Overview

Talarion maintains a knowledge base of verified, dated assertions. Each assertion is structured as a Q/A pair and included in search results if and only if the querying LLM would otherwise answer the underlying question incorrectly. Each search query is mapped to a set of relevant assertions, each of which is rigorously timestamped and includes source URL(s) for provenance verification.

Talarion is designed to power any LLM application which is world-state dependent. From global and local news to developments in financial markets, public policy and fundamental scientific research, Talarion scans the web and catalogues high-surprisal developments.

There are two ways to use it.
