IT WRITES THE THING
Large refactors, type discipline, builds that pass first time. When the answer has to run, this is the seat that makes it run.

SEVERAL OF THE
BEST MODELS.
ONE ANSWER.
One request reaches every seat in turn. Each takes the part it leads on and leaves the work better than it found it. What comes back is one answer, with the reasoning underneath it.

One answer
Merged from five seats
ONE LAUNCH SITE
Four of five signed off. The fifth disagreed, and that disagreement ships with the answer.
02/07How it works
A RELAY, NOT A VOTE.
Five models answering the same question in parallel and averaging the result produces the blandest of the five. So they do not work in parallel. Each seat receives the work so far and improves it in the one dimension it leads on — and may rewrite anything earlier if it can genuinely make it better.
The hand-off carries the reasoning, not just the conclusion. That is the mechanism by which several models beat one: each seat inherits the thinking of the seat before it.
Occasionally a seat will not put its name on the result. When that happens it is recorded and shown beneath the answer, rather than averaged away. Most runs have no disagreement, and that is the point — one that always disagrees means nothing.
03/07The seatsFIVE CAPABILITIES.
FIVE CAPABILITIES.
ONE LEAD EACH.
The seats are shown by capability rather than by model name. The roster changes as models are released, and a name we have not verified is a name we will not print.
IT FINDS THE SOURCE
Retrieval, citation, and then the source behind the source. It comes back with what the others would have asserted from memory.

IT HOLDS THE ARGUMENT
Long chains, contested premises, trade-offs with no clean answer. It is the seat that refuses the shortcut the other four would take.

IT KILLS THE SAFE OPTION
Naming, tone, direction. The part a committee averages into nothing, held by the one seat willing to be disagreed with.

Screenshots, whiteboards, scanned pages, the photograph of a napkin. The seat that can look at what you actually have.

WHAT YOU PASTE IN
STAYS YOURS.
Three things about your work, each of which the architecture actually enforces — not a policy we ask you to take on trust.
01
Your request goes to several model providers
Each one is named on the sub-processor list, with what it receives and which country it processes it in. We make no claim about whether they train on it — their terms differ per model and change without notice, so it is not a promise we could keep.
02
Every run is traceable
You see which model wrote which part, what it was given, and where it would not sign off. Nothing is merged silently.
03
Delete a run and it is gone
The row and everything attached to it are removed. There is no hidden copy marked deleted.

EVERY PLAN RUNS
THE SAME MODELS.
Plans differ on how many seats work on a run, how many runs you get, and whether UltraZeta depth is available. They do not differ on model quality — a Starter customer gets the same models as everyone else.
