An evaluation row appears only where at least two of these models report the same benchmark with the same stated configuration, metric, unit and setup. Different evaluators stay named in each cell. Values are shown as reported: no unit conversion, no ranking.
Other Reported Results
These results are listed for each model on its own, because the conditions needed to compare them are not stated or do not match. Two results that leave a condition blank are not assumed to share it.

SAVRN's Notes on chronos-2
Forecasting is the job here, not text. Chronos-2 takes one series or several related ones with covariates and returns multi-step quantile forecasts without training on your data first. At 119 million parameters it needs 0.3 GB at 16-bit, 0.2 GB of it weights, so the cheapest setup in our figures, a 192 GB MI300X at $1.85 per hour, answers the wrong question. It rides beside whatever else is on the accelerator; 8-bit or 4-bit saves two tenths of a gigabyte.
Apache 2.0 covers commercial use, modification and redistribution, with the license and NOTICE file kept and significant changes stated. Check lineage: it was trained on autogluon/chronos_datasets and Salesforce/GiftEvalPretrain, so keep your evaluation series out of both. No context length is listed and the Index carries no host price, so the running cost is your accelerator time; arXiv:2403.07815 and arXiv:2510.15821 set out the design.
Questions
