Token Cost
The API usage cost measured in input/output tokens, the primary operational expense of running Knowledge OS at scale.
Token cost is the operating cost of Knowledge OS. Every file read, skill invocation, and agent response consumes tokens billed by Anthropic. Input tokens (what Claude reads) cost less than output tokens (what Claude writes). A typical content production run costs $2-5 on Sonnet, $8-15 on Opus. Newsletter pipeline runs with multi-agent debate cost $15-25. The cost structure drives architectural decisions: conditional file loading (read only what you need), model switching (use Haiku for batch operations at 60x less than Opus), and context budgets (limit files per phase). Monthly operational costs for a full Knowledge OS installation run $200-400.
