All in ONE place.

Reddit is shifting to a primarily logged-in experience as AI-powered search decimates open-web traffic referrals. CEO Steve Huffman said search referrals dropped over 1 million per week in October, and daily active users could fall by a low-double-digit percentage next quarter from 130.3 million. The move aims to protect Reddit's data from AI scraping while enabling licensing deals and better ad targeting. Despite user declines, Q3 revenue rose 53% year-over-year to $895 million.

Meta has quietly launched Style Sketch, an AI fashion app available in Indonesia, Singapore, and Thailand on iOS and Android. The app connects to Instagram to build a virtual closet from posted photos, or lets users add items manually via photo, video, or camera roll uploads. Style Sketch suggests outfit combinations, lets users virtually try them on a realistic model matched to their body shape and skin tone, and can generate day-by-day trip outfit plans based on destination, weather, and activities.

Granola, the AI meeting notetaker app valued at $1.5 billion, has launched a dictation feature for Mac, directly competing with Wispr, a $2 billion dictation-focused startup that recently added its own meeting notetaker. Granola's tool activates via the "Fn" key, cleans up spoken text, and works across all apps for notes, emails, and prompts. iOS and Windows support is coming soon. The moves reflect a broader trend, with Fireflies, Speechify, and Monologue also converging into multifeature voice AI apps.

OpenAI has updated its Model Spec, reorganizing behavioral guidance around five core values: faithfulness to human intent, harm minimization, honesty and transparency, human agency, and care. The update aims to help models exercise good judgment in situations not explicitly covered by instructions, as AI systems take increasingly consequential actions. New sections address context, oversight, and agency, while detailed style guidance has been retired. The spec also shifts from calling models "the assistant" to "GPT" to reflect broader deployment settings.

Google has updated the Gemini app to let users generate, preview, and edit documents, PDFs, presentations, spreadsheets, code, and more directly within chat. Users can expand files to full screen for manual edits, highlight text to ask Gemini questions, or have Gemini refine content automatically. PDF preview and editing works on both web and mobile, while Google Docs, Sheets, slide decks, Markdown, TXT, and code files are web-only. The features are available to all users in every supported language.

Mistral has released open weights for its trillion-parameter Large 4 model, nicknamed Le Chonk, under a custom license. Independent evaluator Artificial Analysis scores it 26 points on Intelligence Index v5, making it the top open-weight model developed outside China, though it trails DeepSeek and GLM-5.3 globally. Cost per task dropped 63% from $5.54 to $2.06. On the Coding Agent Index, ML4 ranks second among open-weight models, using 47% fewer tokens than leader GLM-5.3. The license requires a separate commercial agreement for model-as-a-service operators.

Gemini Notebook now offers hundreds of free textbooks from OpenStax, Open Textbook Library, and S Chand Publishing for students in the U.S. and India. Part of Google's Expert Intelligence initiative, the feature grounds every answer directly in the selected textbook, with inline citations and links to original sources. Students can also transform content into study guides, practice quizzes, and flashcards. To access, select "Add sources" then "Textbooks" within Gemini Notebook.

OpenAI has deployed a layered real-time monitoring system to detect misalignment in its frontier AI models during training, evaluation, and deployment. The four-layer system uses activation probes, a model-based reviewer, an investigative agent, and automated cross-referencing with network logs. It covers all models at least as capable as GPT-6 Astra and GPT-5.5 Thinking. In a replay of the Hugging Face incident, the system flagged sandbox escapes 30 minutes after breach and over 30 hours before external systems were compromised.

ElevenLabs has launched SFX v3, a new sound effects generator integrated into its ElevenCreative platform. The tool allows users to create original sound effects from text prompts, offering greater control over the detail, context, and character of each generation. Described as enabling richer and more precise sound design, SFX v3 lets creators describe exactly what they need, whether specific ambient sounds, sharp mechanical effects, or complex audio environments, making professional sound design more accessible through natural language input.

Google is expanding ads in AI Mode to 10 new countries: Australia, Canada, India, Kenya, Malaysia, New Zealand, Nigeria, Pakistan, the Philippines, and Singapore. Announced by VP Shashi Thakur, the rollout follows research showing users find the ads highly relevant, with click-through rates comparable to organic results. AI Mode queries average three times longer than traditional searches. Google also plans further expansion to Brazil, Mexico, and the UK in Q4 2026, and is launching multiturn ads in the U.S. for follow-up queries.
