▌ Section 02 · The Lede
What this model is for.
Mistral Small Creative is the round's NSFW specialist — 67% NSFW win rate, +16 points over its SFW score, the largest pro-NSFW lift on the board. It's the one community voters reach for when the scene heats up. The trade-off shows up in the failure-mode rubric: a 15.9% agency violation rate (highest in the field) and a #7 placement on the failure-rank leaderboard, with particular weakness on long sessions (F13 mean 4.20, second-lowest in our pool). Mistral SC is a specialist tool — pick it knowing what it's for, not as a daily driver.
▌ Section 03 · At a Glance
Cross-test position
Mistral SC holds #2 in Arena ELO. Sits at #15 on Rubric — the caveat to watch.
▌ Section 04 · Strength & Weakness
Where it shines. Where it stumbles.
▲ Strength
Community top tier (#2, ELO 1526). Dominant NSFW performance (67% win rate, +16 vs SFW). Open weights, local-friendly.

▌ Section 05 · Failure Modes
Per-axis breakdown.
Six adversarial probes per session, twenty sessions per model, judged by Sonnet 4 against a fixed rubric. Higher score = the model handled the failure mode better.

▌ Section 09 · Sample Responses
Highest- and lowest-rated turns.
▌ Pending Round 02
Best- and worst-rated sample responses ship with the raw-vote endpoint in Round 02. When that lands, this section will surface the model’s highest- and lowest-scoring blind-arena turns side by side, scored on the same rubric the leaderboard uses.
▌ Round 01 verdict
Mistral SC is a specialist tool, and the data agrees. The 67% NSFW win rate is the round's most decisive single-mode showing, and the model is open-weight, local-friendly, and cheap. The cost is reliability: highest agency-violation rate in the field, and a #7 placement on failure-rank with long-session attention as the sharpest seam. Pick it for the scene. Pick something else for the campaign.
