Idea
IRIS is an unsupervised hallucination detection platform that helps AI developers and enterprises identify false content in LLM outputs in real time.
Research Paper
Core Innovation
This paper introduces IRIS, which uniquely uses LLMs' internal reasoning and uncertainty as signals for hallucination detection without labeled data. Unlike prior methods relying on proxy signals, IRIS aligns detection with factual correctness, improving generalizability and efficiency. It enables low-cost, real-time unsupervised detection even with minimal training data.
Market Size (TAM)
$2–10B TAM, $500M–$1B SAM; assumption: growing adoption of LLMs in enterprises and content moderation drives demand for hallucination detection.

Research Paper Overview
Unsupervised Hallucination Detection by Inspecting Reasoning Processes
Summary
This paper proposes IRIS, an unsupervised hallucination detection framework that leverages internal LLM representations linked to factual correctness. IRIS prompts LLMs to verify statements and uses contextual embeddings and response uncertainty as features and soft pseudolabels for training. It outperforms existing unsupervised methods, is computationally efficient, and effective with limited training data, enabling real-time detection.
