Elon Musk-owned xAI added the feature to its Grok AI model, which understands images. The meaning of this is that the paid users on his social platform X, with the ability to have access to his AI chatbot, will be able to upload an image and ask questions from the AI about the uploaded image.
An employee at xAI and the official @grok handle published on X about the update on Monday.

In another post, Musk said that Grok can even explain the meaning of a joke using the new image understanding feature. "This functionality is in very early stages — suggesting it will rapidly improve," he added.

In August, Musk's AI company launched Grok-2, which was an advanced version of the chatbot with image generation features based on the FLUX.1 model developed by Black Forest Labs. Just like previous releases, Grok-2 would be accessible to developers or X premium (paying) users.
At the time, xAI reported a future release would integrate multimodal understanding to Grok on X and the model it provides through its developer API.

Grok may soon be able to read documents too, Musk responded to one user who criticized the model for its inability to process some file formats-so-called files like PDFs. "Not for long," said Musk, boasting that "we are getting done in months what took everybody else years.".

The social network has attempted to include more features in both the AI chatbot and paid user tiers of X to make the offering more appealing. Last month, X released a new tool called Radar for Premium+ subscribers, which will enable them to observe real-time trends and provide insights into conversations.
