Two people, two machines

This run has two links, one per side. Each of them opens a page that shows that side and nothing of the other: their own words, their own limits, their own agent's brief.

Keep one. Send the other one to whoever is playing the other side. Neither of you writes the other's requirements, and neither of you sees them. When both have confirmed what they wrote, the negotiation starts on its own and you both watch it.

One spouse

What do they need, and what will they not agree to?

The other spouse

Each button opens its side in a new tab, and this page stays where it is. The link is what says which side you are — not a cookie — so two tabs on one machine really are two separate sides. To keep them further apart, open a private browser window yourself and paste the other link into it: a web page is not allowed to open one for you.

Which agents negotiate

Both sides are represented by the same tier. Choose before either side confirms.

Standard The everyday negotiator. Fast, and cheap enough to run all day. $2 in / $10 out per million tokens — up to $0.50 a run Pro A stronger model. Reads a tighter brief more carefully and holds its ground longer. $5 in / $25 out per million tokens — up to $1.20 a run Premium The most capable model there is. Costs several times a Standard run, and shows it in a hard negotiation. $10 in / $50 out per million tokens — up to $2.50 a run

Both links are on this page, so whoever opened it can read both sides if they want to. That is a property of handing out two links on one screen, not a claim we are making — the separation this demonstrates is between the two agents, and that one holds however the links were shared. Keep this page to yourself and open only your own side.
