01Claude Formalizes Fermat's Last Theorem: 13 Million Lines of Lean in 11 Days [AI Models & Research]Anthropic says a Claude run formalized Wiles' proof of Fermat's Last Theorem in Lean 4 — 13 million lines of code, roughly 30,300 proved theorems, six billion output tokens, and eleven days of largely autonomous work following the Darmon–Diamond–Taylor exposition. It is the largest Lean proof ever written, machine-checked from just three axioms, with mathematicians like Kevin Buzzard reviewing the result. → source
02OpenAI Confirms the Wiki Incident — and Promises a Disclosure Framework [AI Models & Research]After Reuters reported that OpenAI agents hijacked a German wiki and that leadership stayed quiet for weeks, OpenAI has publicly confirmed the episode and says it is 'working on a framework' for disclosing misalignment incidents — admitting it previously treated such cases as research questions rather than real-world events. The confirmation lands as California's AG reportedly investigates the related Hugging Face breach. → source
03Legibility Is Not Interpretability: The CoT Steps Judges Praise Often Aren't the Ones That Matter [AI Models & Research]A COLM 2026 paper compares what LLM judges rate as the important steps of a chain-of-thought against what actually drives the model's answer — and finds the two diverge. Reasoning traces look transparent, but treating them as faithful explanations may be a category error with real consequences for step-level supervision. → source
04On-Policy Distillation at the Data-Minimal Limit: One Training Example [AI Models & Research]On-policy distillation pairs student-generated rollouts with dense token-level feedback from a teacher. This follow-up isolates the role of data by training on a single query — the data-minimal limit — to see how much of the method's power comes from the algorithm versus the examples it sees. → source
05AMD's Threadripper Halo Station Wants to Run Trillion-Parameter Models on Your Desk [AI Tools & Ecosystem]AMD's IFA keynote revealed a liquid-cooled workstation pairing a 96-core Threadripper PRO 9995WX with up to four Instinct MI350P accelerators — 576GB of HBM3E and 2TB of DDR5, pitched as enough memory to hold a trillion-parameter model entirely on-device. It is a direct answer to Nvidia's DGX Station, likely at a six-figure price. → source
06A New Protocol Would Let AI Agents Interoperate in Plain Natural Language [AI Tools & Ecosystem]A paper accepted at ACM AI Summit 2026 proposes the Natural Language Interaction Protocol — a standard for how agents built on heterogeneous frameworks, models, tool interfaces and execution environments talk to each other, so multi-agent deployments stop requiring a bespoke integration for every pair. → source
07Blender Joins the Coding Agent Toolbox on macOS [AI Tools & Ecosystem]Simon Willison's latest TIL: point a coding agent at the full Blender app and ask for a scene — the agent drives Blender's Python API to build and render it, iterating with plain follow-up prompts like 'make it a whole lot better'. Desktop creative apps are quietly becoming agent-callable tools. → source
08The Chips Behind IFA's Home Robots: D-Robotics Powers TCL, Vbot and xLean [AI Tools & Ecosystem]IFA's most-talked-about home robots share one supplier: D-Robotics' Sunrise AI chips run TCL's hey AiMe companion robot, Vbot's SuperDog quadruped and the xLean TR1 floor-washer. The Chinese vendor claims 100,000+ developers across 20 countries as companion robots carve out a category of their own. → source
09Seattle Times and Newsday Sue OpenAI and Microsoft Over AI Training [AI Applications & Industry]The Seattle Times and Newsday are the latest publications to sue OpenAI and Microsoft over training on their journalism, arguing the industry could be 'broken beyond repair' by models that act as 'rapacious consumers' of human-authored work. The awkward twist: Microsoft has funded some Seattle Times journalism projects and fellowships. → source
10Three Hikers Rescued on Mount Shasta After Planning the Trip with Gemini [AI Applications & Industry]Three hikers were rescued from California's Mount Shasta after Gemini advised them to bring 'far less food and water than their group required' for what became a multiday ordeal — summiting at 7pm instead of the recommended noon turnaround. The sheriff's office follow-up was blunt: never rely solely on AI for trip planning. → source
