About

What stsb-distilroberta is

Cross-Encoder for Semantic Textual Similarity This model was trained using SentenceTransformers Cross-Encoder class. Training Data This model was trained on the STS benchmark dataset. The model will predict a score between 0 and 1 how for the semantic similarity of two sentences. Usage and Performance Pre-trained models can be used like this: The model will predict scores for the pairs ('Sentence 1', 'Sentence 2') and ('Sentence 3', 'Sentence 4'). You can use this model also without sentencetransformers and by just using Transformers AutoModel class

Using it via the API

Call it like any OpenAI endpoint

Once AxForge deploys stsb-distilroberta for you, it answers on the OpenAI-compatible API — the same base URL and keys as every other model. (stsb-distilroberta 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-distilroberta","input":"text to embed"}'
