profile

Weixian Xu

I am a third-year undergraduate at the ACM Honors Class, Shanghai Jiao Tong University, currently working as a research intern at GAIR Lab.

Research Interests

• Self-Evolving AI: Lifelong learning, memory retention, and continuous adaptation.
• Human-Centric AI: Realizing genuine partnership and emotional support through sustained memory and evolution.
• Model & Agent Architectures: Innovation spanning from individual neural structures to multi-agent collaborative frameworks.

Key Projects

• ASI-Arch: Autonomous neural architecture discovery system (1.1k+ Stars).
• ACore: Comprehensive OS kernel implementation (Rust).
• Imxc: High-performance compiler with advanced optimizations (Java).
• RISC-V CPU: Verilog implementation of Tomasulo architecture.

Background

My research is dedicated to the vision of Self-Evolving AI—transforming models from static tools into dynamic partners that grow alongside users.

What distinguishes my approach is my strong foundation in systems engineering. With extensive experience in building OS kernels, compilers, and hardware architectures, I possess the engineering capability to implement complex AI innovations from the ground up. I leverage this technical depth to advance research on two fronts: designing novel internal architectures for individual models to enhance their inherent capabilities, and engineering collaborative protocols for robust multi-agent ecosystems.
