How to enable Max reasoning effort
Open Codex Settings → Configuration → Model features → Available reasoning efforts, then select Max. It will appear in model controls for supported models.

The 5h limit is temporarily paused, so Quota Radar currently shows only the active 7d quota. GPT-5.6 estimates include an estimated cache-write surcharge.
Using the latest valid 7d calibration (2026-07-16-am) from a 20x Pro US account. The 5h limit is temporarily paused and is not displayed. Formula: 20x Pro 7d = $214.26 / 15% * 100 = $1,428.41; the API-equivalent cost includes the estimated cache-write surcharge.
Method: Sol, Terra, and Luna use low reasoning effort with the same count-from-1-to-1024 output task. Standard and Fast each run three independent samples and use the arithmetic mean; order alternates, up to three model pairs run concurrently, and each pair still runs Standard/Fast serially. Every sample uses a fresh app-server and ephemeral thread plus a random nonce. Complete outputs with cached_input_tokens = 0 are preferred. For this Jul 14 run, slow samples and one complete Terra cache-mismatched pair are retained as real same-day experience; incomplete outputs are rejected and rerun. TTFT is delay to the first visible token, TPS is sustained token generation speed, and E2E is total time from submission to the complete result. Headline acceleration values are calculated as mean Standard divided by mean Fast; per-model E2E acceleration uses that model's Standard divided by Fast.
