Paul Gauthier

Open-source AI pair programming tool for the terminal with 42,000+ GitHub stars. Pioneered repository mapping, diff-based editing, and the Architect/Editor dual-model approach for LLM-assisted coding. Processes 15 billion tokens weekly and 88% of its own new code was written by itself.

Widely-cited LLM code editing benchmark suite testing 225 Exercism exercises across C++, Go, Java, JavaScript, Python, and Rust. Used industry-wide to evaluate and compare LLM coding capabilities.

Co-founded with Eric Brewer in 1996. Built the first commercial search engine based on distributed-memory parallel computation, powering Yahoo, AOL, and other major portals. Acquired by Yahoo in 2002.

As VP of Engineering, developed computer vision technology enabling smartphone users to build and decorate 3D augmented reality versions of their homes. Acquired by IKEA in 2021.

Developed a novel approach using tree-sitter AST parsing to create concise repository maps, giving LLMs better understanding of large codebases for more accurate code edits.

Pioneered separating code reasoning (architect) from code editing (editor) using two models in tandem, enabling reasoning models like o1 and DeepSeek R1 to direct faster editing models.

Founded philanthropic organization supporting children's education from birth through post-secondary in Cole Harbour, Nova Scotia.
