Kronos: A Foundation Model for Financial Markets — A Technical Deep Dive |  by Antonio Velazquez Bustamante | Aug, 2025 | Medium

In the wave of quantitative finance, a Python library named Kronos is quietly transforming how AI understands financial markets. It is not merely a tool, but the world's first foundational model specifically designed for financial K-line data, like a "prophet" capable of interpreting market language.

Kronos, introduced by the research team at Tsinghua University, is a unified, scalable pre-training framework specifically designed for financial market K-line data.

It discretizes continuous market information into a series of token sequences while preserving price dynamics and trading activity patterns.

The development of Kronos was inspired by large-scale pre-training paradigms (such as Large Language Models - LLMs), aiming to address the limitations of existing Time Series Foundation Models (TSFMs) in financial K-line data applications.
