Interpretation

Why the result lands here.

This is a top-tier all-around entrant: the aggregate score remains close to the leader, with lane-level tradeoffs shown separately. Hard Intelligence score is 88.28 and contributes to the overall score alongside Full/Agentic and SWE. Runs on the ChatGPT Codex subscription; the transport is the Codex Responses route rather than a metered API key. Reasoning effort is extra-high on every lane. OpenAI documents none/low/medium/high/xhigh for gpt-5.5, so this is the model's ceiling and no higher level exists to leave unused. Costed at the model’s published Standard API rates ($5.00/1M input, $30.00/1M output) as a comparable basis, not an invoice: the subscription bills no marginal per-token charge. Hard Intelligence is a public diagnostic, not a hidden official score. Token median and P90 per scored item are intentionally omitted: their derivation could not be reproduced on the same basis as the published rows.
