OpenAI will watermark ChatGPT outputs by default—but only in the EU

What happened: OpenAI will watermark ChatGPT text by default in the EU, and offer the feature elsewhere with it off by default. Key numbers: EU AI Act took effect in August. Why it matters: The EU move is driven by AI Act compliance, which requires detectable marking of AI content. OpenAI says existing standards are easy to circumvent, and it will limit detector access to approved researchers and organizations.
