# Pocket Flow

A [100-line](https://github.com/the-pocket/PocketFlow/blob/main/pocketflow/__init__.py) minimalist LLM framework for *Agents, Task Decomposition, RAG, etc*.

We model the LLM workflow as a **Graph + Shared Store**:
- **Nodes** handle simple (LLM) tasks.
- Nodes connect through **Actions** (labeled edges) for *Agents*.  
- **Flows** orchestrate a directed graph of Nodes for *Task Decomposition*.
- Nodes within Flows communicate through a **Shared Store**.
- A Flow can be used as a Node (for **Nesting**).
- **Batch** Nodes/Flows for data-intensive tasks.
- **Async** Nodes/Flows allow waits for asynchronous tasks.
