Module: SmartPrompt::SiliconFlow::Image

Included in:
SmartPrompt::SiliconFlowAdapter
Defined in:
lib/smart_prompt/adapters/siliconflow/image.rb

Overview

Text-to-image (Kolors) + image editing (Qwen-Image-Edit). save_image comes from the ImagePersistence concern.

Constant Summary collapse

DEFAULT_IMAGE_SIZE =

Default resolution for text-to-image (Kolors accepts these "WxH" values).

"1024x1024".freeze

Instance Method Details

#edit_image(prompt, params = {}) ⇒ Object

Image editing / image-to-image (Qwen/Qwen-Image-Edit-2509 and Kolors composable). image (and optionally +image2+/+image3+) may be a local file path, a base64 data URL, or a public http(s) URL. Edit models reject image_size, so we omit it.

#generate_image(prompt, params = {}) ⇒ Object

Text-to-image. SiliconFlow response is images.url (not OpenAI's data), and uses its own param names (image_size, batch_size, guidance_scale, ...). Returns an Array of b64_json:, seed:.
