About Krea 3 Ultra

Krea 3 Ultra is the highest-quality mode of Krea's Krea 3 image editing model, announced October 20, 2026. Instead of one pass, it generates several candidates, reviews them against the prompt and references, and returns the best, always at 2K; a job can take several minutes. It needs at least one input image and does not support regional edits. It is called through the same Krea 3 API endpoint with thinking_mode ultra, on Max plans and above, at $0.26 per 2K image plus reference fees.
