Capabilities

GPT-5.4 scored 77 overall, performing well — a knowledge-first generalist. It stands out in general knowledge (96%), hallucination control (88%) and multilingual capability (87%), combining broad accurate coverage with careful, low-hallucination output, which serves localization and marketing content well. Comparatively, agent collaboration (54%) is weak; tool-orchestration workflows are a stretch. Knowledge-accuracy-first content tasks are where it fits.
