LLM Challenge

Don’t let LLM hallucinations
corrupt your data

A dual-LLM consensus engine ensures only accurate data makes it into your API, ETL and HITL workflows.

Trusted by forward-thinking engineers

Add a trust layer to AI document data extraction

Verify outputs with two LLMs

Two LLMs run your prompts in parallel: an extractor and a challenger. Get an output only if both agree—NULL if not. Configure any combination: OpenAI + Claude, Azure GPT + Vertex + more!

Get drilled-down insights by running the metadata for every extraction. Track token costs, view challenger confidence scores, or debug outputs after deployment.

Frequently asked questions

01Which LLM combinations work best?

We recommend pairing LLMs from different providers. Popular combinations: OpenAI GPT-4 + Google Gemini Pro, Anthropic Claude + Cohere, OpenAI + Anthropic.

The field returns NULL.

Typically adds 2-5 seconds to extraction time. For financial and legal documents, accuracy trumps speed.

Technically yes, but you shouldn’t! Using the same model (or even models from the same provider) defeats the purpose because they tend to make similar mistakes. Provider diversity is key to catching different error patterns.

Important distinction: NULL means “we couldn’t reach consensus.” Empty means “we agreed this field has no value.”

Yes. The full conversation log is available via API for every extraction. You can see why the LLMs disagreed and the confidence score given by the challenger LLM.

Secure and Compliant, Always

Unstract adheres to the strict rules and regulations of various compliance authorities. Rest assured, we have policies, systems, and processes to ensure that your data is always safe, secure, and private.
