About
This is a sentence-transformers model: It maps sentences & paragraphs to a 384 dimensional dense vector space and can be used for tasks like clustering or semantic search.
This model aims to provide an embedding finetuned to UK legislative language.
The model is used in an i-dot-ai project to give better semantic searching results for legislation.
The model has been finetuned on 6k question answer pairs from UK public general acts. The question and answer pairs can be found here: (i-dot-ai/legislation_2021-2023_qa)
The answers are sections from UK public general acts from 2010-2023. The matching questions are generated by gpt-4o.
The model performs similarly well to text-embedding-3-large. The finetuning has increased performance by 12% against it's base model all-miniLM-L6-v2.
Using this model becomes easy when you have sentence-transformers installed:
pip install -U sentence-transformers
Then you can use the model like this:
from sentence_transformers import SentenceTransformer
sentences = ["This is an example sentence", "Each sentence is converted"]
model = SentenceTransformer('{MODEL_NAME}')
embeddings = model.encode(sentences)
print(embeddings)
The model was evaluated against 1000 question and answer pairs from UKPGA 2010-2023 with questions generated by gpt-4o.
For an automated evaluation of this model, see the Sentence Embeddings Benchmark: https://seb.sbert.net

Using it via the API
Once AxForge deploys all-minilm-l6-ukpga-6k-finetune for you, it answers on the OpenAI-compatible API — the same base URL and keys as every other model. (all-minilm-l6-ukpga-6k-finetune 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":"all-minilm-l6-ukpga-6k-finetune","input":"text to embed"}'
