vis logo

Vis is a from-the-ground-up coding agent inspired by Recursive Language Models (Zhang, Kraska & Khattab, 2025): instead of spending the context window on an ever-growing transcript, the model writes Python into a sandboxed GraalPy runtime, keeps state in named variables and SQLite, and treats context as an external environment it can inspect and change.

• Clojure CLI 1.12+
• Java 21+ (JDK 25 recommended)
