Accompanying the release, the Qwen team published a blog post titled ‘QwQ-32B: Harnessing the Power of Reinforcement Learning,’ detailing the groundbreaking advancements.

The Power of Reinforcement Learning

The blog post emphasizes the immense potential of large-scale reinforcement learning (RL) to surpass traditional pre-training and post-training methods in enhancing model performance. Recent research, such as DeepSeek-R1’s integration of cold-start data and multi-stage training, showcases RL’s ability to significantly boost reasoning capabilities, enabling deeper thinking and complex problem-solving.

The Qwen team’s exploration focused on leveraging large-scale RL to elevate the intelligence of large language models, culminating in the creation of QwQ-32B. This 32 billion parameter model remarkably rivals the performance of the 67.1 billion parameter (with 37 billion activated) DeepSeek-R1. The team emphasized, ‘This achievement underscores the effectiveness of applying reinforcement learning to robust, pre-trained foundation models.’

QwQ-32B also incorporates agent-related capabilities, enabling it to critically evaluate its actions while using tools and adapt its reasoning process based on environmental feedback. ‘We hope our efforts demonstrate that combining powerful foundation models with large-scale reinforcement learning might be a viable path towards Artificial General Intelligence (AGI),’ the team stated.

Model Performance: Benchmarking QwQ-32B

QwQ-32B underwent rigorous evaluation across a range of benchmarks, encompassing mathematical reasoning, programming, and general capabilities. The results showcase QwQ-32B’s performance in comparison to other leading models, including DeepSeek-R1-Distilled-Qwen-32B, DeepSeek-R1-Distilled-Llama-70B, o1-mini, and the original DeepSeek-R1.

The findings are striking. QwQ-32B demonstrates exceptional performance, even slightly surpassing DeepSeek-R1-67B on the LiveBench, IFEval, and BFCL benchmarks. This highlights the efficiency and power of the reinforcement learning approach adopted by the Qwen team. The specific benchmark results demonstrate QwQ-32B’s strengths across various tasks:

• Mathematical Reasoning: QwQ-32B shows significant improvements in mathematical problem-solving, indicating the effectiveness of RL in enhancing logical deduction and numerical reasoning.
• Programming: The model excels in coding tasks, demonstrating its ability to understand and generate code that meets specific requirements, as validated by the code execution server feedback.
• General Capabilities: QwQ-32B maintains strong performance across a range of general benchmarks, showcasing its versatility and broad applicability. This indicates that the RL training has not compromised the model’s overall language understanding and generation abilities.

The comparison with other models, particularly DeepSeek-R1, is crucial. DeepSeek-R1, with its significantly larger parameter count, represents a state-of-the-art model. QwQ-32B’s ability to match or even exceed its performance in certain areas, despite being less than half its size, is a testament to the power of the Qwen team’s RL approach. This suggests that RL can be a more efficient way to achieve high performance compared to simply increasing model size.

Deep Dive into Reinforcement Learning Methodology

QwQ-32B’s development leveraged large-scale reinforcement learning built upon a cold-start foundation. The initial phase concentrated specifically on RL training for mathematical and programming tasks. Unlike traditional approaches relying on reward models, the Qwen team provided feedback for mathematical problems by verifying the correctness of generated answers. For coding tasks, feedback was derived from a code execution server, assessing whether the generated code successfully passed test cases.

This direct feedback mechanism is a key differentiator. Instead of relying on a separate reward model to estimate the quality of the output, the Qwen team used ground truth – the actual correctness of the answer or the success of the code – to guide the learning process. This provides a more accurate and reliable signal for the model to learn from.

As training progressed through multiple iterations, QwQ-32B exhibited consistent performance improvements in both domains. This iterative refinement process, guided by direct feedback on solution accuracy, proved highly effective. The iterative nature of the training is also important. The model continuously refines its performance based on the feedback it receives, leading to gradual but consistent improvements over time.

Following the initial RL phase focused on math and programming, a subsequent RL phase was introduced to enhance general capabilities. This stage utilized general reward models and rule-based validators for training. The results indicated that even a small number of steps in general RL could boost overall capabilities without significantly impacting performance on the previously trained mathematical and programming tasks. This demonstrates the adaptability and robustness of the model.

The use of general reward models and rule-based validators in the second phase allows the model to improve its performance on a broader range of tasks. Importantly, this enhancement of general capabilities does not come at the cost of the specialized skills (math and programming) acquired in the first phase. This indicates that the model is able to learn new skills without forgetting previously learned ones, a crucial aspect of continual learning.

The entire RL process can be summarized as follows:

1. Cold-Start Foundation: The model begins with a pre-trained foundation, providing a strong base level of language understanding and generation capabilities.
2. Specialized RL (Math & Programming): The model undergoes intensive RL training focused on mathematical and programming tasks, using direct feedback on solution accuracy.
3. Iterative Refinement: The model’s performance is continuously improved through multiple iterations of RL, with feedback guiding the learning process.
4. General RL: A subsequent RL phase enhances general capabilities using reward models and rule-based validators.
5. Balanced Performance: The model achieves strong performance across all tasks, demonstrating both specialized skills and general language abilities.
