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 […]

New research reveals that even the most popular AI models can’t be trusted when it comes to basic safety. The most powerful LLMs today — including models from OpenAI, Google, and Cohere — were put through a rigorous safety benchmark. The results? Not great. Out of 20 models tested across 10 real-world risk areas, none passed all the tests, and 76% failed one of the most basic challenges: impersonation and privacy violations. If you’re building with AI or using it in your product, this should make you pause. Because once something goes wrong, you’re the one holding the bag — not the model provider. The Aymara Matrix: Safety Benchmark for LLMs The research comes […]

Advanced AI chatbot assistants like Google’s Gemini offer powerful capabilities — from summarizing emails to helping you brainstorm, write, and research faster. But behind the convenience lies deep integration with your Google identity and broader activity history. And because Gemini often feels like a helpful, judgment-free partner, always available and eager to assist, it’s easy to start oversharing. Many users end up typing out private thoughts, sensitive work information, or even confidential documents without questioning it. That sense of safety can be misleading. While Google states that your chats aren’t used for training unless you give explicit consent, your prompts are stored in your account by default. These chats can […]

AI競争がかつてないほど過熱している。2025年5月現在、OpenAI、Anthropic、Google、xAIはいずれも最新のフラッグシップモデル、ChatGPT（GPT-4.5/4.1）、Claude 4（Claude 3.7 Sonnet）、Gemini 2.5 Pro、Grok 3を発表している。それぞれが、知能、創造性、推論、道具の使用における大きな飛躍を約束しており、今回の誇大宣伝は単なるマーケティングではない。これらのモデルは純粋により便利で、より有能で、多くの場合、衝撃的なほど優れている。しかし、疑問が残る。どれが実際にベストなのだろうか？答えは、あなたが何を求めているかによる。コーディングや技術的な作業を得意とするものもあれば、会話やリアルタイムの知識、巨大なドキュメントを扱うことを得意とするものもある。はっきりしているのは、私たちはついに[...]を手に入れたということだ。

Google I/Oは常に、いつか製品になるかもしれない研究開発プロジェクトのショーケースだった。2025年版はそれとは異なっていた。ライトフィールドのビデオブースであれ、メガネであれ、刷新された検索ページであれ、ほとんどすべてのデモが同じ脳幹で動いていた：Gemini 2.5である。基調講演のメッセージは明確だった。グーグルの未来は「AIを搭載した」アプリではなく、すべてを動かす1つのAIプラットフォームなのだ。以下は、重要な発表を深く掘り下げ、ステージに到着した順番にばらばらにするのではなく、一つの物語にまとめたものである。Gemini Everywhere I/Oの他の部分は、モデルのニュースなしには理解できないだろう。グーグルはGemini 2.5 Proを発表した。

The way we search the internet is undergoing a profound shift. For over two decades, Google has defined how we retrieve information: a search bar, a list of links, and a web of results filtered through a ranking algorithm that’s constantly evolving. But in the past year, a new contender has started drawing serious attention: Perplexity AI. Built as a conversational, citation-powered search assistant, Perplexity aims to streamline research, eliminate SEO spam, and provide real-time answers with sources embedded directly in its summaries. With AI-first experiences gaining traction and traditional search engines facing criticism for declining result quality, the question for users is clear: should you stick with Google or give […]

Stop guessing. Start working smarter. With so many AI models available today, choosing the right one can be overwhelming. Most people default to just one model—usually ChatGPT—and use it for everything. While that works okay, it’s far from optimal. Each model has its own strengths. Some are better at math, others at writing, others at real-time research. Knowing which tool to use for the task at hand can make a big difference in speed, accuracy, and quality of results. Here’s a simple breakdown of the top AI models in 2025—what they’re good at, how to use them, and when to pick one over the others. 1. ChatGPT – Best for Advice, […]

Just a few days after its official debut on March 25, 2025, Google has once again redefined the boundaries of artificial intelligence with the launch of Gemini 2.5. Hailed as the company’s most advanced and “intelligent” AI model to date, Gemini 2.5 is not just an incremental upgrade—it represents a radical shift in the way AI reasons, codes, and comprehends complex data. The new model, branded as Gemini 2.5 Pro Experimental, has quickly risen to the top of the LMArena leaderboard with a striking Arena Score of 1,443, surpassing xAI’s Grok 3 Preview (1,409) and OpenAI’s GPT-4.5 (1,395). Its high vote count and strong confidence interval underscore widespread agreement that Gemini […]

2025年1月、中国の新興企業ディープシーク（DeepSeek）がAIモデル「R1」を発表し、瞬く間にChatGPTを抜いて米国のiOSアプリストアで最もダウンロードされた無料アプリとなった。 この快進撃は、AI業界を混乱に陥れただけでなく、世界のハイテク市場に衝撃を与え、業界大手各社の株価を大きく変動させた。この勢いに乗って、つい先週、イーロン・マスクのAIベンチャーであるxAIは、既存のAIの巨人に挑戦することを目的としたGrok 3を発表した。その中で [...]...
