About Humanloop
Humanloop was an enterprise-grade AI evaluation platform that served as the first development platform for Large Language Model (LLM) applications. It provided best-in-class prompt management and LLM observability capabilities, enabling teams to build, test, and manage AI applications powered by LLMs. The platform was designed for enterprises and development teams looking to rapidly and safely adopt AI technologies. Humanloop shaped industry standards for how to manage and evaluate AI systems, but as of the time of the research, the company has joined Anthropic and is sunsetting the platform as the team transitions to work on new initiatives within Anthropic.
