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

Key points

• OpenAI will automatically watermark text generated by ChatGPT in the European Union to comply with the EU AI Act. The feature will be optional in other regions.
• The company's proprietary watermarking method, textGrain, embeds patterns in word choices detectable by a specialized tool.
• OpenAI will share the detector with select researchers and organisations, with a process for others to request access.
