Show HN: Τ³-Bench is out – can agents handle complex docs and live calls?
τ-Bench is an open benchmark for evaluating AI agents on grounded, multi-turn customer service tasks with verifiable outcomes. It's been great to see the community adopt it since launch — this is now the third iteration. With τ³-Bench, we're extending it to two new settings: knowledge-intensive retrieval and full-duplex voice.τ-Knowledge: agents must navigate ~700 interconnected policy documents to complete multi-step tasks. Best frontier model (GPT-5.2, high reasoning) hits ~25%. The
Show HN: Robust LLM extractor for websites in TypeScript
We've been building data pipelines that scrape websites and extract structured data for a while now. If you've done this, you know the drill: you write CSS selectors, the site changes its layout, everything breaks at 2am, and you spend your morning rewriting parsers.LLMs seemed like the obvious fix — just throw the HTML at GPT and ask for JSON. Except in practice, it's more painful than that:- Raw HTML is full of nav bars, footers, and tracking junk that eats your token budget. A
Show HN: //Beforeyouship is a pre-build tool to estimate the LLM cost
For one of my projects, I needed to choose an LLM but got lost in numbers and tokenization. So I searched for a solution which could help me do the math, but only found tools that helped with cost management and optimization at the production stage. I did some research and found that this is an existing problem, especially if you are a vibe-coder or solo developer starting an AI-powered app from scratch.So I built an MVP to test with you guys — if any of you relate to the problem, please tell me
Show HN: Reading Tree, a weighted outline for articles instead of a summary
I built this for close reading, especially philosophy chapters, long essays, and dense nonfiction. AI summaries are useful in many cases, but sometimes the source is good enough that I want to read it properly, not just get the gist. Those are exactly the cases where a summary can leave out the parts I would care about most.Reading Tree keeps the original words in place. Every node links to the passage it covers, and every paragraph links back to the node that explains its role. Nodes are weight
Show HN: The Economics of Builder Saturation in Digital Markets
I formalised something most of us already feel but rarely say out loud: making things easier to build doesn't make things easier to succeed with.Personal version: I've vibe-coded maybe 15 projects since the beginning of this year. Two are still alive. At work, our teams built hundreds of custom GPTs and dashboards. Handful survived. The failure mode was never "couldn't build it" - it was "nobody had the bandwidth to care."So I wrote a paper about it. It combine
Show HN: Hollow – serverless web perception for AI agents
I wanted any AI Agent to access the web and perform tasks without costing me anything, which would normally require a browser running somewhere, but I didn’t want to run a headless browser or keep my laptop open. So I built an interface for agents that exists purely as a serverless function. The agent gets two primitives: ‘perceive’ and ‘act’.You POST a URL, get back a structured map, act on an element by ID. That's the whole interface. And it costs almost nothing, at approximately $0.00003

Show HN: Illustrative – AI pipeline that turns books into graphic novels
I like the idea of taking one thing and turning it into another—very much inspired by NotebookLM and wondered what it might take to generate full graphic novels, with consistent characters, narrative flow, story arc, etc.Developed a 7-pass scripting enrichment system (beat analysis, adaptation filtering, character deep dives) before generating any images.Dual backend: Google Gemini for scripting (2M context window) and either Gemini or OpenAI for image generation with 3-tier model fallback (comp
Show HN: Datetime-bench: which datetime formats LLMs get right (and wrong)
tl;dr* If you need an LLM to parse OR emit a timestamp, use: RFC 3339 ( e.g. 2024-03-26 10:30:00-05:00 ) * python date format also works well* Do NOT use unix epoch or javascript date formats.* Smaller models and non-reasoning models still make a LOT of mistakes in time parsing / formatting.---There are lots of temporal reasoning benchmarks (like TimeBench, TRAM, etc.) but they test whether models understand time concepts. Nothing on which datetime output format models get right most ofte
Show HN: Convene – Marketplace and management software for event organizers
We're software developers and farmers market/pop-up event organizers. In the past year we've run close to 200 events in NJ on Convene.markets - a booking engine, event management platform, and vendor marketplace for organizers to discover and connect with local makers, food purveyors, & farmers. We've spent the past few months opening up our platform for other organizers to now run their events and we'd love to connect with anyone running a farmers market, street fes
