TL;DR: You cannot remove data from AI models that have already been trained, but you can stop companies from using your future chats to improve them. ChatGPT, Claude, and Gemini all provide specific toggles to opt out of training, though they may still keep logs for a limited time for safety and legal reasons. AI Assistant Default Training Status How to Stop It Best for Privacy ChatGPT ON by default (Consumer plans) Settings > Data Controls > Turn off “Improve the model” Use Temporary Chat Claude ON (Changed late 2025) Settings > Privacy > Turn off “Help improve Claude” Use Incognito mode Gemini ON (Keep Activity default) Profile > Gemini […]

TL;DR: A 2025 study suggests that being rude or curt to ChatGPT-4o can slightly improve accuracy (by ~4%) on multiple-choice questions. However, this is likely because rude prompts are shorter and more direct, not because the AI likes the attitude. You can get the same results by being concise without being mean. Metric Details Study Name Mind Your Tone (Dobariya & Kumar, 2025) Model Tested ChatGPT-4o Accuracy Gap Very Polite (80.8%) vs. Very Rude (84.8%) Main Driver Directness, brevity, and lack of “social fluff” Recommended Strategy Be direct and structured (neutral), not abusive. We have been told to treat AI chatbots like polite colleagues. Saying “please” and “thank you” to […]

November 24, 2025. Anthropic has officially launched Claude Opus 4.5, a major refresh of its top-tier model and the company’s strongest push yet in the fight for AI leadership. Coming just days after Google’s Gemini 3 debut, the new Opus arrives with a sharp focus on professional coding, long-running agents, and desk-work automation—and Anthropic is backing the launch with aggressive pricing and hard benchmark data. The company says Opus 4.5 is now the leading model for real-world software engineering, slide and spreadsheet editing, and multi-step agentic workflows. Early numbers support the claim, with the model showing large performance gains across enterprise tasks. And in a move aimed at accelerating adoption, Anthropic has cut Opus […]

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 […]

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。

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 […]

Another school year is starting, and you’re probably already imagining that long list of classes, assignments, and deadlines that need to be managed. Between juggling lecture notes, group projects, calendar scheduling, and research papers, staying organized can feel overwhelming before you’ve even attended your first class. The difference between students who excel and those who struggle often comes down to having the right digital tools that actually save time instead of creating more complication. The good news is that your Mac can become exactly that, you’ve just got to have the right apps. Tools that can capture and organize every piece of information you encounter, manage your schedule with simply […]

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 […]
