# 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*.
|
||
|
||
- **Lightweight**: Just the core graph abstraction in 100 lines. ZERO dependencies, and vendor lock-in.
|
||
- **Expressive**: Everything you love from larger frameworks—([Multi-](./design_pattern/multi_agent.html))[Agents](./design_pattern/agent.html), [Workflow](./design_pattern/workflow.html), [RAG](./design_pattern/rag.html), and more.
|
||
- **Agentic-Coding**: Intuitive enough for AI agents to help humans build complex LLM applications.

## Core Abstraction
|
||
|
||
We model the LLM workflow as a **Graph + Shared Store**:
|
||
|
||
- [Node](./core_abstraction/node.md) handles simple (LLM) tasks.
|
||
- [Flow](./core_abstraction/flow.md) connects nodes through **Actions** (labeled edges).
|
||
- [Shared Store](./core_abstraction/communication.md) enables communication between nodes within flows.
|
||
- [Batch](./core_abstraction/batch.md) nodes/flows allow for data-intensive tasks.
|
||
- [Async](./core_abstraction/async.md) nodes/flows allow waiting for asynchronous tasks.
|
||
- [(Advanced) Parallel](./core_abstraction/parallel.md) nodes/flows handle I/O-bound tasks.

||
## Design Pattern
|
||
|
||
From there, it’s easy to implement popular design patterns:
|
||
|
||
- [Agent](./design_pattern/agent.md) autonomously makes decisions.
|
||
- [Workflow](./design_pattern/workflow.md) chains multiple tasks into pipelines.
|
||
- [RAG](./design_pattern/rag.md) integrates data retrieval with generation.
|
||
- [Map Reduce](./design_pattern/mapreduce.md) splits data tasks into Map and Reduce steps.
|
||
- [Structured Output](./design_pattern/structure.md) formats outputs consistently.
|
||
- [(Advanced) Multi-Agents](./design_pattern/multi_agent.md) coordinate multiple agents.

## Utility Function
|
||
|
||
We **DON'T** provide built-in utility functions. Instead, please implement your own. I believe it is a **bad practice** to provide vendor-specific implementations in a general framework:
|
||
|
||
- **Vendor APIs change frequently**. Hardcoding them makes maintenance a nightmare.
|
||
- You may need **flexibility** to switch vendors, use fine-tuned models, or deploy local LLMs.
|
||
- You may need **optimizations** like prompt caching, request batching, or response streaming.
|
||
|
||
However, we provide example implementations for commonly used utility functions.
|
||
|
||
- [LLM Wrapper](./utility_function/llm.md)
|
||
- [Viz and Debug](./utility_function/viz.md)
|
||
- [Web Search](./utility_function/websearch.md)
|
||
- [Chunking](./utility_function/chunking.md)
|
||
- [Embedding](./utility_function/embedding.md)
|
||
- [Vector Databases](./utility_function/vector.md)
|
||
- [Text-to-Speech](./utility_function/text_to_speech.md)
