Every generation, your way.

Shape, size and model — three choices that cover everything from a quick blog thumbnail to a full-bleed hero image.

  1. Aspect ratios

    Pick the right shape

    1:1 for square thumbnails, 16:9 for landscape heroes, 9:16 for portrait and social formats, or 4:5 for feed-optimized visuals. The model generates at the correct dimensions every time.

  2. Resolution tiers

    1K, 2K or 4K

    Match resolution to the job. 1K is fast and lightweight for most content images. 2K and 4K deliver sharper output for hero sections, large feature images, or anywhere pixel density matters.

  3. Flash model

    Fast iterations, lower cost

    Flash is built for speed. Use it when you're exploring ideas, need a quick placeholder, or want to try multiple prompts before committing. Faster results, fewer credits.

  4. Pro model

    Higher fidelity output

    Pro produces more detailed, accurate images — better prompt adherence, sharper style matching and cleaner results overall. Use it when the image is going straight into a published page.

AI agent

Or just ask the content agent.

Image generation is part of any task, not a separate step. Ask for a post and its cover image in one message — the agent writes the prompt, matches your existing visual style, saves the file where Astro wants it and links it into the right field. You just review.

One message
"Write the offsite recap and generate a cover image to match." One request, both delivered — in order, without opening the image generator.
Style-aware
Point it at images already on your site and it uses them as references automatically. No manual selection, no prompt engineering.
