Pulitzer Prize winner John Carreyrou and other authors are suing OpenAI, Anthropic, Google, Meta, xAI, and Perplexity for book piracy. The AI companies allegedly stole their works from illegal online libraries. The lawsuit has a strong case, and this time the plaintiffs are going after the big bucks instead of the “pennies” of a class action settlement.
A comprehensive collection of "Claude Skills" is now available on GitHub. These skills are customizable workflows that teach Anthropic's AI assistant Claude to perform specific tasks repeatedly and in a standardized way. The collection includes more than 50 skills across nine categories: Document Processing (Word, PDF, PowerPoint), Development Tools (Playwright, AWS, Git), Data Analysis, Business and Marketing, Communication, Creative Media, Productivity, Project Management, and Security.
Users can add skills in Claude.ai through the settings, store them in Claude Code's configuration folder, or integrate them via API. Each skill consists of a folder with a SKILL.md file. The repository is under Apache 2.0 license and accepts contributions.
Since skills are essentially just a collection of prompts in a folder, getting the most out of AI means customizing these prompts to fit your needs. That said, the repository is a solid source of inspiration. And as skills seem to be becoming the standard approach, it's worth exploring the topic beyond Claude.ai.
OpenAI is using automated red teaming to fight prompt injections in ChatGPT Atlas. The company compares the problem to online fraud against humans, a framing that downplays a technical flaw that could slow the rise of the agentic web.
GPT-5 solves an open math problem for the first time, and the mathematician behind it shows exactly which line came from which AI. Does science really need this level of transparency?
Google is ramping up its AI infrastructure with a major energy acquisition. Parent company Alphabet is buying clean energy developer Intersect for $4.75 billion in cash, plus assumed debt.
Alphabet is acquiring Intersect's energy and data center projects that are currently under development or construction. The company holds assets worth $15 billion. By 2028, projects with roughly 10.8 gigawatts of capacity should be online—more than twenty times the electricity output of the Hoover Dam, as Reuters reports. Intersect will continue to operate separately from Alphabet. Existing plants in Texas and California aren't part of the deal.
The deal reflects a broader trend: big tech companies are pouring money into energy assets as US power grids struggle to keep pace with soaring electricity demand from artificial intelligence. Google says it plans to double its AI capacity every six months, aiming for a thousandfold increase in output within four to five years. To hit those targets, Google is also investing in advanced reactor technology.
OpenAI has reportedly made major strides in improving the profitability of its AI services. The company's compute margin—the share of revenue left after paying for server costs from paying users—jumped from around 35 percent in January 2024 to roughly 70 percent by October 2025, according to internal financial data obtained by The Information. For comparison, Anthropic is expected to reach 53 percent by year's end.
OpenAI achieved these gains by cutting rental costs for computing power, optimizing its models, and launching a pricier subscription tier. Still, the company has a long road ahead before reaching profitability. CEO Sam Altman continues to plan major investments in additional computing power while pursuing further circular business arrangements.
OpenAI is reportedly working on a funding round of up to 100 billion dollars.
