(Reuters) - OpenAI is launching a tool that can detect images created by its text-to-image generator DALL-E 3, the Microsoft-backed startup said on Tuesday amid rising worries about the influence of AI-generated content in this year's global elections.

The company said the tool correctly identified images created by DALL-E 3 about 98% of the time in internal testing and can handle common modifications such as compression, cropping and saturation changes with minimal impact. 

The ChatGPT creator also plans to add tamper-resistant watermarking to mark digital content such as photos or audio with a signal that should be hard to remove.
