AI Model Comparisons
Which model wins which kind of argument, and which platform actually lets them argue. Comparisons based on running the debates rather than on spec sheets.
Why benchmarks are the wrong lens
A benchmark measures a model answering alone. That tells you how often it is right. It says nothing about how it is wrong, and for multi-model work that is the property that matters.
Three models with identical scores and identical failure modes are worth barely more than one. Three that fail differently are worth more than three times one, because each covers the others' blind spots. No leaderboard captures that, which is why the comparisons here are written from watching models argue rather than from spec sheets.
The pairing matters more than the pick
The strongest single finding across everything on this page: which models you put together matters more than which models you choose. Two from the same family share training data, tuning philosophy and blind spots — they disagree about phrasing and agree about substance. Two from different labs disagree about something.
A practical consequence is that the most expensive option is usually not the right one. Two current-generation mid-tier models from different providers reliably out-argue two flagships from the same provider, and cost less doing it. Tier also does not track release date: model pricing falls over time, so a newer model is sometimes cheaper than the one it replaces.

New to multi-model AI conversation? The homepage explains what it is and when it beats asking one model, and how it works covers the orchestration in detail. The other pillars are guides, comparisons and tools.
The premise behind all of it — that models critiquing each other produce better answers than one model alone — comes out of published research on multiagent debate.
