Is api_key necessary in option 1?

If you want to generate images only based on a text prompt, you should follow Option 1 and provide an api_key. This is because the layout is generated from GPT-4 using an api_key, which is used to guide the L2I models during generation. If you don't have an api_key, you can consider setting up the layout to meet the format in Option2.
