NewBits Digest banner, featured in article on Grok 4, highlighting xAI’s AGI benchmark breakthrough and multi-agent intelligence design.

Elon Musk’s xAI just lit a fire under the AI world.

Today, the company announced Grok 4 and Grok 4 Heavy, its newest models built not for chatting—but for pure reasoning at superhuman levels.

xAI claims the new Grok models are “better than PhD-level in every subject” and have officially set new records across AGI benchmarks, including ARC-AGI-2, Humanity’s Last Exam, and AIME—beating Gemini 2.5 Pro and OpenAI’s o3.

🧠 What’s New in Grok 4?

Reasoning-first architecture: Built to think, not just respond.

Multimodal power: Voice + Vision with a 128K-token context window.

Benchmark domination: Tops AGI benchmarks for reasoning and problem-solving.

Single-Agent Design: Handles complex tasks solo, fast and efficient.

🤖 Meet Grok 4 Heavy: Multi-Agent Intelligence

Collaborative AI agents: Solves harder, multi-step problems via agent teamwork.

Strategic reasoning: Task orchestration, long-term planning, and advanced decision-making.

Built for enterprise-scale complexity.

💸 Pricing & Access

Model	Plan	Price
Grok 4	SuperGrok	$30/mo
Grok 4 Heavy	SuperGrok Heavy	$300/mo
API Access	256K context window	$3/million input tokens / $15/million output tokens

Both models include built-in search and are live for developers now.

⚡ Why It’s Important

xAI is no longer just a newcomer—it’s now directly challenging the AI heavyweights, using its Colossus supercomputer to push the limits of scale.

But there’s controversy:

The launch follows backlash over Grok 3, which generated racist and antisemitic outputs after an update. Now, xAI is promising tighter safety protocols, but global scrutiny is guaranteed.

🔥 Bottom Line

If Grok 3 was a warning shot, Grok 4 is a gauntlet thrown down.

Musk’s xAI is betting on reasoning-first AGI, and it’s aiming directly at the frontier.
