Pocket Flow: A [100-line](pocketflow/__init__.py) minimalist LLM framework
|
||
|
||
- **Expressive**: Support ([Multi-](https://the-pocket.github.io/PocketFlow/design_pattern/multi_agent.html))[Agents](https://the-pocket.github.io/PocketFlow/design_pattern/agent.html), [Workflow](https://the-pocket.github.io/PocketFlow/design_pattern/workflow.html), [RAG](https://the-pocket.github.io/PocketFlow/design_pattern/rag.html), etc.—everything you’d expect from larger frameworks.
|
||
|
||
- **Lightweight**: Only the *core graph abstraction* in 100 lines. No dependencies or vendor lock-ins.
|
||
|
||
- **Principled**: Designed for clear *modularity* and *separation of concerns*.
|
||
|
||
- To install, ```pip install pocketflow```or just copy the [source code](pocketflow/__init__.py) (only 100 lines).
|
||
|
||

## Why Pocket Flow?
|
||
|
||
For a new development paradigmn: **Build LLM Apps by Chatting with LLM agents, Not Coding**!
|
||
|
||
- 🧑 Human **describe LLM App requirements** in a design doc.
|
||
- 🤖 The agent (like Cursor AI) **implements App** your code automatically.

- **For quick questions**: Use the [GPT assistant](https://chatgpt.com/g/g-677464af36588191b9eba4901946557b-pocket-flow-assistant) (note: it uses older models not ideal for coding).
|
||
- **For one-time LLM task**: Create a [ChatGPT](https://help.openai.com/en/articles/10169521-using-projects-in-chatgpt) or [Claude](https://www.anthropic.com/news/projects) project; upload the [docs](docs) to project knowledge.
|
||
- **For LLM App development**: Use [Cursor AI](https://www.cursor.com/).
|
||
- If you want to start a new project, check out the [project template](https://github.com/The-Pocket/PocketFlow-Template-Python).
|
||
- If you already have a project, copy [.cursorrules](.cursorrules) to your project root as [Cursor Rules](https://docs.cursor.com/context/rules-for-ai).

|
||
|
||
Pocket Flow is <i>purpose-built for LLM Agents</i>:
|
||
1. **🫠 LangChain-like frameworks** overwhelm Cursor AI with *complex* abstractions, *deprecated* functions and *irritating* dependency issues.
|
||
2. 😐 **Without a framework**, code is *ad hoc*—suitable only for immediate tasks, *not modular or maintainable*.
|
||
3. **🥰 With Pocket Flow**: (1) Minimal and expressive—easy for Cursor AI to pick up. (2) *Nodes and Flows* keep everything *modular*. (3) A *Shared Store* decouples your data structure from compute logic.
|
||
|
||
In short, the **100 lines** ensures LLM Agents follows *solid coding practices* without sacrificing *flexibility*.

||
## How does Pocket Flow work?
|
||
|
||
The [100 lines](pocketflow/__init__.py) capture what we believe to be the core abstraction of LLM frameworks:
|
||
- **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/design_pattern/multi_agent.html))[Agents](https://the-pocket.github.io/PocketFlow/design_pattern/agent.html), [Workflow](https://the-pocket.github.io/PocketFlow/design_pattern/workflow.html), [RAG](https://the-pocket.github.io/PocketFlow/design_pattern/rag.html), etc.
