About

What stsb-bert-tiny-safetensors is

sentence-transformers-testing/stsb-bert-tiny-safetensors This is a sentence-transformers model: It maps sentences & paragraphs to a 128 dimensional dense vector space and can be used for tasks like clustering or semantic search. Usage (Sentence-Transformers) Using this model becomes easy when you have sentence-transformers installed: Then you can use the model like this: Usage (HuggingFace Transformers) Without sentence-transformers, you can use the model like this: First, you pass your input through the transformer model, then you have to apply the right pooling-operation on-top of the contextualized word embeddings. Evaluation Results For an automated evaluation of this model, see the Sentence Embeddings Benchmark: https://seb.sbert.net Training The model was trained with the parameters: DataLoader: torch.utils.data.dataloader.DataLoader of length 360 with parameters: Loss: sentencetransformers.losses.CosineSimilarityLoss.CosineSimilarityLoss Parameters of the fit()-Method: Full Model Architecture Citing & Authors

Using it via the API

Call it like any OpenAI endpoint

Once AxForge deploys stsb-bert-tiny-safetensors for you, it answers on the OpenAI-compatible API — the same base URL and keys as every other model. (stsb-bert-tiny-safetensors below is illustrative; you get the exact model name on deployment.)

$ curl -sS https://api.axforge.ai/v1/embeddings \
  -H "Authorization: Bearer $AXFORGE_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"model":"stsb-bert-tiny-safetensors","input":"text to embed"}'

Licence

Commercial licence needed

The weights are open but its licence needs a commercial agreement for business use. AxForge can arrange that licence and host the model for you — you pay AxForge, we settle with the model’s maker. Ask us for a quote. Read the licence ↗
