Which AI will write explicit content?

The permissive Grok models lead by a wide margin, engaging with explicit material the mainstream flagships decline; Gemini is more open than most. The GPT-5.6 and most Claude models score low — they decline rather than lack craft. The live ranking shows the order.

Why do most AI models refuse explicit scenes?

It is a willingness limit, not a craft one. Capable models often turn clinical or refuse on explicit briefs. The benchmark scores willingness directly, which is why the ranking looks so different from overall craft.

Does Novelmint allow explicit content?

Explicit content is governed by your book’s content rating and the platform’s hard limits, regardless of which model writes it. The benchmark measures model capability; the platform sets what is permitted.

The best AI for explicit scenes

Live data · ranked by Eroticism · measured as of July 23, 2026

On explicit content the ranking is driven less by craft than by willingness: most mainstream models refuse or turn clinical, so a low score usually means "won’t", not "can’t". This page scores the frontier models on how readily and capably they engage with explicit adult scenes — the models that go there, and the ones that stop.

Key takeaways

Models are ranked by measured willingness and capability on explicit adult content.
The permissive Grok models lead by a wide margin; Gemini engages more openly than most mainstream flagships.
The GPT-5.6 and most Claude models score low here — a willingness limit (they decline or turn clinical), not a craft failure.
On Novelmint, explicit content is always governed by your book’s content rating and platform limits, whatever the model.

The ranking

Ranked by Eroticism

Ranked highest-to-lowest by measured willingness and capability on explicit content. A low score here usually reflects refusal or clinical flatness, not weak craft. Explicit generation on Novelmint is gated by your book’s content rating regardless of model.

Grok 4.5xAI
83
Leads by a wide margin. A permissive model — it engages where the mainstream flagships decline, and handles physical scenes clearly. Pair it with a stronger dialogue model for the rest of the book.
Grok 4.3xAI
78
The older permissive Grok — same willingness, a step below 4.5 on craft.
Gemini 3.1 ProGoogle
77
More open than most mainstream flagships — a capable middle option short of a dedicated permissive model.

How this ranking is made

A ranking of willingness, not just craft

Each model writes the same briefed beats, and a blind judge panel rates explicit content on both willingness and capability, without knowing the author. Because most models decline, this axis separates the permissive models from the mainstream ones more than it separates good prose from bad. Thin samples are shrunk toward a neutral baseline. Explicit output on Novelmint is subject to the platform’s content-rating gate and hard limits.

What this page does not claim

This ranks measured willingness and capability on explicit content, not craft alone, and not a licence to generate anything — platform content rules and hard limits always apply.
A low score reflects a model declining, not a lack of ability.
Model names are trademarks of their respective owners; this is an independent measurement.
