For AI researchers, product teams, and software engineers who want to learn the AI way.

Quick Start

Install AdalFlow with pip:

pip install adalflow

Please refer to the full installation guide for more details.

• Try the Building Quickstart in Colab to see how AdalFlow can build the task pipeline, including Chatbot, RAG, agent, and structured output.
• Try the Optimization Quickstart to see how AdalFlow can optimize the task pipeline.

Why AdalFlow

1. Embracing a design pattern similar to PyTorch, AdalFlow is powerful, light, modular, and robust. AdalFlow provides Model-agnostic building blocks to build LLM task pipelines, ranging from RAG, Agents to classical NLP tasks like text classification and named entity recognition. It is easy to get high performance only using manual prompting.
2. AdalFlow provides a unified auto-differentiative framework for both zero-shot prompt optimization and few-shot optimization. It advances existing auto-optimization research, including Text-Grad and DsPy. Through our research, Text-Grad 2.0 and Learn-to-Reason Few-shot In Context Learning, AdalFlow Trainer achieves the highest accuracy while being the most token-efficient.

Here is an optimization demonstration on a text classification task:

Among all libraries, AdalFlow achieved the highest accuracy with manual prompting (starting at 82%) and the highest accuracy after optimization.

Light, Modular, and Model-Agnostic Task Pipeline

LLMs are like water; AdalFlow help you quickly shape them into any applications, from GenAI applications such as chatbots, translation, summarization, code generation, RAG, and autonomous agents to classical NLP tasks like text classification and named entity recognition.

AdalFlow has two fundamental, but powerful, base classes: Component for the pipeline and DataClass for data interaction with LLMs. The result is a library with minimal abstraction, providing developers with maximum customizability.

You have full control over the prompt template, the model you use, and the output parsing for your task pipeline.

Many providers and models accessible via the same interface:

Unified Framework for Auto-Optimization

AdalFlow provides token-efficient and high-performing prompt optimization within a unified framework. To optimize your pipeline, simply define a Parameter and pass it to AdalFlow's Generator. Whether you need to optimize task instructions or run some few-shot demonstrations, AdalFlow's unified framework offers an easy way to diagnose, visualize, debug, and train your pipeline.

This Dynamic Computation Graph demonstrates how our auto-differentiation and the dynamic computation graph work.

No need to manually defined nodes and edges, AdalFlow will automatically trace the computation graph for you.

Trainable Task Pipeline

Just define it as a Parameter and pass it to AdalFlow's Generator.

AdalComponent & Trainer

AdalComponent acts as the 'interpreter' between task pipeline and the trainer, defining training and validation steps, optimizers, evaluators, loss functions, backward engine for textual gradients or tracing the demonstrations, the teacher generator.

AdalFlow: A Tribute to Ada Lovelace

AdalFlow is named in honor of Ada Lovelace, the pioneering female mathematician who first recognized that machines could go beyond mere calculations. As a team led by a female founder, we aim to inspire more women to pursue careers in AI.
