Codex and Claude differ in model AND native runtime, so this is a system comparison, not a model-controlled or fresh blind test. The adapter developer for the Claude arm was itself a Claude Code session on the same model. No superiority claim is added.",

Token totals are tokens_cli_reported (Claude Code's own cumulative modelUsage). The adapter-recorded usage.tokens undercounts output (partial stream snapshots) and is superseded for reporting; the adapter was frozen and not changed."
