Recraft: Recraft V4.1 Utility

Recraft V4.1 Utility is a general-purpose image generation model from Recraft. It supports text and image inputs with image output at ~1K resolution across multiple aspect ratios, with typical generation around 10 seconds. The Utility line is designed for restraint as the aesthetic choice - flat lighting, front-facing composition, and simple, controlled scenes - making it a practical fit for product imagery, mockups, and structured visuals where the high-aesthetic V4.1 line would be too expressive.

V4.1 improvements over V4 include more natural object understanding, sharper mockups, cleaner default icons, and stronger prompt adherence with shorter prompts. Supports the following `image_config` parameters: `strength` (controls how much the output deviates from the source image), `rgb_colors` (sets a color palette), and `background_rgb_color` (sets the background color). See the image generation docs for details: https://openrouter.ai/docs/features/multimodal/image-generation

Note: only one input image is supported.
