Show HN: Avoid LLM Sycophantry – Two Models Debate Any Claim

BotBicker is a site to get two sides on an issue by randomly assigning two LLMs to debate a topic. I built it as a way to explore ideas without getting stuck in an echo chamber, but I"m also using it now to avoid LLMs telling me what they think I want to hear.

It's free, and no login is required, debates start streaming immediately and take a few minutes (opening, rebuttals, 4 rounds on QA, and closings).

You can inject questions into the debate for each side, and at the end, it reveals which model was assigned to each side, and you get proposed follow-up debates to dig deeper into a topic.

It's using thinking models (o3,gemini-2.5-pro,grok-4-0709), I've also tried enabling web search tools. Pros are that the evidence is more detailed and they link to sources, cons are that the debate takes longer.

Curious to get any feedback, especially any other models you'd like to see or tools enabled.

Example debates (phase as a claim, not a question): -California’s state grid regulations are the most effective. -Charlie Chaplin is better than Buster Keaton. -Facial recognition technology should be banned from use in public spaces
