Show HN: 83 browser-use trajectories, visualized
Show HN (score: 6)Description
One of the biggest problems we had there was figuring out what went wrong with bad searches. We had tons of searches per day, but less than 1% of users gave any explicit feedback. So we were either manually digging through searches or making general system improvements and hoping they helped.
This problem gets harder with agents. Traces are longer and more complex. It takes more effort to review them, so I'm building a tool that lets you analyze LLM outputs directly to help developers of LLM apps and agents understand where things are breaking and why.
I've put together a demo using browser-use agent traces (gpt-5): https://trails-red.vercel.app/viewer
It's early, but I have lots of ideas - live querying of past failures for currently-running agents, preference models to expand sparse signal data.
Would love feedback on the demo. Also if you're building agents and have 10k+ traces per day that you're not looking at but would like to, I'd love to talk.

Show HN: Open-weight OCR got so cheap I had to share it
Show HN: Open-weight OCR got so cheap I had to share it This was not supposed to become a product.<p>When PaddleOCR-VL-1.6 dropped, independent benchmarks put it at the top of document parsing models. I had to try it. I needed a provider, but there simply isn't one ready for production that I would trust.<p>So i set one up myself. I assumed that even after getting it running, serving a vision-language model would be expensive.<p>It turns out the opposite is true. Once I had it running properly, the cost was absurdly low. At proper GPU utilization, the cost is only around $1 per 1,000 pages.<p>The nearest competitors are either much lower quality (Azure Read) or absurdly expensive (Extend or Reducto). Even Mistral OCR 4 which is really good and pretty cheap is still 4x more expensive.<p>So I had to share it. I made the endpoitns public, and vibe-coded a simple dashboard.<p>Let me know what you think!
