Elon Musk’s xAI company has released a new version of its AI assistant called Grok 2. This update brings exciting new features and improvements to X (formerly Twitter) users with Premium or Premium+ subscriptions.
What’s New in Grok 2
Advanced Image Generation: Grok 2’s standout feature is its powerful image generation capability, powered by the integration with Black Forest Labs’ FLUX.1 model. This allows users to create photorealistic images directly within the Grok 2 interface by simply typing text prompts.
Key aspects of Grok 2’s image generation include:
- Photorealistic Results: The FLUX.1 model produces highly convincing images that can depict a wide range of scenarios. For example, users can generate images such as “a rainforest trail with sunlight filtering through the trees” or “a futuristic city skyline at sunset.”
- Controversial Content: Grok 2 can also create more sensitive or unusual images, including those of public figures in unexpected situations. For example, users have reported creatingimages such as “Mario drinking beer on the beach” or “Donald Trump holding the belly of pregnant Vice President Kamala Harris” While this flexibility allows for creative expression, it also raises ethical concerns.
- Ease of Use: Users can generate images by typing prompts into the chatbot, similar to how OpenAI integrated DALL-E 3 into ChatGPT. This user-friendly approach allows for quick and intuitive interactions.
- Direct Posting to X: Generated images can be shared instantly on users’ X accounts, making it easy to share creative content.
- Lack of Safeguards: Currently, there appear to be minimal guidelines or restrictions to prevent misuse of the image generation feature. The images also lack watermarks or indicators that they were generated by AI, raising concerns about the potential for misinformation.
- Customization Potential: The underlying FLUX.1 model can be adapted using techniques like low-rank adaptation (LoRA) to generate images of specific people in different situations, increasing the creative possibilities for users.
Improved Capabilities: Grok 2 is better at chatting, coding, and reasoning than the previous version, Grok-1.5.
Two Versions: There’s a full Grok 2 and a smaller Grok 2 mini, each with distinct capabilities.
Grok 2 vs Grok 2 Mini: Key Differences

| Speed | Slower due to complexity | Faster response times |
| Image Generation | Advanced image generation | Basic image generation |
| Use Cases | Complex tasks (chat, coding, etc.) | Fast, efficient answers |
| Integration with FLUX.1 | Full integration for advanced capabilities | Utilizes FLUX.1 for image tasks |
| User Interaction | More intuitive and versatile | Efficient but simpler interaction |
| Target Users | Premium and Premium+ subscribers | Premium and Premium+ subscribers |
How Good is Grok 2?
According to xAI, Grok 2 outperforms some other popular AI assistants such as Claude 3.5 Sonnet and GPT-4-Turbo in certain tests. It excels in various academic benchmarks, showcasing its advanced capabilities in reasoning, math, and coding.
Concerns and Challenges
Potential Misuse: Some people worry that Grok 2’s image generation could be used to create fake pictures of real people or spread false information, especially given its permissive nature in generating controversial content.
Election Concerns: With the U.S. presidential election coming up, there may be pressure on xAI to place restrictions on the types of images Grok 2 can generate, especially regarding political figures.
What’s Next for Grok
xAI plans to continue to improve Grok and add more features in the future. They’re also working on making Grok available to businesses through an API (a way for different computer programs to work together).
How to Try Grok 2
To use Grok 2, you need to:
- Have an X Premium or Premium+ subscription
- Update your X app to the latest version
- Look for the Grok tab in the app
Both Grok 2 and Grok 2 mini represent significant improvements over the previous Grok-1.5 model, with enhanced capabilities in areas like chat, coding, and complex reasoning tasks. As users, we should be careful about the information and images we create and share with AI assistants like Grok 2, while appreciating the technological advances they represent.
