: We release the
Skywork-OR1
(Open Reasoner 1) series of models, including
Skywork-OR1-Math-7B
,
Skywork-OR1-32B-Preview
, and
Skywork-OR1-7B-Preview
. We open-source
We also release a
Notion Blog
to share detailed training recipes and extensive experimental results, analysis, and insights, dedicated to helping the community to better research, understand, and push the frontier of open reasoning models.
📖 Overview
The AIME24 scores versus training steps of Skywork-OR1-Math-7B in our multi-stage training pipeline.
The
Skywork-OR1
(Open Reasoner 1) model series consists of powerful math and code reasoning models trained using large-scale rule-based reinforcement learning with carefully designed datasets and training recipes. This series includes two general-purpose reasoning modelsl,
Skywork-OR1-7B-Preview
and
Skywork-OR1-32B-Preview
, along with a math-specialized model,
Skywork-OR1-Math-7B
.
Skywork-OR1-Math-7B
is specifically optimized for mathematical reasoning, scoring
69.8
on AIME24 and
52.3
on AIME25 — well ahead of all models of similar size.
Skywork-OR1-32B-Preview
delivers the 671B-parameter Deepseek-R1 performance on math tasks (AIME24 and AIME25) and coding tasks (LiveCodeBench).
Skywork-OR1-7B-Preview
outperforms all similarly sized models in both math and coding scenarios.
The final release version will be available in two weeks.
📊 Evaluation
We evaluate our models on AIME24, AIME25, and LiveCodeBench. Instead of using Pass@1, which is common in prior work, we introduce Avg@K as the primary metric. This metric robustly measures a model's average performance across K independent attempts, reducing the impact of randomness and enhancing the reliability of the results. We believe that Avg@K provides a better reflection of a model's stability and reasoning consistency.
We include the detailed results in the following table.

⚙️ Training Recipe
We offer a brief overview of our data and training pipeline below. For more details, please refer to our Notion Blog
here
.
Data
We select, clean, and curate
a dataset of 110K verifiable, challenging, and diverse math problems and 14K coding questions
from open-source datasets.
We perform
model-aware difficulty estimation
for each problem and model and conduct
rigorous quality assessment prior to training
to ensure training efficiency and effectiveness.
Training
We develop a customized version of GRPO that leverages both data-wise and training-wise improvements:
We perform both
offline and online difficulty-based filtering
and
rejection sampling
to improve training efficiency.
We incorporate a
multi-stage training pipeline
coupled with
adaptive entropy control
and other techniques to enhance exploration and stability.
