DALL·E 3 API playground
This playground calls the OpenAI Images API straight from your browser using your own API key, so you can test DALL·E 3 prompts and parameters without writing any code. Set the size, quality, and style, watch the cost estimate update live, then generate — the image and OpenAI’s revised prompt appear inline.
How it works
When you click generate, the tool sends a single HTTPS request directly to
https://api.openai.com/v1/images/generations with your prompt and options. The
key travels only in that request’s Authorization header; there is no server in
between. DALL·E 3 returns an image URL plus a revised_prompt — the version it
actually rendered after its automatic rewriting — which the playground shows so
you understand the output.
Tips and notes
- Keep your key private. Paste it on your own machine; never share a screen recording that exposes the field.
- Watch the cost line. HD quality and 1792-pixel sizes are noticeably more expensive than standard 1024×1024 — the estimate updates as you change options.
- Read the revised prompt. If results drift from your intent, the revised prompt usually reveals why DALL·E reinterpreted a phrase.
- Use vivid vs natural deliberately. “Vivid” pushes dramatic, hyper-real looks; “natural” stays closer to a literal rendering.
