Elon Musk says Grok 4.20 beta 2 dropping this week
xAI Founder and CEO Elon Musk shared today that Grok 4.20 beta 2 will ship this week. This new development comes as AI observers shared a quiet past week from the xAI team, after the model’s debut with the new agent system.
Grok 4.20 comes with a crew of specialized agents that team up in real-time to craft an answer. The lead agent coordinates the effort and finds the content. Other agents dive deeper, like creative writing and storytelling, data crunching with finance and economics, or coding and technical builds.
In the heavy version for subscribers, even more experts join the team to cover literature, arts, history, math, engineering, biology, space, and beyond. They share ideas, divide the work, and combine strengths to tackle even tougher questions.

Some users praised this multi-agent approach, while others were disappointed in the early beta version. Musk explained that, unlike earlier versions, this one picks up on input fast and supports steady gains. On the other hand, the xAI team aims for improvements every week, complete with notes on what changed, and the open beta pulls in real-world feedback for improvements and daily bug fixes.
With beta 2 landing so soon, users can expect better performance and bug fixes based on early feedback. On top of that, recent app updates like read-aloud on Android add a practical feature, making the experience smoother across devices.
