xAI launches Grok 4 alongside premium subscription tier 'SuperGrok Heavy'
Elon Musk’s AI company, xAI, made headlines on Wednesday with the launch of its latest flagship AI model, Grok 4, alongside a premium subscription offering called SuperGrok Heavy, priced at $300 per month.
Grok, which serves as xAI’s answer to AI models such as OpenAI’s ChatGPT and Google’s Gemini, boasts enhanced capabilities, including the ability to analyse images and respond to a wide range of queries.
Despite its integration into Musk’s social media platform, X, Grok has recently been under scrutiny for some controversial remarks that led to xAI limiting the chatbot’s features.

The introduction of Grok 4 comes as high expectations mount for its performance, particularly with OpenAI’s GPT-5 on the horizon.
According to Musk, Grok 4’s academic abilities are “better than PhD level in every subject,” although he acknowledges that the AI model has yet to make major breakthroughs in technology or physics.
Following a rocky week for Musk’s companies, including the resignation of X’s CEO Linda Yaccarino, the launch has placed Grok’s capabilities in the spotlight, overshadowing earlier issues with the AI's online behaviour.
Musk was present with xAI leadership during the launch event.
Grok 4 scored highly on several academic benchmarks, outpacing Google’s Gemini and OpenAI’s o3, demonstrating its potential for research and development purposes.
Along with Grok 4, xAI introduced Grok 4 Heavy, a more advanced version designed for increased performance.
The new subscription plan, SuperGrok Heavy, offers exclusive access to this model, with the promise of future releases such as an AI coding model and a video generation model.

This is what everyone @xAI does. Works better than Cursor.However, xAI’s aggressive pricing and recent controversy over Grok’s behaviour could challenge its ability to position Grok as a serious competitor in the AI space.
With plans to expand into enterprise applications, xAI is aiming to secure a foothold in the business world—though the model’s past mishaps may complicate its broader adoption.
