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.

Papers with Code Pricing and Free Tier

Papers with Code is completely free to use. There is no premium tier, subscription fee, or paywall. The entire platform—including access to all papers, code repositories, datasets, and leaderboards—is offered as a free public resource. This commitment to open access is foundational to its mission of accelerating machine learning research globally.
