Kosong - Moonshot AI's New Open Source AI Agent Development Framework

What's Kosong?

Kosong is a new open source AI Agent development framework from Moonshot AI that provides developers with a lightweight, flexible, and highly scalable underlying support for building next-generation intelligent body applications. Through the asynchronous tool scheduling engine , can efficiently schedule multiple tools to execute in parallel , greatly improving the response efficiency of the agent and task completion rate . Kosong using plug-in design , support for pluggable chat provider (Chat Provider), developers can freely switch or mix the call of different models , such as Kimi, DeepSeek, Llama3 , etc., no need to modify the core business logic . Core business logic.Kosong is built on modern Python ecosystem, requires Python 3.13 and above, and recommends using the new generation package manager uv for installation.

Features of Kosong

• Asynchronous tool orchestration: Kosong's asynchronous tool scheduling engine enables efficient scheduling of multiple tools to execute in parallel, such as calling weather APIs, map services, and calendar systems at the same time. It enables developers to build complex task flows such as "Is it going to rain at 10am tomorrow? If so, help me change to an indoor cafe", thus dramatically improving agent response efficiency and task completion rate.
• plug-in design: The framework supports pluggable chat providers (Chat Provider), developers can freely switch or mix calls to different models, such as Kimi, DeepSeek, Llama3, etc., without modifying the core business logic. It avoids developers being bound by a single AI service provider and enhances the flexibility of technology selection.
• Out-of-the-box Python support: Kosong is built on the modern Python ecosystem, requires Python 3.13 and above, and is recommended to be installed using the new generation package manager uv. Officials provide complete sample code, from calling Kimi models, implementing streaming responses to customizing asynchronous tools (e.g. addition functions, database queries), the code is concise and clear. The built-in demo agent allows users to run it with a single click by setting environment variables and experience a complete AI agent workflow in 5 minutes.

Kosong's core strengths

• Efficient asynchronous processing: Kosong is able to schedule multiple tasks to execute in parallel at the same time through an asynchronous tool orchestration engine, which significantly improves task processing efficiency and responsiveness, and is suitable for handling complex multi-tasking scenarios.
• Flexible plug-in design: Supporting pluggable chat providers and tool modules, developers can freely switch or mix multiple AI models without modifying core business logic, enhancing development flexibility.
• Unified LLM abstraction layer: A unified large-scale language model (LLM) abstraction layer has been constructed to encapsulate different models and tools into standardized components, solving the problems of interface incompatibility and tool fragmentation and simplifying the development process.
• Modern Python ecosystem support: Built on Python 3.13 and above, it takes full advantage of the asynchronous programming features of modern Python, while supporting a new generation of package managers uv to ensure compatibility with the modern Python ecosystem.
• Getting Started and Developing Quickly: Provide complete sample code and built-in demo agent, developers can quickly start and run through a simple configuration of environment variables to reduce the development threshold and accelerate the development cycle.
• Highly scalable: Kosong's architecture is designed to allow developers to extend functionality as needed, supporting the integration of more tools and models to meet the needs of projects of varying size and complexity.
• Open Source and Community Support: As an open source project, Kosong provides complete code and documentation on GitHub, where developers can freely access, contribute, and obtain community support to promote technology exchange and innovation.
