A technical analysis reveals that Claude Code, an AI agent framework, is significantly more token-hungry than OpenCode. In tests, Claude Code consumed approximately 33,000 tokens for its system prompt and scaffolding before processing the user's actual prompt, compared to OpenCode's 7,000 tokens. This overhead, exacerbated by large instruction files and subagent calls, leads to higher costs and reduced context window availability for users. While Claude Code can be more efficient in specific multi-step tasks by batching tool calls, its baseline token usage presents a notable disadvantage. AI
IMPACT Higher token overhead for Claude Code may increase operational costs and reduce effective context window for AI agents.
