Is Yug-1 state of the art?Pending benchmarks.Announced Oct 17, 2026; no independent results yet.
Birla AI Labs' first time-series foundation model: a 271.8M-parameter model for zero-shot probabilistic forecasting that returns a range of likely values (quantiles) rather than a single number, with or without covariates. Weights on Hugging Face under CC-BY-NC 4.0, which allows non-commercial use only. Not an LLM.

What would let us call it
Verdicts use only independent boards we already track. Two consecutive snapshots are required before any crown.
- Publicly announced with a source
- Usable by the public (API or weights)
- Listed on an independent board we track
- Enough results for a rank in a category
- Holds across two snapshots (crowns only)
What the lab claims
Self-reported. Shown for context; not used in any verdict.
Lab claim: forecasts outcomes, finds patterns and detects anomalies across complex, interconnected variables.
Lab claim: MASE 0.744 and CRPS 0.529 on GIFT-Eval (self-reported on the model card), ahead of other first-generation time-series foundation models.
