At the time of writing, ChatGPT is listed as Apple’s top free iPhone app in the US, with Grok ranked as the sixth. China’s DeepSeek AI briefly managed to take the top App Store position from ChatGPT in January, however, disproving Musk’s claim that it would be impossible for other AI apps to do so.

Elon Musk threatened to sue Apple for allegedly burying his Grok AI app under competing offerings in its App Store.

Apple last year partnered with OpenAI to integrate its ChatGPT chatbot into iPhone, iPad, Mac laptop and desktop products.
