Type a prompt, add reference images, and compare 1K, 2K, and 4K output in the browser. Use the free playground to check fit, then confirm API key, balance, pricing, and limits before production.
Run text-to-image, reference-image editing, and size tests without starting in the docs.
Free means you can open the playground and test the flow. Production API use still depends on account billing.
Use a low-cost model for prompt iteration, then move stable prompts to Pro, Nano Banana 2, or GPT Image 2 VIP.
Shown prices are planning estimates for testing. Check balance, pricing, model access, and limits before production.

Before production, verify API key status, balance, pricing, model availability, concurrency, and failure rules in the account page.
Nano Banana is the lowest-cost route shown here, so it is the first model to test for cheap online image generation and prompt iteration.
YingTu works as a free online playground for browser testing. Production API calls, credits, gifts, and limits depend on the current account and billing rules.
Use Nano Banana for low-cost drafts, Nano Banana Pro for text and 4K work, Nano Banana 2 for value-focused preview tests, and GPT Image 2 VIP for the OpenAI image route.
