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 t5-base
Half a gigabyte of accelerator memory covers t5-base at 16-bit, with the weights at 0.4 GB, so the hardware question is not which card but how many jobs you stack on one. The cheapest setup in our data, a single MI300X with 192 GB at $1.85 per hour on-demand, sits nearly idle if this 223M-parameter translation model runs alone, so put it on a GPU already carrying other work.
Check two things first. Our record lists no context length, so test your longest translation inputs against the checkpoint directly. The 11 files total 4.5 GB across five formats; pull only the one your stack loads. Apache 2.0 permits commercial use, modification and redistribution as long as the license notices and any NOTICE file stay intact and you state significant changes, plus a patent grant from contributors. Pretraining was on C4; last update February 14, 2024.
Questions
