TikTok owner ByteDance has started testing for its ChatGPT-like service Grace (gracebot.cn), with authorized accounts being given the chance to talk with the AI chatbot, local media outlet TechPlanet first reported on Monday. Beijing-based ByteDance labels Grace an “AI partner,” with users able to give a thumbs up or down and ask the AI assistant to regenerate responses, functions that are also embedded in OpenAI’s ChatGPT. The report quoted a ByteDance employee as saying the app currently is “immature,” and acknowledging that “large gaps” existed when compared with leading foreign large language models.
