The passage around this formula
Therefore a product claim such as “Model A scores x ” should usually be rewritten as “Model A with harness H, tool set T, budget B, and configuration C scored x on dataset version D.” When OpenAI reports GPT-5.3-Codex benchmark values, its appendix specifies xhigh reasoning effort and the surrounding Codex evaluation configuration [ 12 ] . Those are vendor-reported system results. They should not be compared to a competitor’s model-only API result without harmonization.
