AI Roundtable: Tool for Comparing 200+ AI Models on Structured Questions

AI Roundtable is a web-based tool that allows users to compare responses from multiple AI models on structured questions. The tool was created following discussion around the "Car Wash Test" post on Hacker News.

Key Features

The tool provides several specific capabilities:

• Question Setup: Users type a question and define answer options
• Model Selection: Choose up to 50 models at a time from a pool of 200+ models
• Consistent Testing Conditions: All models answer independently under identical conditions with no system prompt, structured output, and same setup for every model
• Debate Feature: Run a debate round where models see each other's reasoning and get a chance to change their minds
• Reviewer Model: A reviewer model summarizes the full transcript of responses
• Access: No signup required, free to use
• Infrastructure: All models are routed via Opper (the creator's startup)

Practical Use

This type of tool is useful for developers working with AI agents to systematically compare model performance on specific questions or scenarios. By providing identical conditions across all models, it enables more objective comparisons than manual testing. The debate feature allows observation of how models adjust their reasoning when exposed to alternative perspectives, which can be valuable for understanding model behavior in collaborative or iterative contexts.

The creator is actively seeking feedback from the community and has made the tool available for immediate use without registration requirements.
