$0/M input tokens$0/M output tokens$4.79/M tokens

Riverflow V2 Fast is the fastest variant of Sourceful's Riverflow 2.0 lineup, best for production deployments and latency-critical workflows.

The Riverflow 2.0 series represents SOTA performance on image generation and editing tasks, using an integrated reasoning model to boost reliability and tackle complex challenges.

Pricing is $0.02 per 1K output image and $0.04 per 2K output image. Does not support 4K image output.

Additional features:

Custom font rendering via font_inputs ($0.03/font, max 2)
Image enhancement via super_resolution_references ($0.20/reference, max 4)

See the image generation docs for details: https://openrouter.ai/docs/features/multimodal/image-generation

Note: Sourceful imposes a 4.5MB request size limit, therefore it is highly recommended to pass image URLs instead of Base64 data.

Sample code and API for Riverflow V2 Fast

OpenRouter normalizes requests and responses across providers for you.

OpenRouter supports image generation through models that have image in their output modalities. These models can create images from text prompts when you specify modalities: ["image", "text"] in your request. The generated images are returned as base64-encoded data URLs in the assistant message. Learn more about image generation.

In the examples below, the OpenRouter-specific headers are optional. Setting them allows your app to appear on the OpenRouter leaderboards.

Using third-party SDKs

For information about using third-party SDKs and frameworks with OpenRouter, please see our frameworks documentation.

See the Request docs for all possible fields, and Parameters for explanations of specific sampling parameters.
