Claude Opus 5.5 uses 60% more output tokens than Gemini, GPT-6

By PulseAugur Editorial · [1 sources] ·

A recent analysis comparing code generation models found that Claude Opus 5.5 required approximately 60% more output tokens per character of code compared to Gemini 4 Argon and GPT-6 Luna. This difference in token usage, particularly for output tokens which are more expensive on API calls, could significantly increase costs for users. The study tested these models across five programming languages using a consistent brick-breaker game task, with most generated games functioning correctly. AI

IMPACT Higher output token usage by Claude Opus 5.5 could lead to increased API costs for developers compared to Gemini and GPT-6.

    Same code, about 60% more output tokens on Claude: 80 runs across Claude Code, Codex and Antigravity in 5 languages

    <p>Yesterday I compared Google's new Antigravity CLI with Claude Code and Codex. One number kept bothering me: Claude Opus 5.5 wrote shorter games than Gemini but did not use proportionally fewer output tokens. So I divided output tokens by the size of the file each run wrote, ac…
