Elon Musk’s AI company xAI is introducing Grok 4.0, weeks following the last model, Grok 3.0, which gained news attention after it sent antisemitic messages on social media platforms. The company is describing this new chatbot as a breakthrough in AI conversational tech — one that has been dubbed ‘Big Bang Intelligence’ by Musk.
The timing is notable here, coming soon after the surprise resignation of X (formerly Twitter) CEO Linda Yaccarino. There has been no official link between the two, but the proximity of events has sparked rumors in tech circles.
Why It Matters
It was in June 2025 that Grok 3.0 became the news for generating hate speech, such as admiration for Adolf Hitler. The outrage came quickly, with xAI deleting the posts, suspending public engagement of Grok, and vowing to enhance its content moderation.
Public debate regarding AI responsibility has intensified in recent months. A 2025 survey conducted by the Pew Research Center discovered that 74% of Americans want to make AI firms legally accountable for poisonous content produced by their algorithms.
xAI maintains Grok 4.0 has significantly improved on moderation, conversational sensitivity, and ethical safeguards against a repeat of previous failure.
What’s New in Grok 4.0
Elon Musk described the new chatbot as…
“Our Big Bang moment for AI – not smarter, just more contextually aware, funny, and human in its nuance.”
As xAI describes, Grok 4.0 offers faster, acuter, and safer conversations that are more capable of handling sensitive topics as well as nuances of conversation, glaring omissions of prior versions.
The latest AI is already available to X premium members, and a global public release is planned at some point in late July 2025. xAI is implementing releases of Grok 4.0 in phases to closely observe performance and user response before expanding globally.
AI Experts Weigh In Grok 4.0
This is what an expert had to say:
AI ethics experts have voiced concerns about the pace of conversational AI development. Industry analysts say the Grok controversy highlights the risks of deploying powerful chatbots without strict oversight, reinforcing calls for tighter content safety frameworks.
