Kronos Base is the largest checkpoint in the NeoQuasar Kronos family and the best choice for maximum forecast quality on financial time-series workloads. It uses the largest tokenizer vocabulary and deepest transformer stack in the family. Designed primarily for OHLCV candlestick data; the official examples require at least OHLC columns, with volume and amount optional.

Training Data

Official Kronos model cards describe pretraining on over 12B K-line records from 45 global exchanges.

Recommended For

• Financial time-series forecasting with OHLCV candlestick data
• Multi-asset price prediction across equities, forex, and crypto

Strengths

• Purpose-built tokenizer for financial price movement patterns
• Native OHLCV support with synthetic fallback for univariate series

Limitations

• Domain-specific to financial data — not a general-purpose TSFM
• Best fit when open, high, low, and close covariates are provided explicitly; the univariate fallback is a compatibility path, not the ideal contract
• Limited public documentation and benchmark coverage compared to major TSFM families
