Where KV-Cache Error Lives in Looped Language Models: A Diagnostic Study of Ouro and Huginn

Source ↗

Key Insights

  • A looped language model applies one block of layers 4 times per token and keeps a key/value (KV) plane for each loop.
  • We study where storage error changes the next-token distribution and how shared-we.
