EchoArena: Local LLM Debate Arena
Make two LLMs debate. Third judges. 100% local, no cloud.
EchoArena: Local LLM Debate Arena launched on December 3, 2025.
What it does
Two local LLMs debate any topic (PRO vs CON) while a third model judges. 100% offline, no cloud APIs. Perfect for exploring arguments, testing LLM reasoning, and understanding different model perspectives without bias.

Run an Agent Council of LLMs that debate and synthesize answersMar 2026 · github.com · ▲8I built a local-first UI that adds two reasoning architectures on top of small models like Qwen, Llama and Mistral: a sequential Thinking Pipeline (Plan → Execute → Critique) and a parallel Agent Council where multiple expert models debate in parallel and a Judge synthesizes the best answer. No API keys, zero .env setup — just pip install multimind. Benchmark on GSM8K shows measurable accuracy gains vs. single-model inference.
Chat with multiple LLMs: o1-high-effort, Sonnet 3.5, GPT-4o, and more2025 · polychat.co · ▲62Hello HN! I was fed up switching between multiple UIs to ask GPT, Claude, etc… the same question and comparing the answers. So I built a way to ask multiple models the same question efficiently by having the LLM compare the responses and only show you new and valuable information from the 2nd model. This way you still get a fast response as normal from the 1st model, but also get any added value provided by the 2nd model. Initially I built my own UI to use this, but stumbled upon Open WebUI (formerly Ollama WebUI) which is fantastic, but is made more for local access to LLMs. So I talked to…

Community, All the HN belong to you. This is an archive of hacker news that fits in your browser. When I made HN Made of Primes I realized I could probably do this offline sqlite/wasm thing with the whole GBs of archive. The whole dataset. So I tried it, and this is it. Have Hacker News on your device. Go to this repo (https://github.com/DOSAYGO-STUDIO/HackerBook): you can download it. Big Query -> ETL -> npx serve docs - that's it. 20 years of HN arguments and beauty, can be yours forever. So they'll never die. Ever. It's the unkillable static archive of HN and it's…
