Show HN: A Multi-agent system where LLMs challenge each other's answershttps://news.ycombinator.com/item?id=46435835Hey HN,I've been experimenting with forcing multiple LLMs to critique each other before producing a final answer.In practice, I kept working around single-model limitations by opening multiple tabs, pasting the same question into different models, comparing responses, and then manually challenging each model with the others' arguments. (Maybe some of you can relate.) It worked sometimes, but it was cumbersome, slow, and hard to do systematically and efficiently.Based on my own experiments, a few things seem to drive why different models arrive at different responses: they have different guardrails, different tendencies encoded in their weights, and different training data. And the biggest kicker of all: they still hallucinate. The question I wanted to test was whether making those differences explicit, rather than relying on one model to self-correct could reduce blind spots and improve the overall quality of the answer.So I built Consilium9.The problem: When a single LLM answers a conDec 30, 2025 5:41 PM

Show HN: Beauty Arena – An Elo-based experiment to measure aestheticshttps://beautyarena.vercel.appHi HN,I built Beauty Arena to solve a data problem I've always found annoying: absolute rating scales (1-10) are terrible for subjective data. They suffer from massive inflation and inconsistent user baselines (one person's 7 is another person's 5).I wanted to test if pairwise comparison (1v1) could produce a cleaner, strictly relative dataset.Instead of asking "How beautiful is this person?", the system asks a simple question: "Who do you choose?". It uses a ranking system inspired by competitive games (Elo/Glicko) under the hood. As users vote, a global ranking emerges based on win/loss ratios against others rather than accumulated points.I'm curious about the "wisdom of the crowd" limits here. Does a pairwise sort actually converge on a clear consensus, or does it cycle indefinitely due to intransitive preferences (A > B, B > C, but C > A)?I'd love feedback on the ranking methodology and the overall UI.Dec 30, 2025 12:56 AM

Show HN: Talent Scout – job matching and prep with an independent AI assessorhttps://news.ycombinator.com/item?id=46394163Hi HN — we’re opening Talent Scout to a wider beta and inviting the first 50 people to request access via our site.Talent Scout is built around the idea that resumes are an outdated medium for job search - it's easier to compress/summarize a detailed career history for a specific job than it is to try and decompress/extrapolate from a streamlined resume. Essentially, the job market today is a DDOS attack on HR departments, where spam applications prevent the candidates they actually want from being seen or reviewed. LLMs excel at summarization and translation tasks, so we sit as a platform between candidates and hiring managers to summarize your career history and translate that into the language of a specific hiring manager or recruiter.What you can do in the beta:- Interview prep with Athena (AI). Talk through your real work experiences the way you would with a trusted colleague over coffee or a beer.
