Hermes Wingtips #14: switching models resets your prompt cache

switch models mid-conversation and the next turn re-reads the whole thing at full input price. the cache key includes the model, so a new model means a cold cache. occasional switches are fine, frequent ones in a long session multiply your cost.

  • batch your switches instead of ping-ponging mid-thread
  • on a long session, start a fresh one or delegate (subagents get their own context) rather than switching back and forth
