DataMind develops open-source LLM-based data analysis agents from multiple perspectives, including empirical diagnosis, generalist agent scaling, process-level supervision, long-horizon evaluation, and unsupervised skill discovery. Together, these works provide a systematic path toward more capable, scalable, and reliable data-analytic agents.
