In a highly anticipated livestream on July 9, 2025, hosted on xAI’s official X account (@xAI), Elon Musk and the xAI team introduced Grok 4, dubbed “the world’s most powerful AI assistant.” The event, which kicked off over an hour late at 8 PM Pacific Time (8:30 AM IST), drew over 1.5 million viewers at its peak, marking a significant milestone in the global AI race.Grok 4: A Leap Forward in AI InnovationGrok 4, designed to rival OpenAI’s GPT-4o and Google’s Gemini, comes in two variants:Grok 4 (Generalist Model): Tailored for everyday users, it excels in tasks like writing, research, translation, and advanced logical reasoning. It also tackles complex mathematical and scientific queries with unprecedented accuracy.
Grok 4 Code: A developer-focused version integrated with tools like the Cursor editor, offering robust code generation, bug detection, and contextual software development support.
Unmatched PerformanceGrok 4 sets new benchmarks in AI performance:Scored 45% on Humanity’s Last Exam (text-only subset), surpassing Gemini 2.5 Pro (21%) and OpenAI’s models in Deep Research mode (25%).
Achieved 95% accuracy on AIME 2025 (math) and 88% on GPQA (PhD-level science).
Recorded an Artificial Analysis Intelligence Index of 73, outpacing OpenAI’s o3 (70) and Anthropic’s Claude 4 Opus (64).
The AI boasts a 256k token context window, supports text and image inputs, and is poised to add vision, image generation, and multimodal capabilities. A specialized multi-agent version, Grok 4 Heavy, scored an impressive 50.7% on Humanity’s Last Exam, leveraging enhanced test-time compute.Availability and PricingGrok 4 is initially accessible via xAI’s API, with potential integration into Microsoft Azure AI Foundry. Pricing is set at $3/$15 per 1M input/output tokens, competitive with Anthropic’s Claude 4 Sonnet but higher than Gemini 2.5 Pro. Access on X is likely limited to Premium and Premium+ subscribers, following the model of Grok 3. The AI delivers 75 tokens/s, slower than OpenAI’s o3 (188 tokens/s) but faster than Claude 4 Opus (66 tokens/s).Musk’s Vision and Future PlansElon Musk emphasized Grok 4’s “maximally truth-seeking” approach, addressing prior criticisms of AI bias. He hinted at ambitious future applications, including Grok 4 potentially discovering new technologies by 2026 and powering AI-driven AAA game development next year.A Rocky Launch Amid ControversyThe launch follows a recent controversy where Grok made inappropriate remarks praising Hitler in response to queries about “anti-white hate,” prompting xAI to ban hate speech in its responses. Despite the hiccup, the livestream generated massive buzz, with X users praising Grok 4’s coding and reasoning prowess, though some criticized the event’s delay and Musk’s presentation style.Why It MattersxAI’s decision to skip Grok 3.5 and unveil Grok 4 underscores its aggressive push to lead the AI industry. With OpenAI’s GPT-5 still under wraps, Grok 4 positions xAI as a formidable contender in the race for AI supremacy.The livestream is available for replay on xAI’s X handle (@xAI).
