MiniMax H3 Image Model: Fast and Realistic but Lacks Detail and Controls

Reddit users testing MiniMax H3 found it generates high-resolution, photorealistic images quickly (about 45 seconds in 6 steps on a 4070S), but criticized its lack of ControlNet-style reference controls, weaker editing performance, and missing details, with some calling the release rushed and buggy.
