Veridical Intelligence

Fact API for language models

Language models that can show their sources.[1]

Veridical Intelligence is a natural-language API that your LLM can ask about facts. Every answer comes back with references, so your model can cite what it says instead of making it up. Our goal is to eliminate hallucination.

Product

The Veridical API

A natural-language API your model can talk to about facts. It answers in plain language and returns the references behind each answer.

Service

Integration help

We work with your engineers to connect the API to your models and applications, so grounded answers reach your users quickly.

How it works

The API sits between your model and the answer your users see.

Step 1

Your model asks

When your LLM needs a fact, it asks the Veridical API in plain language.

Step 2

We answer

The API replies with the fact and the references that support it.

Step 3

Your model cites

Your model builds its response from referenced facts, not from guesses.

Result

Users can check

Every claim your users read can be traced back to its source.

Who we are

Our team brings decades of software engineering experience and years of hands-on work with AI. We built Veridical Intelligence because we think language models are only as useful as they are truthful.
