StepFun's GELab-Zero Brings Powerful AI to Your Devices
StepFun Democratizes AI with New Open-Source Tool
In a move that could change how we interact with artificial intelligence, StepFun has launched GELab-Zero, its first completely open-source graphical user interface agent. This isn't just another cloud-based solution - it's designed to run right on your own devices, bringing powerful AI capabilities while keeping your data private.

Lightweight Powerhouse
What sets GELab-Zero apart is its ability to pack serious AI power into modest hardware. The 4B-scale model can operate smoothly on everyday computers and smartphones, responding quickly without needing an internet connection. "We wanted to create something that wouldn't just sit in research papers," explains a StepFun engineer. "This brings real AI capabilities to people's actual devices."
The setup process couldn't be simpler. Forget complicated installations - GELab-Zero offers true one-click operation that automatically handles all the technical dependencies behind the scenes.
Flexibility Where It Counts
For users managing multiple devices, GELab-Zero shines with its multi-device task distribution. Imagine coordinating tasks across several phones simultaneously while recording every interaction for later review. The system supports three distinct working modes:
- ReAct mode for responsive, immediate actions
- Multi-Agent mode for complex operations
- Scheduled tasks for automation
Early benchmark tests show impressive results in GUI understanding and interaction tasks. In real-world mobile scenarios particularly, GELab-Zero demonstrates why local AI might be the next big leap forward.
The project is already available on GitHub, inviting developers worldwide to explore and contribute.
Key Points:
- Local power: Runs 4B model directly on consumer devices
- Easy setup: One-click installation skips technical headaches
- Multi-device magic: Coordinate tasks across several phones effortlessly
- Proven performance: Excels in GUI understanding and real-world applications
