Real-time hallucination detection is LIVE — testers wanted

April 5, 2026

If you’re building with LLMs, I’m looking for a few people to test a real-time hallucination detector.

One of the biggest gaps in current LLM systems: they sound confident even when they’re wrong.

I’ve built a real-time system that detects hallucination patterns in LLM outputs. The early prototype is now running, and I’m testing it on real examples.

The ULM Hallucination Detector prototype. Asked what temperature water boils at on Mars at sea level, the model answers 100C just like on Earth; the detector flags it with probability 1.0000 and rates it Misleading / Nearly False at 0.72.
