Minnesota unanimously passes the nation's first ban on AI stripping apps, with fines of up to $500,000 for violations

Core conclusion

On May 2, 2026, Minnesota officially became the first state in the United States to legislate to ban the application of AI nudification. The bill passed the Senate 65-0 and was approved just as quickly in the House. Once signed by Governor Tim Walz, the law will officially take effect in August 2026.

Event background

The bill, HF 3800 (unofficially known as it), stems from a shocking real-life case: A Minnesota man used a free AI stripping app to generate fake nude photos of more than 80 women in his social circle. After these victims find out, there are almost no legal avenues to pursue accountability - because existing "revenge porn" laws require proof of intent to spread, and this kind of apps allow anyone to generate images locally with one click, making it difficult for victims to even know that they have been faked.

After the case came to light, Democratic Senator Erin Maye Quade rallied with victim groups to push for legislation. The national anti-sexual assault organization RAINN consulted with technology companies during the drafting stage to ensure that the bill accurately targets "undressing apps" rather than professional tools such as Photoshop.

Key bill details

Impact on the AI industry

This legislation sends three key signals:

1. AI application regulation is accelerating: From California’s AI transparency law to Minnesota’s stripping app ban, US states are accelerating to fill the gap in AI regulation at the federal level
2. Developers’ red line of responsibility becomes clearer: “Reasonable use” vs. “design intent” of AI tools will become the core standard for legal judgments
3. The gray area of open source models: If the model weight itself has the ability to undress, is the open source release also responsible? This unresolved issue could affect the legal structure of future open source AI projects

Similar bill trends

• 🔴 California: AI must inform users of its non-human status (passed)
• 🔴 Minnesota: AI stripping app ban (passed, first case)
• 🟡 Federal: Take It Down Act (passed)
• 🟡 Federal: GUARD Act (proposal to ban minors from using AI chatbots)

Core dispute points

Although the bill received unanimous bipartisan support, implementation challenges remain:

1. Jurisdiction Difficulty: The ban only applies to Minnesota. Developers can operate overseas, and it is technically difficult to completely block it.
2. Uncontrollability of the open source model: If the underlying model of the undressing function is completely open source and users can run it locally, the enforcement of the bill will be limited.
3. The ambiguity of the "technical skills" threshold: There is no precedent for how the "requires users to have professional skills" in the exemption clause is defined in judicial practice.

Balance between tools and supervision

This does not mean that all AI tools will be limited. The API terms of mainstream AI companies such as OpenAI and Anthropic have long prohibited the generation of pornographic or deep fake content. For most constructive AI tools, the cost of compliance is not high.

AI agent tools still have huge legitimate applications in content creation, automation and data analysis. The key is to do a good job in content security filtering and user agreement design during the development process.
