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 pipeline, ranging from RAG, Agents to classical NLP tasks like text classification and named entity recognition. It is easy to get high performance even with just basic manual promting.
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 our optimization demonstration on a text classification task:

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

Light, Modular, and Model-agnositc Task Pipeline

LLMs are like water; AdalFlow help developers 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.

Only two fundamental but powerful base classes: Component for the pipeline and DataClass for data interaction with LLMs. The result is a library with bare minimum 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.

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 our Generator. Whether you need to optimize task instructions or few-shot demonstrations, our unified framework offers an easy way to diagnose, visualize, debug, and train your pipeline.

This Trace Graph demonstrates how our auto-differentiation works.

Trainable Task Pipeline

Just define it as a Parameter and pass it to our 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.

Quick Install

AdalFlow: A Tribute to Ada Lovelace

AdalFlow is named in honor of Ada Lovelace, the pioneering female mathematician who first recognized that machines could do more than just calculations. As a female-led team, we aim to inspire more women to enter the AI field.
