What it does
Coze Loop helps teams manage the whole life of an AI agent. It has a playground for writing and comparing prompts, the instructions given to AI models, with version history.
It can test prompts and agents automatically against sets of examples, checking things like accuracy. It also records every step an agent takes, so developers can see what happened and fix problems.
This is the open-source edition of a commercial product. It connects to AI models such as OpenAI and Volcengine Ark.
Who it's for
Developers and teams building AI agents who need to test and monitor them.
