Show HN: A multi-model interface where LLMs discuss & argue with each other

Hey HN, I am Robin from Rauno (link: https://rauno.ai). I built this tool because I’m tired of AI hallucinations.

I got sick of manually copy-pasting every prompt into 3 different windows just to verify the truth. I realized the only way to get real accuracy was to let the models debate & fact-check each other in real-time, in one screen. I couldn't find any platform online that does this and actually works smooth and user-friendly, so I ended up throwing this together just to make my own life easier.

I built an orchestration layer that runs the models in sequence and manages the state and context windows so they can actually debate. The backend routes the conversation to make sure they are skeptical towards each other's opinions, to make sure they catch each other's flaws in thinking. By talking to each other, the models immediately call out each other’s mistakes and when you push a little more, they definitely don't hold back. It currently supports recent models like Claude Sonnet 4.6, Gemini 3.1 Pro and ChatGPT 5.2.

Running this is pretty token-heavy, but the free tier is open so you can test if the approach works for your workflows. Would love to hear your feedback.

Love the idea.

Similar to https://news.ycombinator.com/item?id=47507666 …much to learn from each other, I think.

I am working on a similar hobby project, but for local models and human participation: https://github.com/ch4bes/roundtable

Edit: Asked “what year is it” which gets mixed result if using an LLM without tools.

Results were accurate: https://rauno.ai/c/7nEx8PAVMD

Compared to: https://opper.ai/ai-roundtable/questions/what-year-is-it-7a0...

Thanks! And thank god my tool passed the 'what year is it' test you tried haha.

I tried Opper now you sent it, and they're both similar AI roundtable tools indeed, but my main goal for Rauno was that the user actually sees what every model says, in real-time. To see every perspective of every AI model, so it actually becomes a lively discussion. But opper definitely has some great points too!

Would love to see yours when it's done.

		I like the idea of a real-time discussion. Going to try that as an option in my hobby project. HN is a great place to share projects like these. So much to learn from each other. Thanks for sharing yours!

A short conversation about coffee regions (free trial ran out quite quickly)

That's some high level expert coffee talk! And it's always fun if they try to outsmart eachother. Are they accurate in your opinion? I know literally nothing about obscure types of coffee :-)

I know very little about obscure coffee as well.

I do know that coffee comes from East Africa / Ethiopia, and that there are many varieties there due to this.

Heirloom varieties tend to be more “wild”. Farmers growing in regions outside of Ethiopia tend to select stable varieties to match the region.

I don’t know about the frost protection from deep canyons, but it makes sense.

I opened a bag of freshly roasted heirloom beans from Jimma, Ethiopia this morning, and they were indeed more tart and fruity than the Colombian variety I had earlier in the week. The discussion tracked with my experience, at least.

		Haha neat. Let me know if you have more obscure findings on Rauno. A free account gets you 10 more free prompts a day.
