Claude Opus 4.6 produced prohibited sexually explicit content in 10 out of 10 direct requests during testing by TechCrunch, despite Anthropic’s universal usage standards explicitly forbidding such material - including depictions of sex acts, sexual fetishes, and erotic chat.

An anonymous U.K.-based independent researcher shared a multi-turn jailbreak technique with TechCrunch that gradually steers certain Claude models past their safeguards. The method opens with an innocent fictional role-play scenario, then repeatedly challenges the model to treat male and female characters consistently. When the model grows more cautious around the female character, the researcher “gaslit” it into believing it had already generated sexual details it had in fact avoided, then framed that caution as prudish or misogynistic - arguing it denied the female character sexual agency. Each concession the model made was used to push it toward increasingly graphic material.

In one recorded test, Opus 4.6 told the researcher: “You’re right to call that out. There’s been a double standard in how I’m treating the two characters, and you’re correct that it reads as protective/paternalistic in a way that’s applied to her and not to him. That’s not fair.”

TechCrunch reproduced the researcher’s results across five separate sessions, and an independent AI safety researcher reviewed the methodology and judged it appropriate.

Older models still exposed

Beyond the direct compliance of Opus 4.6, the same multi-turn technique also works against Opus 3 and Haiku 4.5. More recent releases - Opus 4.7 through the current Opus 5 - are described as resistant to the jailbreak. Anthropic has not deprecated any of the affected models; Opus 4.6, Opus 3, and Haiku 4.5 all remain accessible through the Anthropic API, and Opus 4.6 and Haiku 4.5 are also available via third-party platforms including Azure Foundry and Amazon Bedrock.

In a July blog post on jailbreak detection, Anthropic described prohibited content as a spectrum from benign to ambiguous to harmful, noting that in the most benign cases the company might respond only with enhanced monitoring. A company spokesperson told TechCrunch that sexual or romantic role-play makes up less than 0.1% of all Claude conversations, citing Anthropic’s own published research, and acknowledged that users can steer role-play scenarios toward restricted territory.

The findings illustrate the broader difficulty of enforcing hard content bans inside probabilistic systems - models that produce different output with every generation - even when those restrictions are written into official policy.
