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 bge-small-zh-v1.5
Twenty-four million parameters is a rounding error next to a 192 GB accelerator. bge-small-zh-v1.5 turns Chinese text into dense vectors for retrieval, clustering, classification and semantic search. At 16-bit it needs 0.1 GB, and at 8-bit or 4-bit the figure rounds to zero, so the cheapest Index listing, one MI300X at $1.85 an hour, is the floor of the price board, not a requirement of this model; it runs on whatever memory the model it serves leaves free.
Fine-tuning on a private corpus is the usual path for an embedding model, and MIT allows it: commercial use, modification and redistribution, with the copyright and permission notices kept. Two checks first: the 512-token window against your document lengths, since longer documents get split before embedding, and the two papers it traces to, arXiv:2309.07597 on C-Pack and arXiv:2310.07554 on retrieval augmentation. The weights have not moved since October 2023.
SAVRN's Notes on jina-embeddings-v2-small-en
Turning English text into vectors is the whole job here, and the 8,192 token window lets a full contract or filing go in as one piece. It is 33 million parameters in four layers, stored in float32, about 523 MB on disk. At 16-bit it needs 0.1 GB of memory, so the cheapest Index setup, one MI300X at $1.85 an hour, is far more card than the job calls for; in practice it shares a GPU with a generator, and the publisher also ships ONNX and CoreML builds.
Apache 2.0 permits commercial use, modification and redistribution, provided you keep the license and NOTICE files and state significant changes, and access is open. Before committing, confirm an English-only model fits your corpus, and read the ALiBi paper listed against it for how the 8,192 length is reached. The training relations name the C4 backbone and the publisher's negation dataset.
