## Runs On

What it takes to serve bge-small-en-v1.5 (33M parameters): the memory its weights need at each precision, and the cheapest way to rent enough data-center GPUs to hold them.

| Precision | Weights | Memory needed | Cheapest setup | Per hour | Also fits |
| --- | --- | --- | --- | --- | --- |
| 16-bit | 0.1 GB | 0.1 GB | 1x [MI300X](https://savrn.com/ai-index/pricing/gpus/mi300x) (192 GB) Vultr | $1.85 | [1x H100](https://savrn.com/ai-index/pricing/gpus/h100) $1.99 · [1x MI325X](https://savrn.com/ai-index/pricing/gpus/mi325x) $2.00 |

Memory is the weights at that precision plus 20% for the runtime and a short context; a long context needs more. Prices are the lowest on-demand hourly rates in the [SAVRN Index](https://savrn.com/ai-index/pricing/gpus), read Oct 25, 2026.

## SAVRN's Notes on bge-small-en-v1.5

33M parameters, 0.1 GB at 16-bit, weights that round to zero at 8-bit and 4-bit, and 63.4M downloads a month — the most-pulled model in this part of the directory, ahead of every base and large neighbor. It turns documents and queries into vectors for retrieval work inside a 512-token context, and the cheapest setup we price, one 192 GB MI300X at $1.85 an hour, is occupied a fraction of a percent by it. This model rides on the GPU your generator already rents.

MIT permits commercial use, modification and redistribution, provided the copyright and permission notices stay attached. The 14 files total 401.1 MB because the repository carries bin, ONNX and safetensors copies of the same 12-layer weights stored in float32 — convert once and keep one. Nothing has changed since 2024-02-22, and the publisher itself points longer-context and multilingual users at bge-m3. Treat this as the small, fast, English-only default.

## Questions About bge-small-en-v1.5

### How much GPU memory does bge-small-en-v1.5 need?

About 0.1 GB at 16-bit and 0 GB at 4-bit: the weights (33M parameters) plus a working margin. A long context needs more.

### What is the cheapest GPU to run bge-small-en-v1.5 on?

At 16-bit, 1x MI300X from $1.85 an hour; at 4-bit, 1x MI300X from $1.85 an hour, at the lowest on-demand prices the SAVRN Index lists.

### Can I use bge-small-en-v1.5 commercially?

Yes. bge-small-en-v1.5 is released under MIT License. The MIT License is a short permissive license. It permits commercial use, modification and redistribution, provided the copyright notice and permission notice are included.

### What is bge-small-en-v1.5's context length?

The easiest way to starting using jina-embeddings-v2-small-en is to use Jina AI's Embedding API. jina-embeddings-v2-small-en is an English, monolingual embedding model supporting 8192 sequence length. It is based on a BERT architecture (JinaBERT) that supports the symmetric bidirectional variant of ALiBi to allow longer sequence length. The backbone jina-bert-v2-small-en is pretrained on the C4 dataset. The model is further trained on Jina AI's collection of more than 400 millions of sentence pairs and hard negatives. These pairs were obtained from various domains and were carefully selected through a thorough cleaning process. The embedding model was trained using 512 sequence length, but…

A vision encoder with a runtime-selectable token budget, built to sit between an image and an LLM.
