What it does

Chemin builds enterprise AI training data, model evaluation, and reinforcement learning workflows for robotics, agentic AI and autonomous vehicles. We help organizations collect, annotate, evaluate, and improve production AI systems through scalable data operations and human feedback.

Chemin builds enterprise AI training data, evaluation, and reinforcement learning workflows for robotics, agentic AI and autonomous vehicles.

Chemin builds the data pipelines and reinforcement learning workflows that power autonomous vehicles, robotics, and the production agents shipping next — supported by domain experts across 18 markets. We'll start by identifying your project's challenges, aligning on goals, and mapping out what is needed to deliver results. We'll collect and meticulously curate the data necessary for your models to perform at their best. We match you with the ideal AI model and guide it through a rigorous training process with human expertise. Our team of specialists analyzes the results and validates your model's performance through a pilot program. Your model is now up and running, but we'll still keep…from chemin.com

  Terminal-Bench-RL: Training long-horizon terminal agents with RL2025 · github.com · ▲125

  After training calculator agent via RL, I really wanted to go bigger! So I built RL infrastructure for training long-horizon terminal/coding agents that scales from 2x A100s to 32x H100s (~$1M worth of compute!) Without any training, my 32B agent hit #19 on Terminal-Bench leaderboard, beating Stanford's Terminus-Qwen3-235B-A22! With training... well, too expensive, but I bet the results would be good! *What I did*: - Created a Claude Code-inspired agent (system msg + tools) - Built Docker-isolated GRPO training where each rollout gets its own container - Developed a multi-agent…

  Built a multi-agent research system with OpenAI Agents SDK where specialized AI agents collaborate autonomously: Master Orchestrator → Data Analyst → Statistician → Report Writer Each agent has specific expertise. The orchestrator delegates tasks. All agents can execute code securely to solve problems. Example workflow: "Analyze e-commerce data" - Data Analyst: writes Python to load/clean data, spots trends - Statistician: performs significance tests, calculates growth rates - Report Writer: synthesizes findings into executive summary This demonstrates OpenAI Agents SDK's handoff system…

  Clipto MCP▲655

  Hey HN, We recently built Clipto. It’s a tool that lets you search over terabytes of video, audio, and images on your computer, without relying on the cloud. Motivation: we probably all had this similar experience, we know a moment exists in a video or audio, but finding it takes hours scrubbing the timeline. You can send all the media to process in the cloud, but it’s slow, expensive and raises privacy concerns. So we decided to build our own on-device media search engine. How it works (high level): 1. We ingest video, audio, image; normalize formats via ffmpeg; run content analysis to…

  Simple algorithm and color space to generate diverse skin tones▲627

  Hello HN! I found that picking out plausible but diverse skin tones for my digital art and game development projects was kind of difficult, and I got curious about if there was a way to define a color space that made it easy. I've built a color picker and procedural generation algorithm based on the space as well as a bunch of other fun js features and demos throughout the page that use the equations. If you find it interesting, I have lots of explanations of how I built it and what properties the space has. The methodology might be a bit shaky, but hopefully the result is as helpful for…
