Elon Musk’s company, xAI, released ‘Grok 4’, its latest model, last week, in response to OpenAI’s GPT-5, which is expected to be released in September. This model, which can analyze images and respond to questions, is deeply integrated into the X social platform.
“With respect to academic questions, Grok 4 is better than PhD level in every subject, and at times, it may lack common sense, and it has not yet invented new technologies or discovered new physics, but that is just a matter of time,” said Elon Musk. [See the product video presentation below.]
xAI also unveiled a new $300-per-month AI subscription plan, SuperGrok Heavy, the company’s multi-agent version that offers increased performance.
The plan is similar to ultra-premium tiers offered by OpenAI, Google, and Anthropic.
Musk claimed that Grok 4 Heavy spawns multiple agents to work on a problem simultaneously, and then they all compare their work “like a study group” to find the best answer.
The company ensured that Grok 4 — also released through its API — demonstrates frontier-level performance on several benchmarks, including Humanity’s Last Exam. Grok 4 scored 25.4% on Humanity’s Last Exam without “tools,” outperforming Google’s Gemini 2.5 Pro, which scored 21.6%, and OpenAI’s o3 (high), which scored 21%.
With “tools,” Grok 4 Heavy was able to achieve a score of 44.4%, outperforming Gemini 2.5 Pro with tools, which scored 26.9%, according to the company.
xAI announced that its AI coding model will be available in August, a multi-modal agent in September, and a video-generation model in October.
