Show HN: Halgorithem – an open-source tool for detecting AI hallucinations

- AI hallucinations are when large language models (LLMs) like GPT-4, Claude, or Gemini confidently produce false or nonsensical information, often due to lacking genuine understanding or authoritative knowledge sources. - Halgorithem is a new open-source tool (from Tangible Research) that aims to detect such hallucinations, making AI outputs more reliable without relying on proprietary services. - Open-source means its code is publicly available for anyone to inspect, modify, or deploy — unlike closed, paid detection services offered by some AI companies. - The name is a portmanteau of "hallucination" and "algorithm," possibly riffing on the common tech naming pattern "-orithm" popularized by tools like "algorand" or "algorithmia." - This matters because hallucination is a major barrier to using AI in high-stakes fields (medicine, law, finance); an open-source detection tool could democratize trust in AI outputs.
