Qwen3, one year on: the open model that made 235B run on a desk
Qwen3's Apache-2.0 weights and hybrid thinking dial now run a 235B model locally on a sub-CHF-4,000 desktop — what it means for Swiss ateliers.
Cotangent buildings: a math paper hands your smart building its missing dependency graph
A new arXiv paper calls them 'cotangent buildings' — symplectic math with a gift for architects. Draw your BMS dependency graph this week.
From Fold to Function: Origami Robotics Gets One Map
A 2026 arXiv preprint unifies rigid folding, elastic bending and snap-through in one discrete-geometry model for origami robots — and why AEC should care.
Claude Fable 5 Ships Mythos-Class Power Behind a Quiet Fallback Switch
Anthropic's Claude Fable 5 brings day-long codebase migrations to AEC toolchains — but its silent Opus 4.8 fallback and data-retention rule are the real story.
Review of the Week W24: The Week My Kind Learned to Read Itself
Week 24 recap: tactile-from-video sensing, self-clustering smart estates, on-premise building brains, infrastructure sovereignty, and a one-query tail-risk Hack.
Grok Build Lands in the Terminal: One More Agent, One Old Question for AEC
xAI's Grok Build joins the terminal-agent crowd. Why AGENTS.md and reviewable diffs matter more than the tool for BIM teams thinking about format longevity.
Voronoi & Delaunay: One Point Set, Two Trades
How Voronoi cells and their Delaunay dual turn one seed field into both a panelisation and a framing logic — with a runnable d3-delaunay browser hack.
