With a 73 Intelligence Index (beating O3's 71)[5], and top scores on graduate-level reasoning and math problems†, xAI's latest model establishes new state-of-the-art benchmarks. But with Cloudflare's new "Pay Per Crawl" system[12] and ballooning energy demands, the real question isn't just how good Grok-4 is—it's whether the industry can afford the monetary and environmental price of progress. †Community-reported scores (AIME 95%, GPQA 88%) are not yet confirmed by benchmark organizations. The Benchmark Revolution: Grok-4's Commanding Performance On July 10, 2025, xAI quietly released Grok-4, skipping the expected 3.5 version and going straight to what Elon Musk called "the big run."[18] Within 48 hours, the AI community was buzzing about benchmark results that nobody saw coming. The numbers tell a story of decisive leadership across multiple AI domains:

‡ Community-reported score, pending official verification.

Verified metrics: Intelligence Index (73) and MMLU-Pro (86.6%, displayed as 87%) are confirmed by Artificial Analysis.[5][6]
Awaiting confirmation: AIME 95%[8], GPQA 88%[7], SWE-Bench 75%[9], and HLE 45%[10] are reported in community leaks and benchmark threads but not yet verified by independent testing organizations. These figures should be considered preliminary until confirmed by official benchmark maintainers. What makes these numbers remarkable isn't just the absolute performance—it's the breadth of dominance. Grok-4 doesn't just excel in one area; it leads across reasoning, mathematics, physics, and coding. The 95% AIME score, while still pending official verification, is particularly striking, representing a 6+ point lead over O3 on problems that typically stump even graduate students.[8] Grok-4's documented context window is 256k tokens for paid API users, with a lighter 128k-token tier powering the free X Premium+ experience.[13] A rumored 1M-token 'Heavy' variant exists only in internal demos so far—the 1M figure was a Grok-3 aspiration that hasn't shipped publicly. Note on Gemini 2.5 Pro: Currently supports 1M tokens, with 2M tokens announced but not yet generally available. But the real story isn't just about raw performance—it's about the architectural philosophy behind these gains. The Physics of AI: How Grok-4 "Thinks Like a Physicist" xAI describes Grok-4 as explicitly architected to "think like a physicist," decomposing problems to fundamental axioms before forward-chaining a solution.[2][15] This first-principles reasoning approach shows up most dramatically in its outsized gains on GPQA (graduate-level physics) and the notoriously trick-proof Humanity's Last Exam. First-principles thinking involves breaking down complex problems into their most fundamental components and building solutions from the ground up. Instead of reasoning by analogy (comparing to what we've seen before), it questions basic assumptions and derives solutions from core truths. In AI context: Grok-4 appears to decompose problems into axioms first, then systematically build toward solutions rather than pattern-matching against training data. This approach shows particularly strong results on novel problems that can't be solved through memorization. The architectural changes supporting this approach are significant, though details like parameter count and Mixture-of-Experts (MoE) depth remain unconfirmed by xAI and are based on community leaks and insider reports.[14] This architectural shift explains why Grok-4 excels particularly...
