Fal.ai Image Generation

Fal.ai is one of the most widely used API platforms for AI image generation, offering fast inference on top models including Flux Pro, Stable Diffusion, and more. To use this skill, create a free API key at fal.ai/dashboard/keys and add it to your .env as FAL_API_KEY.

Generate high-quality images via Fal.ai's API. The key is already in .env as FAL_API_KEY — the client needs it as FAL_KEY.

import fal_client, os
os.environ['FAL_KEY'] = os.environ['FAL_API_KEY']  # required alias

    arguments={
        'prompt': 'your prompt here',
        'image_size': 'square_hd',   # 1:1 for Instagram feed
        'num_images': 1,
