Vibrant Labs

Vibrant Labs is an applied research lab that develops unsupervised environment design (UED) to autonomously generate reinforcement learning data for AI agents. Instead of relying on human annotators, the lab's systems let environments adapt to the agent, creating tasks at the frontier of its ability. This approach, building on PAIRED and regret-based UED, keeps agents in a state of continuous learning without saturating benchmarks. The lab focuses on two primary modalities: Tool-Use Agents (calling APIs and chaining tools in domains like ITSM, healthcare, finance, and customer support) and Computer Use Agents (navigating real UIs end-to-end for e-commerce, web research, and SaaS workflows). Flagship research includes Tau2-Infinity, a tool-use miner that harvests tasks within a target model's pass@k window, and Ecom Bench, a benchmark for verifiable shopping tasks on the live web. Vibrant Labs is built by the team behind Ragas, the open-source evaluation framework used by 80% of the Fortune 100. The lab is backed by Exploding Gradients Inc. and targets teams building long-horizon AI agents that need scalable, open-ended training data and self-evolving benchmarks. Unlike traditional RL data pipelines that require armies of human annotators or static environments that are quickly outgrown, Vibrant Labs provides autonomous data harvesting that adapts to the agent's growing capabilities. However, the tools are research-stage, with no public pricing or plug-and-play datasets, making them best suited for advanced research teams.
