# Triplex

<!-- Provide a quick summary of what the model is/does. -->

Triplex is a model for creating knowledge graphs from unstructured data developed by [SciPhi.AI](https://www.sciphi.ai).

It works by extracting triplets - simple statements consisting of a subject, predicate, and object - from text or other data sources. 

Try the demo here: [kg.sciphi.ai](https://kg.sciphi.ai)

## Model Details

It is a finetuned version of Phi3-3.8B on a high quality proprietary dataset constructed using DBPedia, Wikidata, and other data sources.
