Mini-R1: Reproducing DeepSeek R1 'Aha Moment' — An RL Tutorial
A Hugging Face blog post demonstrates how to reproduce DeepSeek R1's emergent 'aha moment' reasoning behavior using reinforcement learning on a countdown game task. The tutorial walks through training a smaller model with RL to exhibit chain-of-thought self-correction, similar to the behavior observed in DeepSeek R1. This serves as a practical open-source replication effort aimed at demystifying R1's training dynamics.

Open-R1: Update #1 — Open Reproduction of DeepSeek-R1
Hugging Face's Open-R1 project provides a first progress update on its open reproduction of DeepSeek-R1, a reasoning-focused language model. The update covers early training runs, dataset construction, and evaluation results aimed at replicating DeepSeek-R1's chain-of-thought reasoning capabilities. This effort is part of the broader open-weights community push to reproduce frontier reasoning models transparently.
Open-R1: a fully open reproduction of DeepSeek-R1
Hugging Face announced Open-R1, a community effort to fully reproduce DeepSeek-R1's training pipeline using open-source components. The project aims to replicate the data, training, and evaluation stages of DeepSeek-R1, making the entire process transparent and accessible. This follows significant interest in DeepSeek-R1's reinforcement-learning-based reasoning approach and addresses the lack of fully open reproduction of that methodology.
Open R1: Update #4
Hugging Face's Open R1 project releases its fourth progress update on the open reproduction of DeepSeek-R1. The update likely covers training progress, dataset releases, and evaluation results for the open-weights reasoning model effort. This project is a community-driven attempt to replicate and open-source the techniques behind DeepSeek-R1's chain-of-thought reasoning capabilities.
Open R1: Update #2
Hugging Face's Open R1 project releases its second progress update on the open-source replication of DeepSeek-R1's reasoning capabilities. The update likely covers training progress, dataset releases, and intermediate model checkpoints as the team works toward a fully open reproduction of the reasoning model pipeline. Open R1 is a community-driven effort to make the techniques behind frontier reasoning models accessible to researchers.
Hugging Face open reproduction of DeepSeek-R1
Hugging Face has published an open reproduction of DeepSeek-R1, the reasoning-focused language model, on GitHub. The project aims to replicate DeepSeek-R1's training methodology and capabilities in an open-weights setting. This contributes to the broader effort to make frontier reasoning model techniques accessible to the research community.
Open R1: Update #3
Hugging Face's Open R1 project releases its third update, continuing the open-source replication effort of DeepSeek-R1's reasoning model training pipeline. The update likely covers progress on data, training runs, and evaluation results for the community-driven reproduction. This is part of an ongoing effort to make frontier reasoning model capabilities accessible via open weights and open training code.
DeepSeek-R1-Lite-Preview Launched with o1-Level Reasoning Performance
DeepSeek has released DeepSeek-R1-Lite-Preview, a reasoning-focused model claiming o1-preview-level performance on AIME and MATH benchmarks. The model features a transparent, real-time chain-of-thought process and demonstrates inference scaling behavior where longer reasoning chains yield better results. DeepSeek has indicated that open-source model weights and a full API are forthcoming. The model is currently accessible via chat.deepseek.com.
DeepSeek-R1-0528 Released with Improved Benchmarks, Reduced Hallucinations, and Function Calling
DeepSeek has released DeepSeek-R1-0528, an updated version of its R1 reasoning model featuring improved benchmark performance, reduced hallucinations, enhanced front-end capabilities, and new support for JSON output and function calling. The API interface remains unchanged, and open-source weights are available on Hugging Face. This is an incremental update to the R1 series rather than a new flagship model.
