TL;DR
A new open-source project has released a complete reproduction of DeepSeek-R1, allowing researchers to replicate its training pipeline and datasets. This effort aims to foster transparency and further development in AI reasoning models.
Open Reproduction of DeepSeek-R1 has been publicly released, providing the AI research community with open-source scripts, datasets, and instructions to replicate the model’s training pipeline and evaluation results.
The project, hosted on a GitHub repository, includes scripts for training, data generation, and evaluation, aimed at enabling full reproduction of DeepSeek-R1’s reasoning and coding performance. You can learn more about in-database durable execution techniques that are relevant to large-scale model training. The release follows a multi-stage plan, with the first step—creating a distilled reasoning dataset—already completed as of May 26, 2025.
The repository contains tools for training models with supervised fine-tuning (SFT) and group relative policy optimization (GRPO), along with datasets such as Mixture-of-Thoughts, CodeForces-CoTs, and Math traces. These datasets are distilled from DeepSeek-R1 and are designed to facilitate further research and model development.
Developers emphasize that the project is a work in progress, with ongoing plans to replicate the full reinforcement learning pipeline used to create DeepSeek-R1, including curating large-scale datasets for reasoning, math, and code tasks. The release also includes detailed instructions for setup, installation, and training on high-performance hardware, such as multiple H100 GPUs.
Implications for AI Transparency and Reproducibility
This open reproduction significantly advances transparency in large language model research by providing detailed, accessible resources for replicating DeepSeek-R1’s training pipeline and evaluation results. It enables researchers worldwide to verify, critique, and build upon the original model, fostering collaborative progress in AI reasoning and coding capabilities. Additionally, it lowers barriers for academic and independent researchers to experiment with high-quality datasets and training scripts, potentially accelerating innovation in the field.

Background and Progress of the Open R1 Project
DeepSeek-R1 is a state-of-the-art reasoning and coding language model developed by DeepSeek, which has been influential due to its high performance on benchmarks like math and programming tasks. Prior to this release, access was limited to proprietary training pipelines and datasets, hindering external validation and further research.
The Open R1 project aims to democratize access by providing open-source scripts, datasets, and instructions aligned with the original model’s training process. The project is structured into three main phases: reproducing the distilled reasoning datasets, replicating the reinforcement learning pipeline, and demonstrating multi-stage training from base models to RL-tuned variants. The first phase was completed in May 2025, with datasets like Mixture-of-Thoughts and CodeForces-CoTs already released.
While the initial datasets and training scripts are available, the full RL pipeline, which involves large-scale dataset curation and policy optimization, remains under development. The project team emphasizes transparency and collaborative development as core principles.
“Our goal is to enable the community to fully reproduce and build upon DeepSeek-R1, fostering transparency and collaborative progress.”

Remaining Challenges in Full Pipeline Reproduction
While datasets and training scripts are available, the complete reinforcement learning pipeline—particularly the large-scale dataset curation for math, reasoning, and code—remains under development. It is not yet clear when the full pipeline will be operational or how closely the open reproduction will match the original DeepSeek-R1 performance in all tasks.
Upcoming Developments for Complete Reproduction
The project team plans to release the remaining components of the RL pipeline, including large-scale datasets and policy optimization scripts, over the coming months. They also intend to validate the reproduction by benchmarking the open models against original results and encouraging community contributions for further improvements.
