Probably develops technology that can prevent LLM hallucinations and simple factual errors. It's a sophisticated security system, which the startup describes as a "mechanical data suit." LLM results are verified using a deterministic validation system that returns any results that don't match the dataset. Each result is accompanied by a link to the source and an audit trail of the development process, a practice that is becoming increasingly common among AI tools.
