Kronos Small

Kronos Small is the mid-size checkpoint in the NeoQuasar Kronos family, sitting between the lightweight Mini variant and the higher-capacity Base model. It is the natural step up when Kronos Mini leaves accuracy on the table but the full Base checkpoint is more than a workload needs.

It uses a larger tokenizer vocabulary and more transformer capacity than the Mini variant, which is what improves accuracy on complex multi-asset financial forecasting tasks while keeping the same overall design — a GPT-style decoder over tokens produced by the family's financial candlestick tokenizer. Like the rest of the family it is designed for OHLCV candlestick data; the official examples require at least OHLC columns, with volume and amount remaining optional. The official Kronos model cards describe pretraining on over 12B K-line records from 45 global exchanges.

On TSFM.ai reach for Kronos Small as the balanced option for financial candlestick forecasting: stronger than Kronos Mini on complex multi-asset tasks, cheaper than Kronos Base. Drop to Mini when serving cost or throughput dominates, or step up to Base when maximum forecast quality is the priority.
