What this trail covers

Pinecone Assistant is a fully managed service for building AI assistants over private data. This post details the development of a new benchmarking scheme, the 'Answer Alignment Score', to measure the quality of AI assistant answers. This metric aims to improve upon existing unsupervised metrics by using a supervised protocol that extracts atomic facts from ground truth answers and classifies the generated answer's entailment, contradiction, or neutrality towards each fact. The post presents results comparing Pinecone Assistant against OpenAI assistants on three benchmark datasets (FinanceBench, Open Australian Legal, NQ-HARD), showing Pinecone Assistant's outperformance. Future work includes automating benchmark results generation for arbitrary datasets.
