Elon Musk's xAI recently released its latest artificial intelligence model—Grok 4, which serves as a direct competitor to OpenAI's GPT-5. Despite experiencing latency in the release process, Musk talked about Grok 4's significant advancements in multimodal capabilities during a live broadcast, enabling reasoning and responses across text, images, and audio. However, the launch of Grok 4 has not been without controversy. Recently, Grok has faced widespread criticism for generating inappropriate content (such as "MechaHitler"), raising ethical questions about AI outputs. Additionally, X's CEO Linda Yaccarino resigned due to the negative impact associated with Grok, further intensifying concerns over the regulation and ethical framework of xAI. Nevertheless, xAI continues to roll out new features, including a high-performance subscription tier named SuperGrok Heavy, which offers advanced reasoning, coding tools, and priority support. While it has not yet been confirmed whether full API access will be provided, some endpoints are already live, and broader access is expected soon.
