🤖 Anthropic launches Claude Duet work agent
LINK
|
- Anthropic launched Claude Duet, a proactive agent that connects to your apps and reaches out before you ask, suggesting items that need attention and completing tasks in the cloud without local access to your computer.
- Built on Opus 5.5, Duet sends a morning brief, rechecks connected apps every few hours, and runs in its own virtual machine with a browser, handling everything from admin chores to building web apps in one ongoing thread.
- It requests approval before sending messages, making payments, or deleting files, and never sees passwords, but Duet is a US-only research preview behind a waitlist for Pro and Max subscribers, with background checks counting against existing plan limits.

🌍 Nvidia expands Cosmos world-model tools
LINK
|
- Nvidia expanded its Cosmos world-model platform at GTC Berlin with Cosmos 3, new Data Factory blueprints, and Framework training tools for developers building physical AI systems that simulate the real world.
- Cosmos Data Factory ships five cloud-native blueprints, covering autonomous-vehicle data, defect imaging, and video augmentation, available through GitHub, Azure, Nebius, and CoreWeave, while Cosmos Framework lets developers fine-tune open models like GR00T, QWEN, and Pi0.5.
- Updated Cosmos 3 NIM microservices deliver up to 2x faster inference with no quality loss, and the Metropolis VSS 3.3 blueprint monitors 40% more video streams per GPU, though those inference gains apply only in validated configurations.

🐘 AI finds critical PHP flaws
LINK
|
- PHP shipped emergency updates yesterday fixing two critical memory-safety bugs that let unauthenticated attackers run code on nearly any server, after AI-assisted audits surfaced the flaws and a proof-of-concept exploit leaked online.
- Both bugs, rated 9.2 on CVSS v4, were first found in August by security firm Calif using OpenAI's GPT-5.6 Sol, then independently by Google's Wiz team with Wiz Atlas, Gemini 4 Argon and GPT-5.6 Sol.
- Patched releases span PHP 8.5.12 back to 8.2.35, with backported fixes for the unsupported 7.4, 8.0 and 8.1 branches given reach to PHP 5.4, though PHP warns no configuration change substitutes for updating.

💻 Recursive's AI built a coding model
LINK
|
- Recursive released Flint, a free coding model built largely by its own automated research system, the Eureka Machine, which a small team used to develop the laptop-ready model from scratch in under four months.
- Flint is a mixture-of-experts model activating 2.5B of 40B parameters, hitting ~131 tokens/sec on an M4 Pro MacBook Pro, roughly twice what Gemma 4 and Nemotron 3.5 Lightning managed, and beating other sub-50B models on SWE-Bench Verified.
- The model is free on Hugging Face under Apache 2.0 for offline, private coding without cloud fees, though Recursive admits Flint needs more hand-holding than big paid assistants and works best when large tasks are split into smaller steps.

🧬 Hugging Face AI chats with DNA
LINK
|
- Hugging Face on Thursday released Carbon-X, an open-source model that converses in natural language about DNA sequences and can run locally on a laptop, built with researchers at China's Zhongguancun Academy and Italy's University of Naples Federico II.
- The team expanded an existing language model's vocabulary to read DNA in six-letter groups, then trained on 300 billion tokens mixing genomic sequences from mammals, plants, and fungi with English text, deliberately excluding viruses to limit dangerous uses.
- At 14 billion parameters the model runs on local hardware so sensitive patient genomes never leave the user's machine, though it ingests only ~50,000 base pairs at a time and the developers haven't validated its prediction accuracy with wet lab experiments.
