How do I write a good image generation prompt?

Be specific about the subject, then add the setting, lighting, camera or art style, and mood. "A ceramic mug on a wooden table, morning window light, shallow depth of field" works better than "a nice mug".

What image sizes can I generate?

Pick a resolution (1K, 2K or 4K) and an aspect ratio. At 2K, 1:1 is 2048 × 2048 and 16:9 is 2720 × 1536. At 4K, 1:1 is 4096 × 4096 and 16:9 is 5472 × 3072.

Do I pay for a generation that fails?

No. If the model returns an error or the prompt is blocked, the credits go back to your balance automatically.
