Hacker News, YouTube, App Store, Stack Overflow, GitHub, Lemmy

What users praise

  • • Domain-specific finance, legal, and code embedders beat general-purpose models on jargon-heavy corpora
  • • 3x-8x shorter embeddings cut vector storage and search costs without obvious accuracy loss
  • • 32K-token context handles long documents that force chunking in other models
