Researchers have developed BiGrounder, a novel approach to GUI grounding that maps natural language instructions to precise operational coordinates for autonomous agents. Unlike previous methods that relied solely on final coordinate supervision, BiGrounder employs a bidirectional training paradigm. This method equips the model to generate action descriptions from target coordinates during supervised fine-tuning (SFT) and then grounds these descriptions back to their targets during reinforcement learning (RL). A cycle-consistency gate ensures semantic quality is linked to grounding success, creating a self-reinforcing training loop. A 4-billion parameter model utilizing this technique demonstrated competitive accuracy across five grounding benchmarks. AI
