A technical analysis by Systima Technologies reveals that Anthropic's Claude Code consumes significantly more tokens than its competitor OpenCode, even before user input. Claude Code initiates sessions with approximately 33,000 tokens for system prompts, tool schemas, and injected scaffolding, compared to OpenCode's 7,000 tokens. This difference is attributed to Claude Code's extensive suite of background agents and reminder blocks, as well as larger system prompts. Furthermore, Claude Code's prompt caching mechanism is less efficient, leading to higher costs due to frequent cache writes, a factor that can dramatically increase token usage in production environments.
