In the space of 48 hours, Anthropic announced a $900 billion valuation round, acquired a company that builds the infrastructure for its rivals, and topped CNBC's Disruptor 50. Meanwhile a jury threw out Elon Musk's lawsuit against OpenAI in under two hours. And Google I/O launched its most AI-dense keynote ever. Here is everything that happened this week.

Google's I/O 2026 keynote delivered its most AI-dense announcement slate ever. Gemini Spark is a 24/7 personal agent that runs on your behalf while your laptop is closed. Gemini 3.5 Flash outperforms the previous flagship model at four times the speed. And AI Ultra just dropped to $100 a month. Here is everything that was announced, explained.

Four in five university students now use AI tools for their coursework, according to the Stanford AI Index 2026. Most are using the wrong ones for what they actually need. This guide organises the best student AI tools by the specific problem they solve — not by which ones have the most impressive marketing.

A paper published at NeurIPS 2025 by Google Research researchers introduces "Nested Learning" — a new paradigm that argues the boundary between a model's architecture and its training algorithm is an illusion. This article breaks down what the paper actually says, what it means for current transformer-based AI tools, whether it will change how you use them, and what the honest limitations are.

A research team at Tsinghua University has built a foundation model trained on 12 billion candlestick records from 45 global exchanges. It outperforms every previous approach on price forecasting and volatility prediction. Here is what it is, what it genuinely can and cannot do, and why the broader trend it represents matters more than the model itself.

The average knowledge worker now saves between five and ten hours per week using AI tools — but most people are using the wrong ones for their actual bottlenecks. This guide cuts through the noise and matches the best AI productivity tools to the specific problems they actually solve.

On February 23, 2026, 38 researchers from Harvard, MIT, Stanford, Carnegie Mellon and nine other institutions published a paper that should be required reading for anyone building, deploying or regulating autonomous AI systems. This is everything it found, everything it means, and why it matters more than the headlines captured.

NotebookLM is not a chatbot. It does not search the internet. It does not guess. It reads your documents and answers from them — with citations pointing to the exact passage it drew from. This complete guide covers every feature, every real-world use case, and exactly who it is worth paying for.

More than half of UK small businesses are now actively using AI tools — up from just 25% two years ago. But knowing which tools are actually worth paying for is a different question entirely. This guide covers the tools that deliver measurable results across marketing, admin, automation, and customer management, with honest assessments of cost, limitations, and who each tool is best suited for.

Anthropic released Claude Opus 4.7 on 16 April 2026, replacing Opus 4.6 as its most capable publicly available model. The update brings major gains in agentic coding, a new high-resolution vision system, three new developer features, and a set of breaking API changes that caught some teams off guard. Here's the complete picture.

A peer-reviewed study from Hugging Face researchers, presented at NeurIPS 2025, has put hard numbers on what generating AI video actually costs in energy. The findings reveal costs that are orders of magnitude higher than text or image generation — and a scaling problem that gets dramatically worse as resolution and video length increase.

Three years after the AI chatbot wars began, there is still no single winner — but there are clear answers depending on what you actually need. This article compares Google Gemini, OpenAI's ChatGPT, and Anthropic's Claude across writing, coding, research, pricing, and real-world use cases so you can stop guessing and start choosing.
