Two EU AI Act translations use FLOPs/s instead of cumulative FLOPs An Arxo register entry, ARXO-2026-0413, reports that the Portuguese and Croatian versions of the EU Artificial Intelligence Act, Regulation (EU) 2024/1689, measure the 10^25 threshold in Article 51(2) in floating point operations per second rather than as a cumulative total, unlike the other 22 language versions. Arxo states that Recital 111 and Annex XIII, point (c), support a total number of operations, and that under a constant training rate 2×10^25 operations over a million seconds equals 2×10^19 operations per second — above the total threshold but below the rate. Arxo proposes deleting the words "per second" ("por segundo", "u sekundi") from Article 51(2) and reported the discrepancy to the Council of the European Union's Directorate for Quality of Legislation on 2026-10-31; the official text was unchanged at last check. ARXO-2026-0413 · Reported AI Act, Portuguese and Croatian versions: the 10^25 threshold of Article 51 2 is measured per second The other 22 versions measure the cumulative amount of computation in floating point operations, without a time unit. The added words do not fit the cumulative quantity described in the same paragraph. Recital 111 and Annex XIII, point c , support a total number of operations. Consequence In a hypothetical case with a constant training rate, 2×10^25 operations over a million seconds means 2×10^19 operations per second. The total is above 10^25; the rate is not.
