About
We trained the PwC-Embedding-expr model on top of the multilingual-e5-large-instruct embedding model. To enhance performance in Korean, we applied our curated augmentation to STS datasets and fine-tuned the E5 model using a carefully balanced ratio across datasets.
⚠️ This is an experimental model and is under continuous development.
PwC-Embedding_expr was evaluated on the Korean subset of MTEB. A leaderboard link will be added once it is published.

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