Qwen-Image-2.1 experiments on Apple Silicon (M5 Max, MLX, bf16) with my custom MFLUX 1600×672 (2.39:1), fixed seed: 10 steps → ~26s 20 steps → ~44s 30 steps → ~61s 40 steps → ~79s 50 steps → ~97s ~1.78s per step + ~8s fixed (load, prompt encode, VAE decode) Peak memory: 31 GB Prompt: A city street bends upward at the horizon: the ground and its buildings curve up from street level and arc into the sky like a giant wave, one single continuous landscape where skyscrapers grow progressively more vertical until they tower overhead, the road itself rising and wrapping up into the clouds. Dream physics like a folded dream city: no mirror duplication, just one seamless city rolling from horizontal to vertical. Wet reflective asphalt, cool blue-grey palette with warm window lights, glass and steel towers, low clouds threading between the rising districts, slight lens distortion, IMAX 70mm film look, cinematic wide-angle, photorealistic, volumetric haze, epic impossible scale.
