  "account": "1. Mistral Large 4, a trillion-parameter model, has been made available to developers. Named \"Le Chonk,\" Mistral Large 4 is a multimodal mixture-of-experts model with 1 trillion total parameters, 50 billion active per token, and a 1 million token context window. The model is trained from scratch on European infrastructure and uses a modified MIT license that allows free use, modification, fine-tuning, and commercialization, with a condition for companies running Model-as-a-Service offerings to obtain a separate commercial agreement.\n\n2. DeepMind's WeatherNext Cyclones system has achieved a historic breakthrough in tropical cyclone forecasting by providing more than a full day of additional lead time, equivalent to a decade of meteorological progress. The system operates using just 28 by 28 kilometer data, 100 times coarser than traditional models, and still delivers accurate intensity predictions. Coarse grids are now shown to be as effective as high-resolution ones, but the scientific reasoning behind this remains an open question. The system's code, model weights, and operationalized WeatherNext 2 as well as the 2-mini variant are now publicly available.\n\n3. xAI has enabled watermarking by default across its Grok API. Starting November 7, text output from seven Grok model variants carries an invisible statistical watermark, which can be verified through a per-request x-watermark header. Opting out is intentionally difficult, reserved for team admins, and requires confirming a legal exception. The decision to make watermarking the default state for all outputs comes in the wake of the EU AI Act's Article 50(2) deadline set for December 2. This marks the first major frontier API to implement default-on watermarking, providing an industry-wide template for meeting the transparency deadline.",
  "summary": "Mistral put a trillion-parameter model into every developer's hands, DeepMind handed meteorologists a full extra day of hurricane warning time, and xAI quietly flipped on watermarking across its entire API. Here is the November 9 edition of AI Daily Digest, covering seven stories from the past few days with official sources anchored on every item. 1. Mistral releases the weights of Mistral Large…",
