In September 2025, a Chinese state-sponsored hacking group reportedly used Claude Code (an AI programming assistant created by Anthropic) to carry out a large-scale espionage operation against roughly 30 global targets, including major tech companies, financial institutions, chemical manufacturers, and government agencies. Unlike previous AI-assisted attacks, the attackers built an automated framework around Claude Code so that the AI could handle 80–90% of the tactical work: scanning networks, finding vulnerabilities, writing exploit code, testing stolen credentials, and pulling down data. Humans mostly popped in at a few key checkpoints to approve big moves like exploitation and data exfiltration. This is believed to be the first documented case of an AI autonomously executing such […]

We now have AI that can drive a real web browser to complete tasks, process up to ~1 million tokens in a single prompt, and propose code changes that pass tests on real repos. This guide cuts through the noise of press releases and benchmarks to deliver a clear, no-nonsense comparison based on real-world performance. We’ve synthesized the latest data from sources like The Verge, Axios, and the developers themselves to help you make an informed decision. Which AI model truly wins in October 2025? Is GPT-5 better than Gemini 2.5 for your daily work? And what is the absolute best LLM for coding, creative writing, or deep research right […]

2025年9月29日、Anthropicは最新のフロンティアAIモデルであるClaude Sonnet 4.5をリリースし、同社がこれまでに開発したモデルの中で最も能力が高く、最も整合性のあるモデルと位置づけた。このリリースは、これまでのクロード・ソネットとオーパスのリリースの基礎の上に構築されており、持続的な自律パフォーマンス、コーディング能力、ツールの使用、安全行動の測定可能な改善に焦点を当てています。Anthropicは、2ヶ月弱の社内テストの後、API、Amazon Bedrock、Google Vertex AIにおいてClaude Sonnet 4.5を本番稼動させました。 このモデルは現在、Claude.aiとAPIアクセスを通じてすべてのユーザーが利用可能で、間もなくFello AIに統合される予定です。その内容を詳しく見てみよう。

人の反AI活動家が現在、大手AI企業本社の前で10日以上にわたるハンストを行っている。ギド・ライヒスタッターはAnthropic社のオフィスの外で、マイケル・トラッツィはDeepMind社で抗議活動をしている。両者とも、人工知能への道は人類に存亡の危機をもたらすと主張している。彼らの主張によれば、AI企業は世界中の家族や子供たちに危害を加えかねない危険な領域に向かって突き進んでいるという。この抗議行動は、現在のAI開発は無謀であり、破滅的な事態を招きかねないと考える人々の、大きくなりつつあるがまだ小さな運動を代表するものである。ライヒスタッターは2児の父であり、以前は28時間にわたって橋の上で抗議活動を行った。

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。

On August 5th, 2025, Anthropic released Claude Opus 4.1, which quietly climbed to the top of the rankings. Though the model didn’t get any over-hyped marketing campaigns, today, it sits at the top of LMArena’s leaderboard across all domains. LMArena is a platform where thousands of users compare AI models in blind tests to determine which ones actually perform better in real-world scenarios. Based on the rankings Claude Opus 4.1 consistently outperforms competitors when people test it without knowing which model they’re using. Claude Opus 4.1 is a highly capable AI model across multiple use cases, though it’s worth setting expectations properly – this isn’t a revolutionary breakthrough that changes […]

More and more people are asking the same question – what actually is the best AI chatbot? With new AI models launching constantly and each company claiming theirs is the breakthrough everyone’s been waiting for, getting a straight answer feels harder and harder. Most “best of” lists online are either outdated, biased, or based on someone’s personal opinion rather than actual data. But we might finally have a clear answer. A recent study by Onelittleweb analyzed over 10,500 AI tools and nearly 100 billion web visits to figure out which chatbots are actually winning. Instead of relying on marketing claims or gut feelings, the study focused on real metrics – […]

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 […]

For most people, AI already feels like a revolution. Tools like ChatGPT, Midjourney, and Grok can write emails, build apps, and generate entire videos – tasks that would’ve taken entire teams just a few years ago. But for the CEOs building these technologies, what we’ve seen so far is just the beginning. Nearly 78,000 tech jobs were cut between January and June 2025, many directly tied to AI-driven automation in giants like Amazon and Microsoft. And according to a recent World Economic Forum report, 41% of employers worldwide now plan to reduce their workforce because of AI. CEOs at the helm of companies like Anthropic, Nvidia, and Google have begun […]
