OpenAI has paused a voice mode option for ChatGPT-4o, Sky, after backlash accusing the AI company of intentionally ripping off Scarlett Johansson's critically acclaimed voice-acting performance in the 2013 sci-fi film Her.

In a blog defending their casting decision for Sky, OpenAI went into great detail explaining its process for choosing the individual voice options for its chatbot. But ultimately, the company seemed pressed to admit that Sky's voice was just too similar to Johansson's to keep using it, at least for now.
