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.
SAVRN's Notes on ModernBERT-large
Nothing here generates text. Answer.AI built ModernBERT-large as an encoder, trained on 2 trillion tokens of English and code, and our reading is retrieval and classification over long documents, up to its 8,192-token context. Memory is the smallest line item in the rack: 1.0 GB at 16-bit, 0.2 GB at 4-bit, against a cheapest slot of one MI300X with 192 GB at $1.85 an hour, so it rides alongside a generation model rather than earning its own card.
The license is Apache 2.0: commercial use, modification and redistribution are allowed, notices stay, significant changes get stated, and contributors grant patents. Access is open. Check the disk footprint first, 16 files and 7.86 GB stored in float32, several times what loads into memory at 16-bit. It ships in safetensors, onnx and pytorch. The design paper is arXiv:2412.13663; read it for the local-global alternating attention behind the 8,192-token window.
SAVRN's Notes on xlm-roberta-large
Fitting this one is never the problem. At 16-bit the weights are 1.1 GB and the run needs 1.3 GB, so the cheapest setup on the page, one 192 GB MI300X at $1.85 an hour on-demand, has room for more than a hundred copies; put it on a GPU already serving something else. What the footprint buys is a fill-mask model trained on 2.5 TB of filtered CommonCrawl in 100 languages with a 250,002-entry vocabulary: a starting layer for multilingual text work you tune yourself, not a finished application.
MIT asks only that the copyright and permission notice travel with what you ship; commercial use, modification and redistribution are allowed. Note the 514-token context, sentences and short passages rather than documents, and the 17 files totaling 11.2 GB across five formats, of which your runtime needs one. The releasing team did not write the card; start from arXiv 1911.02116.
Questions
