Kronos is an open-source foundation model built specifically for financial K-lines — the open, high, low, close and volume behind every candle. Instead of reading a chart as an image, it turns market data into tokens and learns the sequence like a language model.

The 60-second version
It treats candles like words.
A specialised tokenizer converts continuous OHLCV market data into hierarchical discrete tokens. A decoder-only Transformer then learns the patterns between those tokens and generates possible future K-line sequences.
Reality check: this is a research model, not a magic signal generator. Forecasts are probabilistic, markets change regime, and a backtest is not a promise of future returns. Use it to research — not to outsource risk.

The official demo visualises a 24-hour BTC/USDT forecast. Start here if you want to see the output before installing anything.
The example loads a pretrained Kronos model, forecasts the next window and renders predicted candles against the ground truth.

The pretrained tokenizer and model are downloaded from Hugging Face on first use.
5 Bring your own market data
Feed KronosPredictor a pandas DataFrame with open, high, low and close. Volume and amount are optional. The repo also includes a full fine-tuning pipeline for adapting the tokenizer and predictor to your own domain.
