Abstract: Multimodal Large Language Models (MLLMs) have powered Graphical User
Interface (GUI) Agents, showing promise in automating tasks on computing
devices. Recent works have begun exploring reasoning in GUI tasks with
encouraging results. However, many current approaches rely on manually designed
reasoning templates, which may result in reasoning that is not sufficiently
robust and adaptive for complex GUI environments. Meanwhile, some existing
agents continue to operate as Reactive Actors, relying primarily on implicit
reasoning that may lack sufficient depth for GUI tasks demanding planning and
error recovery. We argue that advancing these agents requires a shift from
reactive acting towards acting based on deliberate reasoning. To facilitate
this transformation, we introduce InfiGUI-R1, an MLLM-based GUI agent developed
through our Actor2Reasoner framework, a reasoning-centric, two-stage training
approach designed to progressively evolve agents from Reactive Actors to
Deliberative Reasoners. The first stage, Reasoning Injection, focuses on
establishing a basic reasoner. We employ Spatial Reasoning Distillation to
transfer cross-modal spatial reasoning capabilities from teacher models to
MLLMs through trajectories with explicit reasoning steps, enabling models to
integrate GUI visual-spatial information with logical reasoning before action
generation. The second stage, Deliberation Enhancement, refines the basic
reasoner into a deliberative one using Reinforcement Learning. This stage
introduces two approaches: Sub-goal Guidance, which rewards models for
generating accurate intermediate sub-goals, and Error Recovery Scenario
Construction, which creates failure-and-recovery training scenarios from
identified prone-to-error steps. Experimental results show InfiGUI-R1 achieves
strong performance in GUI grounding and trajectory tasks. Resources at
