Lech Mazur's Short Story Creative Writing Benchmark (59 writer models, 110,748 judgments, three cross-family judges, both presentation orders) updated. Muse Wonder (high) scores 1.96 vs 0.56 for Muse Spark 1.3. Gemini 4 Argon (high) hits 0.80, up from −2.17 for Gemini 3.1 Pro Preview, winning all 50 matched comparisons with better use of required elements — though it still repeats names and resolves emotional conflict too neatly. Claude Fable 5.1 (3.76), Claude Opus 5.5 (3.71) and GPT-6 Astra (3.44) lead the chart.
