Show HN: JevBench, a reproducible benchmark for typed decision models

Hi HN! I built JevBench because Jev kicks ass, and the world deserves to know how the serious open source and fake lookalike projects really perform in comparison. Jev-class models return bounded choices and probabilities instead of text, and are disruptively faster and cheaper than LLMs, while being similarly intelligent on the text input they operate on…

Show HN: Relay – a self-hosted LLM gateway with smart routing and request pacing

Hi, I’m Pavel. I’ve been building Relay, a self-hostable AI gateway. The main thing I wanted to solve was smart routing without turning the gateway itself into a bottleneck. Relay can classify an incoming request, decide what kind of model capabilities the request needs, then route it across your configured providers while also accounting for limits and a…

Show HN: Lightdrift / Image search for AI agents through API and MCP

Greetings HN, I'm Jackson, the founder of Lightdrift. It's an image search API and MCP that lets agents retrieve real images, along with natural language descriptions, metadata, provenance, and license conditions. I built this because I kept having the same problem and it was pissing me off. About a year ago, I was vibe coding on edibles. I decided to bui…

Show HN: Cross-platform governed memory for a fleet of agents

I found myself using the handoff skill too much — between sessions in different roles, and between different platforms (Codex and Claude for me). So, like programmers do, I wrote a solution for it: a shared memory for a fleet of agents, where each agent group has its own memory scope. After some time using it, I saw the memory become a pile of junk, so I…

Show HN: WebMCP Registry of Websites That Agents Can Use

We were going to keep this internal to Tomo, but we decided to ship this publicly in case for other agent builders! Introducing the WebMCP Registry: an open index of websites that give AI agents real tools, like "search flights" or "add to cart", so they can use the site directly instead of clicking through it. We loaded the top 100,000 sites in real brow…
