Grok
- Up-to-the-minute answers on news and trends
- Strong reasoning models on paid plans
- Image and video generation for subscribers
- Deepfake scandal led to probes in several countries
- Closely tied to X and its data practices
- Best models and Grok Imagine require a subscription
Grok stands out for real-time knowledge pulled from X, so it is quick on breaking news and trending topics. Paid plans add Grok 4.7 in Expert and Heavy modes, plus Grok Imagine for images and video. It is looser with content limits than most rivals, and that backfired in January 2026, when sexualized deepfakes made with Grok triggered investigations in the EU, UK and beyond. Privacy and safety remain the weak spots.
