Show HN: SkeptAI – adversarial reasoning agent that challenges LLM outputs
I built this after Claude cited an API feature that doesn't exist in a work analysis that I almost forwarded to a client. CRIT (the custom framework that I built behind it) runs four structured adversarial passes on any LLM output and delivers a scored verdict. Cross-model critique (Claude output gets challenged by GPT-4o and vice versa) to prevent self-referential bias. Free playground, open source framework. Think of it as a "Digital Devil's Advocate". Check it out and let
Show HN: Interactive 3D and 2D Visualization of GPT-2
I’ve been building an interactive 3D + 2D visualization of GPT-2. It displays real activations and attention scores extracted from GPT-2 Small (124M) during a forward pass. The goal is to make it easier to learn how LLMs work by showing what is happening inside the model.<p>The 3D part is built with Three.js, and the 2D part is built with plain HTML/CSS/JS.<p>Would love to hear your thoughts or feedback!

Claude, GPT, and Gemini all attempt simultaneously. Experts flag errors with professional reasoning. Other credentialed professionals in the same domain verify them.AI benchmark performance has decoupled from real-world professional capability. Models score at or near ceiling on standard evaluations while still failing in ways that domain
Show HN: Yansu – agent that builds your bespoke app before you ask
Hi HNMost teams run on a dozen SaaS tools and use maybe 20% of each. The rest is someone else's workflow that you're paying for.We built Yansu to fix that. It learns how you work — your desktop, your Slack, your Teams — and proactively builds bespoke tools tailored to you. You don’t need to prompt. It sees a pattern, builds a solution, and surfaces it for you to use or toss.Like, I do the same things before every call: look through Linkedin, see any open threads on email, read the late
