New RL framework trains UI agents on live iOS apps, outperforming Gemini models

By PulseAugur Editorial · [1 sources] ·

Researchers have developed an online reinforcement learning framework for training UI navigation agents on live iOS applications. This system utilizes a planning agent and a UI grounding model, enhanced by an LLM-as-a-Judge for reward signals and a novel neighbor-conditioned value estimation method called GiGPPO. The framework significantly outperforms supervised fine-tuning and terminal-only RL baselines, demonstrating strong generalization to Android environments and competitive performance against models like Gemini 3.5 Flash and Gemini-3.1 Pro. AI

IMPACT This framework could enable more robust and cost-effective AI agents for mobile application interaction.
