Researchers have developed SMARLI, a novel framework for layout-conditioned autoregressive text-to-image generation. This approach uses a structured masking strategy within the attention mechanism to effectively integrate spatial layout constraints with text and image tokens, preventing feature entanglement. Additionally, a Group Relative Policy Optimization (GRPO) scheme, adapted for a next-set-based paradigm and incorporating image quality and layout rewards, is employed to mitigate exposure bias and improve generation accuracy. Experiments show SMARLI enhances layout control while maintaining the efficiency of autoregressive models and can be transferred to standard next-token-based models. AI
