# Kronos

Kronos is the first open-source foundation model built for financial candlestick (K-line) sequences, pretrained on data from more than 45 global exchanges. General time-series foundation models are not designed for the high-noise character of financial data, so Kronos first quantizes continuous multi-dimensional K-lines such as open, high, low, close and volume into hierarchical discrete tokens, then pretrains an autoregressive Transformer on those tokens as one model for diverse quantitative tasks. The release includes pretrained weights of several sizes, fine-tuning scripts and a live demo forecasting BTC/USDT over the next 24 hours.
