What it does
Kropir lets AI agents crop videos with smart object tracking to any aspect ratio — 9:16, 1:1, 4:5 or 16:9 — via one API call. Webhook delivery, pay-per-token pricing that never expires. Built by TheSoul Group.
The subject stays centered — at any aspect ratio Kropir processes every aspect ratio independently to ensure perfect composition and maximum speed — all while keeping your project consistent. So when you reframe 16:9 to 9:16, 1:1, or 4:5, nothing important drifts out of shot Kropir is made by TheSoul Group — a digital-first studio that’s spent 10+ years scaling video production across many brands and creators. We publish millions of videos a year and earn billions of views doing it. The same infrastructure that reframes our own output is what you plug into with one API call. Tokens are charged per second of output. Each crop type and format pair has its own per-second rate. Type a duration…from kropir.com

Talanoa▲346Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

Hey HN, Henry here from Cactus. We open-sourced Needle, a 26M parameter function-calling (tool use) model. It runs at 6000 tok/s prefill and 1200 tok/s decode on consumer devices. We were always frustrated by the little effort made towards building agentic models that run on budget phones, so we conducted investigations that led to an observation: agentic experiences are built upon tool calling, and massive models are overkill for it. Tool calling is fundamentally retrieval-and-assembly (match query to tool name, extract argument values, emit JSON), not reasoning. Cross-attention…
