Testing OpenAI: Why GPT Imagine 1.5 Disappointed Us

OpenAI has released GPT Imagine 1.5. Is it a real step forward or just a cosmetic update of the old model? We tested it across different scenarios — from panda ninjas to John Wick. Spoiler: Nano Banana 2 Pro still looks more convincing, while OpenAI continues to struggle with fingers, complex objects, and anatomical details. We analyze whether the rendering has truly improved, where the yellow-green color cast went, and whether this update is worth paying for — or if it makes more sense to stick with proven generators.
