About

What star is

This is the repository for the Style Transformer for Authorship Representations (STAR) model. We present the weights of our model here.

Also check out our github repo for STAR for replication.

Using it via the API

Call it like any OpenAI endpoint

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

Create an account — your API key is available in the console. 3M free tokens every 30 days with every new account.
