ChatGPT now runs on GPT-5.4, launched on March 5, 2026, while Grok is powered by Grok 4.20 from xAI. Both chatbots have evolved significantly over the past year, and picking between them is no longer as simple as “ChatGPT is the default.” Grok has grown from 1.9% US market share to 17.8% in just 12 months, while ChatGPT still dominates with over 900 million weekly active users and roughly 64.5% global market share. So which one should you actually use? We compared Grok vs ChatGPT across benchmarks, pricing, coding, writing, real-time capabilities, and more. Here is what the data shows, and clear recommendations based on what you need an AI […]

Today, November 17, 2025, xAI has officially rolled out Grok 4.1, the latest iteration of its flagship large language model, across grok.com, the 𝕏 interface, and the iOS and Android apps. The update arrives after a two-week silent production test and aims to deliver more natural conversation, stronger emotional intelligence, tighter safety controls, and dramatically improved real-world reliability. Unlike typical incremental updates, Grok 4.1 represents a noticeable shift in how xAI tunes and deploys its models: it introduces deeper reinforcement learning on style, personality, and alignment, while preserving the factual accuracy and reasoning depth Grok 4 was known for. Below is everything you need to know — benchmarks, new capabilities, safety upgrades, and how […]

今週のOpenRouterのランキングを開いた人は、最初の2つの枠に見慣れないロゴがあるのを見ただろう：Grok 4 Fast（無料）とxAIのGrok Code Fast 1だ。xAIのGrok 4 Fast（無料）とGrok Code Fast 1だ。この2つを合わせると、マーケットプレイスを経由する全トークンの3分の1以上を占めることになる。両者を合わせると、xAIはGoogle、Anthropic、OpenAIをも凌駕し、市場全体のシェアで#1のポジションに押し上げた。しかし、比較的若いモデルがどのようにして巨人を追い越したのだろうか？また、Grok 4 Fastが開発者、新興企業、企業チームの間でこれほど人気があるのはなぜだろうか？強力なパワー、お買い得な価格設定、そして期間限定の無料エンドポイントの組み合わせは、Grok 4 Fastを多くのビルダーのデフォルトの選択肢に変えました。以下はその詳細です。

最も勢いのあるAI企業5社がそれぞれのフラッグシップモデルを発表し、人工知能開発においてこれまでに見たことのないような熾烈な競争が繰り広げられている。OpenAIは2025年8月初旬にGPT-5を発表し、Anthropicはその数日前にClaude Opus 4.1をリリースした。グーグル・ディープマインドのGemini 2.5 Proは3月下旬に登場し、xAIは7月にGrok 4を発表、そして今回アリババが9月上旬にQwen 3 Maxでゲームに参入した。しかし、これらは実際に大きな進歩なのだろうか、それともささやかな改良をマーケティングに利用しただけなのだろうか？どの企業も、自社のAIを最もインテリジェントで有能なアシスタントだと宣伝し、そのモデルを示す厳選されたベンチマークや洗練されたデモに裏打ちされている。

AI benchmarks are usually abstract. They test math puzzles, programming problems, or reading comprehension tasks most people never encounter in real life. But the newest yardstick for long-term AI performance is surprisingly ordinary: running a vending machine. The benchmark, called Vending-Bench, was created by Andon Labs to test whether AI agents can handle one of their hardest unsolved problems — staying coherent and effective over long stretches of time. Each agent is tasked with operating a simulated vending machine business: tracking inventory, placing orders, setting prices, collecting revenue, and paying daily fees. On paper, these are trivial management chores. In practice, they push models to their limits when extended across 20 million […]

2025 has been an amazing year for AI, with new models landing almost every month—and it’s not slowing down yet. The biggest labs all have something in the pipeline: Google’s DeepMind, OpenAI, Anthropic, xAI, and DeepSeek are lining up their next releases. Most will be more about steady progress than big breakthroughs, but they’re still key steps in the race toward more general AI. Google is gearing up for Gemini 3.0, Anthropic keeps rolling out Claude upgrades, xAI has Grok 5 on the way, and DeepSeek is trying to get V4 and R2 out despite chip problems in China. OpenAI, after the backlash around GPT-5, is already working on GPT-5.5 […]

The 4 biggest players in the AI space have all released their latest flagship models, marking what might be the most competitive moment in artificial intelligence history yet. Google DeepMind launched Gemini 2.5 Pro in late March 2025, followed by xAI‘s Grok 4 in early July, while Anthropic unveiled Claude Opus 4.1 just days before OpenAI finally delivered the highly anticipated GPT-5 in early August 2025. Each company promises revolutionary capabilities that will transform how we work and create. But do these models actually live up to the marketing hype, or are we looking at incremental improvements dressed up as breakthroughs? Each company claims their model is the smartest and […]

The brand new Grok 4 from xAI was built to be bold. Marketed as Elon Musk‘s alternative to generic AI, it’s fast, web-connected, and trained with an edge. But that edge sometimes cuts too deep. Since its release, Grok 4 has stirred up controversy after controversy, ranging from bizarre identity claims to political hot takes and troubling safety concerns. Unlike other models that aim to stay neutral and polished, Grok 4 prides itself on being raw, “opinionated”, and more “human-like” in tone. But when you let an AI roam freely across the web and respond without traditional filters, you also open the door to unexpected outcomes. Depending on who you […]

With Grok 4, you can do far more than just chat. You can now build full-blown products, apps, and games — even if you’ve never written a single line of code. That’s because xAI equipped the model with powerful reasoning, long-context understanding, and coding capabilities designed specifically for real-world use. In fact, Grok 4 scored 79.3% on the LCB benchmark (Jan–May), which tests how well large language models can write and understand long, complex codebases. That puts it among the best models in the world for building actual working apps, not just snippets or toy projects. Whether you’re exploring side hustles, building tools for fun, or chasing your first product […]

Choosing the right AI assistant in 2025 goes beyond brand hype — it comes down to what the model can actually do. Whether you’re coding, writing, solving complex problems, or just chatting, four AI models dominate the conversation: Grok 4, ChatGPT-4o, Claude Opus 4, and Gemini 2.5 Pro. Each excels in different areas — one leads in deep reasoning, another in natural conversation, and others in creativity or multimodal capabilities. In the past year, AI development turned into an actual race. Each company released their answer to GPT-4o, which had over a year’s head start. Anthropic launched Claude Opus 4 in May 2025, Google DeepMind followed with Gemini 2.5 Pro in June, and xAI dropped Grok 4 in […]
