NX-AI/TiRex

35M params | 512 context | $0.5000 input | $1.50 output

TiRex is NX-AI's xLSTM-based zero-shot forecasting model. The official card highlights strong short- and long-horizon performance, plus support for both point and quantile forecasts, without relying on a Transformer backbone. It is a good alternative when you want a compact non-Transformer forecaster with strong in-context generalization behavior.

Model Classification

Family

TiRex

Type

time series foundation model

Pretrained time-series model exposed on TSFM.ai for zero-shot or few-shot forecasting workloads.

Training Data

Official card lists autogluon/chronos_datasets and Salesforce/GiftEvalPretrain as the main sources, without publishing a more exact mixture breakdown.

Recommended For

  • Compact zero-shot forecasting when you want an alternative to Transformers
  • Short- and long-horizon forecasting with probabilistic outputs

Strengths

  • xLSTM backbone differentiates it from the dominant Transformer families
  • Competitive capacity-to-quality ratio

Limitations

  • Smaller ecosystem than the biggest public TSFM families
  • Less familiar operationally if your team only benchmarks Transformer-based models
