About

What bert-tiny is

This is the smallest version of 24 smaller BERT models (English only, uncased, trained with WordPiece masking) released by google-research/bert.

These BERT models was released as TensorFlow checkpoints, however, this is the converted version to PyTorch. More information can be found in google-research/bert or lyeoni/convert-tf-to-pytorch.

Using it via the API

Call it like any OpenAI endpoint

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