StepFun Open-Sources GELab-Zero 4B: The Lightweight GUI Agent That Conquers All Android Devices with Zero-Shot Automation Magic
StepFun AI launched GELab-Zero on November 28, 2025 — a fully open-source 4B-parameter multimodal GUI agent model designed for autonomous Android control, now available on Hugging Face under Apache 2.0. Featuring plug-and-play infrastructure for ADB handling, task recording, and local inference on consumer hardware (as low as 16GB VRAM), it achieves 75.86% success on AndroidWorld benchmarks for complex tasks like ride-hailing and shopping. This zero-dependency beast runs offline on any Android device, slashing latency while preserving privacy — a direct challenge to cloud-heavy agents like Claude's Computer Use, empowering devs to automate mobile workflows without vendor lock-in.
