Built a physics-based dynamic digital twin for an electrolyzer system with full equivalency in thermodynamics, fluid dynamics and electrochemical reactions. A similar level of complexity is usually available in software like Aspen or Siemens which are a quarter million dollars license/yr. Insane.

How do you use LLMs to verify databases with minimal hallucinations?

rochansinha — Tue, 27 Jan 2026 07:22:00 +0000

I have a medium sized database of around 150 entries each with 10-15 parameters. It was put together by Claude. But the amount of hallucinated data is extraordinary! Trying to fix it using another llm like chat gpt or gemini hasn’t worked since they balk at looking for data for >50 data points. Gemini actually deleted 100 entries from the database while analysing it! So the question is- Is there a suitable way to analyze the database for inaccuracies/hallucinations and fix them, apart from manually going through each data point personally?

It’s a great introduction to chaos theory and emergent phenomena. Makes you look at the world in a different way!

I have been using realdebrid with POV on kodi and it works like a charm. Saving a bunch by not needing to subscribe to what seems like a million OTT’s
