Papers with Code – The #1 Free Resource for AI & Machine Learning Research
Papers with Code is an indispensable, free web platform for AI researchers, engineers, and students. It solves a critical bottleneck in machine learning by automatically linking cutting-edge research papers with their official code repositories, datasets, and benchmark results. This bridge between theory and practice accelerates innovation, enables reproducibility, and helps you implement state-of-the-art models faster than ever before.
What is Papers with Code?
Papers with Code is a massive, community-driven index that systematically connects machine learning papers published on arXiv with their associated code (typically from GitHub), datasets, and evaluation metrics. It transforms the traditional, fragmented research workflow into a streamlined discovery engine. Instead of searching multiple sources, researchers can find a paper, immediately see if code exists, check its performance on leaderboards, and download necessary datasets—all on a single, unified platform. It's the fastest way to go from reading about a novel architecture to running experiments with it.
Key Features of Papers with Code
Automated Paper-Code Linking
The platform's core technology automatically scans arXiv submissions and GitHub repositories to find matches, creating a living, up-to-date index. This ensures you discover the most recent implementations as soon as they're published, saving hours of manual searching.
State-of-the-Art Leaderboards
Compare model performance across hundreds of tasks (like ImageNet classification or GLUE benchmark) on centralized leaderboards. This feature is crucial for understanding the competitive landscape and identifying the best-performing architectures for your specific problem.
Integrated Datasets
Directly access and download the datasets used in papers. Each dataset page provides descriptions, download links, and papers that have utilized it, making data acquisition for replication studies or new projects seamless.
Powerful Search & Filtering
Filter papers by task (e.g., Object Detection, Text Generation), dataset, conference, year, or code framework (PyTorch, TensorFlow, JAX). This targeted search helps you quickly find the most relevant research for your work.
Trends & Methods Pages
Visualize the popularity of research areas over time and explore curated pages detailing specific ML methods (e.g., Transformers, GANs) with key papers and code. This is perfect for literature reviews and staying on top of emerging trends.
Who Should Use Papers with Code?
Papers with Code is essential for anyone actively engaged in the machine learning ecosystem. AI Researchers use it to track SOTA, find baselines, and ensure their work is reproducible. Machine Learning Engineers and Practitioners rely on it to find production-ready implementations to integrate into applications. Data Scientists utilize it to discover novel methods for solving complex data problems. Finally, Graduate Students and Academics find it invaluable for literature reviews, thesis research, and course projects, as it dramatically reduces the time from concept to implementation.
