRouter API key is provided).

Type:string
