CORRECTED 2026-10-03 23:15 UTC — Correction — The original workload example overstated both dollar amounts by 1,000×. Using the rates quoted in this item, 100M prompt tokens per day cost $0.51 before and $1.54 after, excluding other charges. This verifies internal arithmetic only; historical source rate applicability and effective dates remain unverified.
