Original: Post 3 - Building AI You Can Trust

Short summary

The author highlights a core flaw in standard AI retrieval systems: they conflate similarity with currency, returning outdated facts alongside current ones because the two look nearly identical. This blind spot explains many cases where AI assistants confidently give answers that used to be true but no longer are. The post teases a deeper solution in future entries.

  • •Standard retrieval systems cannot distinguish current facts from outdated ones
  • •Similarity and temporal validity are different problems often conflated
  • •This blind spot causes confidently wrong but formerly correct AI answers

Generated with AI, which can make mistakes.
