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-en-v1.5
Twelve layers and 33M parameters come to 0.1 GB at 16-bit, with weights that round to zero at 8-bit and 4-bit, and that settles the hardware question. This embedder turns documents and queries into vectors for the retrieval-augmented LLM work its publisher focuses on, and it never justifies its own card: one MI300X, 192 GB, $1.85 an hour on demand is the cheapest setup we price, and this model would take a fraction of a percent. Put it on the GPU your generator already occupies.
MIT asks for one thing, that the copyright and permission notices stay attached to the weights, and allows commercial use, modification and redistribution in return. Hold the 512-token context and the en in the name up against your corpus; the publisher points to bge-m3 for more languages and inputs up to 8192 tokens. The files have not changed since 2024-02-22.
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.
Questions
Which is larger, bge-small-en-v1.5 or bge-small-zh-v1.5?
