Coze Loop – An AI Agent Development and Debugging Platform by ByteDance’s Coze

What is Coze Loop？

Coze Loop is an open-source platform launched by ByteDance’s Coze team, focused on the development and operations management of AI Agents. It provides developers with full-lifecycle management capabilities—including development, debugging, evaluation, and monitoring. Key features include prompt engineering, agent performance evaluation, performance monitoring and optimization, transparent decision monitoring, and multi-model comparison.

Coze Loop supports writing, optimizing, and versioning prompts, and offers AI-assisted enhancement tools to significantly improve development efficiency. Through a systematic evaluation framework, Coze Loop can automatically assess agent outputs across multiple dimensions to ensure accuracy and compliance. It also offers performance monitoring, anomaly alerts, and visualized decision traceability to help developers quickly identify issues and optimize model performance.

Coze Loop – Key Features

• Prompt Engineering: Enables writing, debugging, optimization, and version control for prompts, with AI-assisted tools to enhance development efficiency.

• Agent Performance Evaluation: Provides a systematic evaluation system to automatically assess prompts and AI agent outputs across dimensions like accuracy, clarity, and compliance.
