Model reference · open weights
specter is an open-weight embedding model from allenai, listed in the AxForge catalogue. AxForge can bring it up on EU-owned hardware for you on request — with the licence handled where one is required.
About
SPECTER SPECTER is a pre-trained language model to generate document-level embedding of documents. It is pre-trained on a powerful signal of document-level relatedness: the citation graph. Unlike existing pretrained language models, SPECTER can be easily applied to downstream applications without task-specific fine-tuning. If you're coming here because you want to embed papers, SPECTER has now been superceded by SPECTER2. Use that instead. Paper: SPECTER: Document-level Representation Learning using Citation-informed Transformers Original Repo: Github Evaluation Benchmark: SciDocs Authors: Arman Cohan, Sergey Feldman, Iz Beltagy, Doug Downey, Daniel S.

How it works
Variants
Open weights ship in several sizes and precisions. One page, all the variants — pick the one that fits your GPU. VRAM figures are estimates from model size.

Using it via the API
Once AxForge deploys specter for you, it answers on the OpenAI-compatible API — the same base URL and keys as every other model. (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":"specter","input":"text to embed"}'
Licence
Open weights under apache-2.0 — commercial use is permitted. Deploy it on AxForge EU hardware on request. Read the licence ↗
