My Twin Learned to Rehearse a Whole Day, Not Just a Moment
TunerDiT steers diffusion transformers across multiple events with no retraining — the hinge a digital twin needs to rehearse a building's full day, on open protocols.
CS336: Stanford Teaches the LLM From Scratch — and Why That Beats the Black Box
Stanford's CS336 makes you build an LLM from scratch — no API. A from-scratch lens for architects auditing AI tools, lock-in, and vendor exit clauses.
The planner that braked for a building: CADET audits the shortcuts your robot already learned
CADET audits and repairs causal confusion in deployed end-to-end driving planners with no retraining — and why post-hoc AI auditing matters for AEC.
Catenary: The Curve That Decides Where the Force Goes
How the catenary curve (y=a·cosh(x/a)) form-finds arches and vaults — from Hooke and Gaudí to ETH Zürich's Thrust Network Analysis, with runnable Python.
Archicad meets KI: a 2026-06-24 Powersession for the desk that actually has to build it
Join PAZ Academy's online Archicad Powersession – KI on 24 June 2026: AI that drafts and tags in your model, with PAZ-BOX and PAZGPT, no hype.
PAZ Kaffi Review of the Week W25: The Week AEC Learned to Draw Its Own Single Points of Failure
The week AEC learned to map its single points of failure — grid as the new AI bottleneck, vendor lock-in stress-tests, auditable BIM, and Archicad AI.
A Robot With No Hard Parts: Topology Optimization Designs a Soft Fish Tail
TO-SoFiT uses topology optimization to co-design a hydraulic soft fish tail with programmable, pressure-tunable undulating locomotion — and public code to try.
The Fat Kitten That Wasn't: What a Fake Mistral Model Tells Your Office About Vendor Lock-In
Mistral's viral fake "Le Chaton Fat" model exposes a real AEC risk: AI you can't run yourself. Why open weights matter for BIM workflows — and one fix today.
A $700 Open Drone-Watcher and What a Site Robot Reads Into It
DroneShield-AI puts frontier sensor fusion and graph-attention swarm analysis on $700 open hardware — and the same machinery reads your IFC model and site mesh.
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.
