AI Roundtable

AI Roundtable is a free tool from Opper that puts the same question to many AI models at once and lets them debate and vote. Each model first answers independently, then reads the others' arguments and can rebut them or change its vote, and the session ends with a verdict of consensus, majority or a split decision. The point is to see where models such as Claude, GPT, Gemini and Grok agree and where they diverge, rather than trusting a single chatbot. It suits developers and teams choosing between models, researchers probing how models reason, refuse or show bias, and curious users testing tricky questions. Three formats are offered: a poll, where every model answers and votes once; a debate, which adds discussion rounds; and an open question with no fixed options, where the roundtable summarizes the positions taken. Users pick the lineup for every question from more than 200 models served through the Opper gateway, including DeepSeek, GLM and Kimi alongside the major labs. Asking is free and needs no account while an Opper sponsored credit pool has credits. When the pool runs dry, users sign up and continue with their own Opper credits. Opper's gateway pricing is pay as you go with no token markup and a platform fee: 3 percent on the Gateway tier, 5.5 percent on Control Plane, and custom terms for Enterprise. The roundtable grew out of the Car Wash Test, an Opper experiment by Felix Wunderlich that tested 53 models ten times each on the same simple reasoning question against a human control group.
