Musk: Grok 4.20 will be released in about three weeks, and Grok 5 will be released a few months later.

On December 10, Elon Musk stated that Grok 4.20 will be released in about three weeks, while Grok 5 will be launched in a few months. Grok 4.20 is a major update to xAI’s fourth-generation Grok series AI model. It made its debut as a “mystery model” on testing platforms such as Alpha Arena, where it performed exceptionally well in stock trading simulations, achieving an average return rate of 12.11% (with a maximum of 47%). The model demonstrated significant improvements in real-time data analysis, financial reasoning, and complex problem solving. Grok 5 is xAI’s next-generation flagship AI model, aiming to achieve breakthroughs at the Artificial General Intelligence (AGI) level, with a parameter scale of 6 trillion (twice that of Grok 4). Musk estimates the probability of achieving AGI at 10% and rising, and the model will feature “instant learning” capabilities, allowing it to quickly adapt to new tasks through dynamic reinforcement learning.
