fal

FalImageModel conforms to ImageModel, so it works with generateImage.

let result = try await generateImage(
  model: FalImageModel("fal-ai/bytedance/seedream/v4.5/text-to-image"),
  prompt: "A tiny observatory on a snowy mountain",
  aspectRatio: "16:9"
)

The model reads FAL_API_KEY, falling back to FAL_KEY, and uses https://fal.run by default. Pass any fal image model ID as the first initializer argument.

n, size, aspectRatio, and seed map to fal request fields. Additional fal fields go under the fal provider key:

providerOptions: ["fal": ["num_inference_steps": 4]]

Current image examples include:

fal's catalog is dynamic. Copy the endpoint ID from the live fal model gallery; FalImageModel accepts any image endpoint with the standard fal response shape.
