- 🔧 This model is part of Sico — an open-source platform for building and evolving Digital Workers, where AI agents and their human operators co-evolve through real work.
- ⭐ Star the Sico repository to follow new evolved models and our model evolution pipeline — this GUI agent is the first public release, with more on the way.
- 📄 Backed by our survey on agentic evolution and co-evolving human–AI systems.
GELab-Zero-4B-preview-Sico-Evolution
A 4B GUI agent fine-tuned (LoRA) from the open-source GELab-Zero-4B-preview base model
on Microsoft Edge and Copilot UI trajectories. It is built with our general-purpose
GUI model evolution pipeline — an iterative mechanism that keeps lifting an agent's real
task success rate round after round, and transfers to any GUI app.

Highlights
From 39.8% to 82.9%: Sico-Evolution achieves a dominant 82.9% Task Success Rate, a massive +43.1% absolute surge over the 39.8% base-model baseline.
Outperforms Closed-Source SOTAs: It edges out top proprietary giants like gpt-5.4 (79.7%), Claude-Opus-4.6 (81.3%), and claude-opus-4.7 (82.1%).
Vastly Exceeds Open-Source Models: It crushes leading competitors including kimi-k2.6 (62.6%) and UI-Venus-1.5-30B (61.0%).
