Wikipedia is seeing fewer visitors: The Wikimedia Foundation says page views have dropped by about eight percent compared to last year. The foundation points to generative AI tools and social networks that display Wikipedia content without sending users to the site. Bots that increasingly resemble real users are also putting more strain on Wikipedia's infrastructure.

Wikipedia remains a core source for training AI models, the foundation notes, but direct visits to the site are falling. If this trend continues, the project could face long-term risks. To respond, Wikimedia is working on new formats for younger audiences, better mobile editing, and clearer guidelines for how others can use Wikipedia content.

25 years since its creation, Wikipedia’s human knowledge is more valuable to the world than ever before.

Italy's main publishers' group, FIEG (Federazione Italiana Editori Giornali), has filed a complaint with Italy's communications regulator, Agcom, targeting Google's AI Overviews. FIEG argues that these AI summaries appear directly in Google Search results, pushing journalistic content further down the page. The group says this setup violates key rules in the EU Digital Services Act (DSA), limiting the visibility of editorial content and causing revenue losses for publishers.

The European Publishers Association (ENPA) is backing similar complaints elsewhere in Europe. Publishers are pushing for EU-wide action against Google.

Spending on ChatGPT has leveled off in Europe, according to a new report from Deutsche Bank. The number of paying users hasn't grown since May 2025, even though the service reports 800 million weekly users worldwide. Free alternatives like Google AI Mode and Perplexity may be slowing down the growth of paid subscriptions. OpenAI is already exploring ways to monetize free users, possibly through advertising or commission-based sales links.

Similarweb data shows that ChatGPT's largest European markets are the United Kingdom (4.2 percent), France, and Germany (3.2 percent each). ChatGPT has now overtaken Disney Plus in Europe and brings in nearly half as much revenue as Spotify. If the pace holds, ChatGPT could surpass Spotify in 2027 and Netflix in 2028.

Hugging Face has launched HuggingChat Omni, an AI router that selects the best open source model for each user prompt from more than 100 available models. The system automatically chooses the fastest, cheapest, or most suitable model for each task, using an approach similar to the new GPT-5 router. Supported models include gpt-oss, qwen, deepseek, kimi, and smolLM.

Hugging Face co-founder Clément Delangue says HuggingChat Omni is just the beginning. The platform already offers access to more than two million open models, spanning not only text, but also images, audio, video, biology, chemistry, time series, and more.

The routing system is built on Arch-Router-1.5B from Katanemo, a lightweight 1.5 billion-parameter model that classifies queries by topic and action. Arch-Router claims it outperforms other models at matching human preferences and is fully open source. Details are available in the research paper on arXiv.
