Which image generation models does Kyma support?
Kyma serves the leading image models through one API — FLUX.2 Pro and FLUX.1 Kontext from Black Forest Labs, Ideogram V3 for typography, the Recraft V4 family including vector output, Google's Imagen 4 and Nano Banana, and MiniMax Image. Switch between them by changing the model string.
How much does image generation cost?
You pay per generated image, with rates starting around half a cent. There is no subscription — you only pay for successful renders, and failed jobs are refunded in full. See the pricing page for per-model rates.
Is the image API OpenAI-compatible?
Yes. Call POST /v1/images/generations with your Kyma API key, the same shape as the OpenAI Images API. Generation is asynchronous: you receive a job id and poll GET /v1/jobs/{id} until it succeeds.
Can I generate logos and vector art?
Yes — Recraft V4 Vector outputs true SVG vector art, and Ideogram V3 excels at text and typography in images. Both are available on the same Kyma key as the photorealistic models.
