GPT-Image-2.5 arrives in ChatGPT, but the infamous noise-artifact test still yields mixed results

ElonBaldMusk · x · 2026-09-09

markk reports GPT-Image-2.5 has shipped in ChatGPT with many improvements, and immediately ran his infamous "noise artifact" test (prompt: a detailed photo of a clearing in the woods with green foliage). Results were mixed: ElonBaldMusk complained the patter artifact is everywhere and "even worse than before," while markk judged it not worse but not much better either — suggesting texture artifacts remain a weak spot in the update.
