Claude Code sends 33k tokens before reading the prompt; OpenCode sends 7k

https://systima.ai/images/claude-code-vs-opencode-banner.png
Claude Code incurs ~33,000-token overhead per request (vs OpenCode’s ~7,000) due to extensive system prompts, tools, and mid-session rewrites, while OpenCode’s stable, cached prefixes minimize costs. Subagent workflows amplify Claude Code’s token usage 54x vs OpenCode’s lean design, with configuration files and MCP servers further inflating baseline costs.
