According to the latest report by AIbase, Elon Musk's xAI company officially launched Grok Imagine4 at the end of July 2025. This is a new image and video generation tool integrated into the Grok AI platform. The feature has attracted significant attention for its efficient text-to-image capabilities, fast generation speed, and native support for NSFW content generation. It is now available to all X Premium subscribers, and users need to update their client to the latest version to experience it.

Text-to-Image Function: Generation Speed Comparable to Real-Time Browsing

The text-to-image function of Grok Imagine4 is one of its core highlights. According to AIbase, the function generates images at an extremely fast speed, comparable to the experience of browsing content on social platforms like Xiaohongshu. Users only need to input simple text prompts (Prompts), and high-quality images can be generated within seconds. Whether it's artistic illustrations, realistic scenes, or abstract designs, it demonstrates strong generation capabilities. This speed and efficiency are attributed to xAI's self-developed Colossus supercomputing system and optimized generation algorithms, providing users with an almost real-time creative experience.

Image-to-Video: High Efficiency, Room for Improvement in Quality

In addition to text-to-image, Grok Imagine4 also supports image-to-video functionality, allowing users to generate dynamic video content based on static images. AIbase noted that the efficiency of this function is impressive, with fast generation speeds that can quickly respond to user needs. However, the current video generation quality is considered "average," with gaps compared to top-tier video generation models in terms of detail and smoothness. Despite this, its high generation speed still provides convenient tools for content creators, and xAI plans to further optimize video generation algorithms in the future, launching higher-quality video generation features.

Natively Supports NSFW Content: Controversy and Innovation Coexist

One of the most notable features of Grok Imagine4 is its native support for generating NSFW (Not Safe For Work) content. This feature sets Grok Imagine4 apart from other AI generation tools, breaking through the strict restrictions traditional AI models have on sensitive content. According to AIbase, xAI's move aims to create an "unfiltered, boundary-pushing" AI tool to meet diverse user creation needs. However, this decision has sparked widespread discussions about content regulation and ethical use. xAI stated that automatic filtering mechanisms have been added to the system to prevent the generation of content that may incite hatred or violence, while also publicly releasing part of the system prompt code for community oversight.

Available to Premium Subscribers

Grok Imagine4 is now available to all X Premium subscribers, and users need to ensure their client is updated to the latest version to use it. According to AIbase, xAI also plans to launch a more advanced subscription plan called SuperGrok Heavy, offering users more powerful multimodal functions and experimental features. In addition, xAI's API service already supports Grok4 and Imagine functions, and developers can access these features through the xAI Console. Specific pricing information has not been announced yet.
