Imagen 4 is Google's latest text-to-image model, delivering photorealistic results with broad style support. Through RunAPI, every Imagen 4 variant shares one API key.
A single RunAPI API key unlocks the whole model catalog across all providers. No separate accounts to create, no API keys to rotate per integration, and no credential management overhead. Add a new model to your app by changing one parameter.
Per-call pricing in USD, billed monthly into a single invoice. No subscription tiers, no minimum spend, and failed generations are never charged. The pricing page and check_pricing API show exact costs before you commit to a model.
Typed schemas, parameter constraints, and setup notes are packaged in the model skill so your implementation starts from the right contract. The skill loads into Claude Code, Codex, Gemini CLI, Cursor, and VS Code — your agent knows the correct request shape before you write a line of code.
The Imagen 4 Pro remix image endpoint outputs 1K, 2K, or 4K; the text-to-image endpoint has no resolution parameter. The ultra variant pushes quality further for brand and marketing use.
Fast generates in ~2.7 seconds for drafts. Standard balances quality and cost. Ultra delivers maximum photorealism for final production assets.
Imagen 4 has strong typography support — it reliably renders short text like brand names, labels, and headlines within images.
It takes source images as style or content seeds and generates a new image guided by both the sources and your text prompt.
Not natively. For transparent backgrounds, generate the image and then use a background removal tool like Recraft.
Pick the cheapest variant that meets your quality bar. Most teams start on the fast variant and graduate to pro for production.
