Suppressing Hallucinations with Formal Verification
devanshmehta · x · 2026-07-11
Someone introduces PramaanaLabs: a company attempting to use formal verification to reduce AI hallucinations.
Core Idea
- One current value of large models is providing answers first, which humans then verify.
- PramaanaLabs aims to eliminate the manual verification step by converting user requirements into a programming language called lean.
- This language automatically rejects outputs that do not satisfy mathematical specifications, preventing erroneous answers from passing through.
Focus Scenarios
The author notes they are currently targeting:
- Tax filing
- Legal cases
- Healthcare
In these scenarios, even a single hallucination can have severe consequences. The author speculates that the company may later pivot toward migrating legacy code into formally verifiable languages.
