  - `model_id` string: Hugging Face model ID used for image generation.
  - `loras` string: A LoRA (Low-Rank Adaptation) model and its corresponding weight for image generation. Example: { "latent-consistency/lcm-lora-sdxl": 1.0, "nerijs/pixel-art-xl": 1.2}.
  - `strength` number: Degree of transformation applied to the reference image (0 to 1).
