About

What allenai-specter is

allenai-specter This model is a conversion of the AllenAI SPECTER model to sentence-transformers. It can be used to map the titles & abstracts of scientific publications to a vector space such that similar papers are close. 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.

Using it via the API

Call it like any OpenAI endpoint

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