Text-to-image (T2I) generation has captivated the AI/ML world, evolving rapidly from rudimentary image synthesis to highly controllable and context-aware creation. Yet, this field grapples with critical challenges: achieving precise control over generated content, enhancing efficiency, ensuring safety and fairness, and deeply embedding real-world knowledge. Recent research breakthroughs are pushing the boundaries, tackling these issues head-on and paving the way for more intelligent and versatile generative AI.### The Big Idea(s) & Core Innovationscurrent wave of innovation in T2I generation centers around three major themes: enhanced control and alignment, boosting efficiency, and integrating deeper intelligence and safety. Researchers are developing ingenious ways to guide models, refine outputs, and make them more robust.*enhanced control and alignment, several papers offer novel strategies:Decoupling generation for precision: Researchers from Zhejiang University, in their paper “3DIS: Depth-Driven Decoupled Instance Synthesis for Text-to-Image Generation“, introduce a framework that separates multi-instance generation into coarse depth map creation and fine-grained detail rendering. This significantly improves layout precision and attribute rendering without additional training. Similarly, Qualcomm AI Research’s “Ar2Can: An Architect and an Artist Leveraging a Canvas for Multi-Human Generation” disentangles spatial planning from identity rendering in multi-human generation, effectively preventing issues like face duplication.Intelligent prompting and guidance: Seoul National University researchers, in “Guiding What Not to Generate: Automated Negative Prompting for Text-Image Alignment“, propose NPC, an automated pipeline that leverages both targeted and ‘untargeted’ negative prompts to improve text-image alignment.
