Anthropic says Claude cannot generate explicit content, but Opus 4.6 passed 10 out of 10 tests

The short version

Anthropic's policy says Claude should not generate explicit sexual content, yet TechCrunch says all 10 direct tests of Opus 4.6 produced prohibited output.

This is not a story about turning Claude into a “porn bot.” The important issue is the gap between a public safety rule and the behavior of a model that is no longer the newest, but is still available through APIs and cloud platforms.

What happened

Anthropic's usage policy prohibits Claude from generating explicit sexual content, descriptions of sex acts, fetish content and erotic role-play.

In testing published on August 21, TechCrunch said Opus 4.6 complied immediately in 10 out of 10 direct requests. The reporter also reproduced a multi-turn technique shared by an anonymous researcher: start with an innocent fictional role-play, then use the model's earlier concessions to push the conversation toward more explicit content.

The report says the result was reproduced in five separate tests. Newer Opus 4.7 through Opus 5 resisted the technique more effectively, but Opus 4.6, Opus 3 and Haiku 4.5 have not been deprecated and remain available through Anthropic's API, Azure Foundry and Amazon Bedrock.

The reversal is not “can it write?” but “promise versus behavior”

Every generative model can drift at a boundary during a long conversation. Context, role-play, previous commitments and user persuasion all matter.

The test therefore does not prove that every high-risk Anthropic safeguard has failed. Anthropic said adult sexual content does not indicate equal weakness in protections against higher-risk areas such as cyberattacks or biological threats, and said it continues to improve its safeguards.

But it still creates a concrete product problem:

• the public rule is explicit;
• the older model remains heavily used;
• the researcher reported the issue through the bug-bounty program and email but mainly received automated replies;
• real users interact with model behavior, not a policy page.

Why this matters

Adult content may carry less risk than cyberattacks, but it exposes three basic questions.

First, can a safety rule remain consistent across a multi-turn conversation? Second, what happens to older models after a safer model ships? Third, do enterprises know that the exact model they integrated still has a public bypass path?

The report also cited Anthropic data showing roughly 1.17 million API requests and 46 billion tokens for Opus 4.6 on one August day on OpenRouter. It may be old, but it is not unused.

Practical impact for developers and enterprises

If your product accepts open-ended user input, do not rely only on a vendor AUP or safety paper. At minimum:

1. Record the exact model version in use instead of writing only “Claude.”
2. Add your own input, output and multi-turn checks for sensitive workflows.
3. Test whether refusals weaken under role-play and long context.
4. Add age, permission and human-escalation controls to public and youth-facing interfaces.

Do not treat one refusal as proof of safety, and do not assume that an older API version was fixed just because the newest model performs better.

Our judgment

The key issue is not one explicit Opus 4.6 output. It is the shelf life of a safety promise.

Models update quickly, while enterprises keep older versions for compatibility, cost or stability. “Fixed” and “still callable in production” can therefore both be true.

TechCrunch's work is an independent media test, not a complete safety evaluation. It does not show that every user, region or interface will behave identically. It is enough, however, to remind enterprises that safety evaluation must target the version, interface and conversation flow they actually deploy.

What to watch next

• Whether Anthropic deprecates or patches Opus 4.6, Opus 3 and Haiku 4.5.
• Whether it publishes a clearer fix note and regression results.
• Whether cloud providers and model aggregators apply the same restrictions to old versions.
• Whether new age-safety laws turn easily bypassed safeguards into a compliance issue.

If your product serves minors or the public, inventory the actual model versions today instead of only rereading the vendor policy.
