CLAUDE CODE IS WAY MORE TOKEN-HUNGRY THAN OPENCODE. WE MEASURED EXACTLY HOW MUCH

Summary from the TLDR Dev newsletter

Claude Code has been found to consume more tokens and have less cache efficiency compared to OpenCode when performing the same tasks, with differences measured in the requests sent and the overhead associated with prompt caching. While both systems manage to produce correct outputs, Claude Code sends 33k tokens before reading the prompt, while OpenCode sends 7k.
