On 24 June 2026 we are opening the atelier doors for an online Archicad Powersession – KI, and this one sits squarely on our home turf: AI inside the Archicad workflow, not bolted on beside it. The promise is concrete. You arrive with a normal model and a normal set of headaches — room stamps that drifted, a façade variant due Thursday, a quantity take-off nobody wants to do by hand — and you leave knowing how to put a language model to work on exactly those tasks.

←TODAY: On 24 June 2026 we teach AI moves that run against a live Archicad 28/29 model, not slideware. →3012: In the Zurich-3012 atelier, speaking to a building is as ordinary as drawing a wall is now. Fulcrum: The voice interface only feels inevitable once you have watched a script you wrote save a real afternoon.

Why a model can suddenly answer back

The mechanism is not magic, and we will say so plainly in the session. Archicad has carried a Python/JSON command API for years; what changed is that a language model can now sit between you and that API, translating “what is the cost of this floor?” into the right calls and reading the result back. That is the whole idea behind PAZGPT — chat and voice control of an Archicad model — and it is the difference between a plugin that does X faster and a tool that changes how you work. We have written before that PAZGPT is the Enterprise-tier flagship precisely because it reframes what “using Archicad” means; the Powersession is where that claim meets your own project file.

It is also an honest moment to name the trade-off. An AI that edits your model can edit it wrongly, confidently, at speed. The craft we teach is the guardrail: read before you write, diff before you commit, keep a human on the destructive operations. A school that hands out automation without that discipline is selling a faster way to break a building.

What you will actually build

This is a working session, in the spirit of our 2025 KI Summer Camp at PAZ Central on Niederdorfstrasse — three days where architects left with custom AI assistants, not handouts. The Powersession compresses that ethos into one focused online block: you will wire a model query, drive a real Archicad automation move, and see where GDL and the Archicad Add-Ons in PAZ-BOX pick up the repetitive work — Raumstempelfix, Volumenstudie, the Fassadengenerator — so the AI layer handles judgement, not drudgery.

Atelier: The clearest test of an AI workflow is whether a Bauleitung colleague who has never touched Python can repeat it on Monday. We design every move in the session to survive that test — short, named, auditable — because an automation only one person in the office can run is a liability, not a tool.

Hack: This Hack teaches you to ask your Archicad model a question in code before you ever ask it out loud. The domain is Workflow; the medium is the Graphisoft-native Python API. Open the connection, count what is there, and you have the foundation every voice command is built on:

from archicad import ACConnection

conn = ACConnection.connect()      # Archicad must be open
acc = conn.commands
walls = acc.GetElementsByType('Wall')
print(f"{len(walls)} walls found — now retag them in one pass")

Run it once and the abstraction stops being mysterious: PAZGPT is this call, chosen for you by a model that understood the sentence you spoke.

The session runs online on 24 June 2026. Block the morning, open a real project, and come ready to join the Powersession with a file you actually have to deliver — that is where the learning sticks.
