Related data seen ILI (CDC influenza-like illness, national) · related dataset CDC FluView ILINet (LOTSA) was used (via GIFT-Eval Pretrain (GiftEvalPretrain))

Evidence (5)
“The public portion (45% GIFT-Eval Pretrain) is drawn from the Toto 1.0 mix of GIFT-Eval Pretrain and the Chronos pretraining corpus, and is non-leaking with respect to the GIFT-Eval test split.”

Notes

Benchmark-only checkpoint: Toto 2.0 2.5B finetuned 10,000 steps on GIFT-Eval Pretrain (45%), Datadog metrics (30%), GIFT-Eval train split (15%) and TempoPFN synthetic (10%). It is a finetuned (not zero-shot) GIFT-Eval submission. The companion Toto-2.0-Family-and-Friends is an XGBoost-gated ensemble of 10 foundation models (not a separately pretrained model) and is not listed as a model here.
