Claude Code's compaction costs vary widely based on cache status

By PulseAugur Editorial · [1 sources] ·

Claude Code, running on Opus 5.5, incurs significant costs for session compaction, especially when the prompt cache expires. A warm cache compaction of 136k tokens costs approximately $0.06, while a cold cache compaction of the same size jumps to around $0.54. The /clear command, intended to reset the session, costs nothing and effectively starts a new session with a clean slate, though the subsequent turn may incur costs for rebuilding the cache. AI
