A Reddit user ran the same demanding long prompt (K-pop-style woman picking flowers, with bokeh, film grain, finger detail and bottom text rendering) through 7 image models. Ranking: 1. Nano Banana 2.1, 2. GPT Image 2.5, 3. Muse Image, 4. Qwen Image 2.1 Turbo, 5. Flux 3 Klein (best open-weight so far), 6. Krea 2 Turbo, 7. Moss-Image-SFT (8-step LoRA). The sample shows Nano Banana 2.1 producing near-photographic results, while Qwen Image 2.1 and Moss-Image-SFT failed to render the model-name text correctly — closed SOTA still clearly ahead of open weights.
