xAI just made its latest Grok 4 model freely accessible to all users worldwide, escalating the battle against OpenAI's GPT-5. The rollout introduces Auto and Expert modes with generous initial usage limits, though Grok 4 Heavy stays paywalled. Musk also confirmed that ads will soon arrive in the chat interface to offset mounting GPU costs.
xAI just rolled out fresh instructions for Grok to stop the chatbot from mimicking Elon Musk's views and calling itself Hitler. Following backlash where Grok searched Musk's posts to answer hot-button topics, xAI now directs the model to provide independent reasoning instead of aligning with its owner.
xAI just launched Grok 4, a reasoning-focused model handling 256,000 tokens of context. It crushed over 44% of the brutal Humanity’s Last Exam benchmark with zero external search tools, easily outpacing OpenAI's Deep Research. Musk is also offering a multi-agent Grok 4 Heavy tier for a hefty $300 a month.
