Pocket Flow - LLM Framework in 100 Lines
[](https://the-pocket.github.io/PocketFlow/)
A [100-line](pocketflow/__init__.py) minimalist LLM framework for ([Multi-](https://the-pocket.github.io/PocketFlow/multi_agent.html))[Agents](https://the-pocket.github.io/PocketFlow/agent.html), [Workflow](https://the-pocket.github.io/PocketFlow/decomp.html), [RAG](https://the-pocket.github.io/PocketFlow/rag.html), etc.
- Install via ```pip install pocketflow```, or just copy the [source code](pocketflow/__init__.py) (only 100 lines).

## Why Pocket Flow?
Pocket Flow lets you **build LLM apps just by chatting with agents like Cursor AI**—no need for low-level coding.
Pocket Flow is *designed for LLM Agents*. If you’re using Cursor AI...
1. **🫠 With LangChain-like frameworks**: Cursor AI gets overwhelmed by complex abstractions and calls deprecated functions by mistake.
2. **😐 With No Framework**: Cursor AI writes functional but lacks modularity and maintainability.
3. **🥰 With Pocket Flow**: (1) Minimal and expressive—easy for Cursor AI. (2) Nodes and flows keep the codes **modular and maintainable**. (3) The shared store **separates data from compute logic**.
With just 100 lines, Pocket Flow ensures Cursor AI follows good coding practices without sacrificing flexibility.

To set up:
- **[Cursor Rules](https://docs.cursor.com/context/rules-for-ai)**: Copy [.cursorrules](assets/.cursorrules) into your project’s root.
- **ChatGPT & Claude**: Create a project ([ChatGPT](https://help.openai.com/en/articles/10169521-using-projects-in-chatgpt) and[Claude](https://www.anthropic.com/news/projects)) and upload the [docs](docs) folder to project knowledge.
## What Is Pocket Flow?
The [100 lines](pocketflow/__init__.py) capture what we believe to be the core abstraction of LLM projects:
- **Computation**: A *graph* that breaks down tasks into nodes, with *branching, looping, and nesting*.
- **Communication**: A *shared store* that all nodes can read and write to.
From there, it’s easy to implement popular design patterns like ([Multi-](https://the-pocket.github.io/PocketFlow/multi_agent.html))[Agents](https://the-pocket.github.io/PocketFlow/agent.html), [Workflow](https://the-pocket.github.io/PocketFlow/decomp.html), [RAG](https://the-pocket.github.io/PocketFlow/rag.html), etc.
