Hand an AI a job that takes hours, and the plan goes missing partway through. Apodex 1.1 mini is a file anyone can download. It searches, runs code, and writes files. Its plan sits on a board outside the conversation.

Is it better to put one worker on a long job, or a team?
Apodex 1.1 technical report, arXiv 2608.23283 · Hugging Face model card, read 25 August 2026

Apodex 1.1 comes in two sizes. The big one is about eleven times larger, and it produced most of the headline numbers. That big model stays on Apodex's own servers. The small one is the file anyone can download and use, including in a business. Apodex also published the software that runs the model, and says the tests ran inside that software. So Apodex can run the same weights two ways. Is it better to put one worker on a long job, or a team?

The board outlives the conversation

the copy in charge writes the job down as numbered items
each item carries a state
openin progressresolvedcancelled
the items go out to copies working at the same time
each copy takes its scope from the board
the board sits outside the conversation
and the software keeps pasting it back in
“A normal final answer is accepted only after every active item is resolved or cancelled.”
Apodex 1.1 technical report, §3.3.2

A long job normally lives in the model's own conversation. That conversation gets rewritten and squeezed as it fills up, and the plan goes with it. Apodex writes the plan somewhere else. One copy of the model takes charge and breaks the job into numbered items, each one open, in progress, resolved or cancelled. The items go out to other copies working at the same time. Each copy takes its scope from the board. The software keeps pasting the board back into the copy in charge. And the board is a gate. The answer only goes out once every open item is closed.

Apodex 1.1 asks less of the checker than of the copy it checks

the whole problem, handed to a second model just as good
→ “a second, equally unconstrained chain of errors”
→ “another source of context pollution rather than a source of corrective signal”
one claim · the evidence behind it · the rule it has to meet
find an example that proves the claim wrong check the names, dates and numbers find a second source of a different kind check it against the format the job asked for
“The asymmetry is in the task, not necessarily in model size.”
Apodex 1.1 technical report, §3.2.3

How do you check someone's work without doing the work again? The obvious answer is to hand the whole problem to a second AI that is just as good. Apodex's team argue that this makes things worse. A second AI solving the whole thing invents a fresh set of mistakes. Now you have two stories instead of one answer. So Apodex narrows the job. The checker gets one claim, the evidence behind it, and the rule that claim has to meet. The checker's only task is to attack that claim. Hunt for an example that proves the claim wrong. Check the names, the dates and the numbers. What comes back names the claim, the evidence against it, and the repair.

Apodex’s own runs, the small model · report Table 5, 24 August 2026
third-party evaluations of these weights: zero · Artificial Analysis index, re-checked 25 August 2026

Every number here is Apodex's own. On the finance research questions, the same file scores forty points when one copy works the job alone, and fifty point two when a team of copies works it together. The weights never changed, and the gap is ten points. On science research and long multi-step tasks, the team gains six point seven points and three and a half.

the big model · report Table 8

These are the big model's numbers, on forty one search questions with a checkable answer. Working alone, about one question in five came back with nothing worth credit. Working as a team, about one question in ten came back empty. Wrong answers stayed rare both ways. Apodex published all forty one questions, and the programs that mark the answers, so anyone can run the test.

“Apodex 1.1 remains behind the frontier systems.”
The report gives the team’s answer, and gives no token or clock cost for it. One agent, same budget, is still untested.
97 science workflows, full credit only · nine of the eleven rows ran in the same common software · report Table 9

Apodex ran the big model in its own team system, and again in the common software nine of the eleven rows used. In its own team system the big model earned full credit on twelve point four percent of ninety-seven science workflows. In the common software, ten point three. The report says Apodex sits behind the leading systems, and those leaders earned full credit on twenty point six percent of the workflows. The report gives no time or token cost for a team run, so one agent on the same budget is still untested.

The plan sits on a board, and the answer waits until every item is closed. The checker gets one claim to attack. Ten points came from those two choices.
