Clusy

An agent-native notebook for ML and data science. You describe the experiment; the agent finds the data, writes the cells, and runs the compute. Most of the work is in the runtime: kernel management, state persistence, and re-running only the cells a change actually affects.

Standardises GNSS and IMU logs across RINEX, NMEA, UBX, and undocumented formats. A language model writes the parser, the backend runs it, validates the output, and feeds errors back until it converges. The code behind the IPIN 2024 paper.
