GLM 5.2 vs Mistral Large for fiction writing

Judged blind on fresh genre scenes (LitRPG, cozy mystery, romance, thriller, xianxia…), July 2026 — three tries per model per scene, passages shown in both orders so position can't sway it, graded by a third AI that isn't either of them.

The score is each model's overall strength across the whole 8-model field (like a chess rating); the range next to it is where the true score most likely sits. Slop is a separate count of AI tells (lower is cleaner) — it isn't part of the ranking.

GLM 5.2:

The quest had glitched on the third turn-in. Maren had seen it before — NPCs stuck in looping dialogue when a flag failed to fire. She clicked through Edda's speech again, half-watching, half-watching a stream on her second monitor. "The winters grow crueler each year. You've proven yourself a friend to *cramped* Villenheim. Take this reward, and may the frost stay beyond your door." She accepted the gold, checked the quest log. Still marked incomplete. She sighed and clicked Edda again. "The winters grow crueler each year. You've proven yourself a friend to *drafty* Villenheim. Take this reward, and may the frost stay beyond your door." Maren frowned. She rewound the stream thirty seconds. She was tired. That was all. She turned in the quest a third time. "The winters grow crueler each year. You've proven yourself a friend to *third-floor* Villenheim. Take this reward, and may the frost stay beyond your door." Her hand stopped on the mouse. She read it again. *Third-floor.* Villenheim was a hamlet, not a …

Mistral Large:

The tavern’s hearth crackled, casting long shadows across the scarred oak tables. Kael leaned back in his chair, swirling the dregs of his ale as the barkeep—a burly man with a face like weathered leather—wiped down the counter for the third time in as many minutes. "Rough night out there," the barkeep said, nodding toward the rain-lashed windows. "Storm’s got the roads flooded near the Black Hollow." Kael grunted. "Heard the same from the stablehand. Thanks for the warning." The barkeep paused, rag hovering over a tankard. "Rough night out there," he repeated, voice flat. "Storm’s got the roads *cluttered* near the Black Hollow." Kael’s fingers tightened around his mug. *Cluttered?* That wasn’t a word you used for roads. That was a word for his apartment—his *real* apartment, back in the city, where takeout containers and half-read books piled up like drifts of snow. The game couldn’t know that.

How it works: every pair of models is judged blind on the same scene, with the passages' order flipped so being shown first can't sway it, by GPT-5.4 — a family that isn't on the board, so nobody scores their own side. Each score carries a likely range; overlapping ranges are called a tie. Slop is scored separately by a fixed checklist, not an AI. Full board, every prompt, and the FAQ: thebookfactoryai.com/board.
