Researchers from Beijing Jiaotong University developed “O1-CODER” with the aim of replicating OpenAI’s o1 model with a focus on improving coding tasks. Even though OpenAI’s o1 has gained significant recognition for his reasoning abilities, he may not be the best option for tasks related to programming and coding.
The O1-CODER framework integrates reinforcement learning (RL) and Monte Carlo tree search (MCTS) techniques to enhance System 2 thinking, which refers to a more deliberate and analytical form of reasoning.
Researchers highlight a crucial lesson: data is all you need. Over the past decade, AI development has focused on improving model architectures, from traditional techniques like SVM and DNN to more recent advances like Transformers.
As models have developed, emphasis has been placed on leveraging data effectively. The o1 model and O1-CODER continue this trend by using RL to generate reasoning data, which can be used for System-2 tasks. This shift toward better use of data is particularly important for tasks requiring complex reasoning, like coding, for which traditional data sets are not sufficient.

The researchers further noted that future versions will offer updated experimental results. These updates will likely provide insight into the model’s capabilities and improvements as it evolves.
The model actually understands the code
The researcher behind O1-CODER explained how the model trains a test case generator (TCG) to standardize code testing. It leverages MCTS to generate code with reasoning.
This approach allows the model to systematically address coding challenges. The model begins by creating pseudocode, which serves as a template, and then progresses to full code generation.
This two-step process ensures that the model understands the problem before starting to write the actual code. It first thinks about the problem and then generates the solution.
By combining reinforcement learning (RL) with MCTS, O1-CODER not only writes code but also learns to reason through the coding process. This approach helps the model solve more complex tasks.
This combination allows the model to think deeply about how to structure coding solutions. Through iterative training, the model improves its performance, generating better, more efficient code over time.
They emphasized that future versions of O1-CODER will focus on real-world applications. They believe it is crucial to adapt the model to real-world coding challenges for broader use.
The researchers also said that O1-CODER follows a similar path to AlphaGo and its evolution towards generalization. Just as AlphaGo evolved into AlphaGoZero and AlphaFold, o1-type models should be applied to more complex and real-world tasks, such as embodied intelligence and physical environments.
The environment is important
The paper also emphasizes the need to update the state of the environment, to ensure that the model remains adaptable as it moves from research to real-world deployment.
In addition to improving code generation, the authors propose generating test cases directly from coding questions. This method does not rely solely on predefined datasets, which improves the flexibility of the model.
This approach can be used during the inference phase. It allows the model to reason online without the need for predefined code, making it more adaptable to various situations.
The paper suggests that O1-CODER could have a significant impact on AI’s approach to solving complex problems. It aims to go beyond completing tasks to engage in deeper reasoning and critical thinking.
OpenAI’s o1 has encountered challenges in coding tasks in the past, leading to the emergence of several alternatives.
Notably, Google’s Gemini 2 is expected to outperform o1 by incorporating advanced reinforcement learning techniques and “chain of thought” processes, aimed at improving reasoning and problem-solving abilities.
Additionally, DeepSeek, a Chinese AI research lab, introduced the DeepSeek-R1-Lite-Preview model, which is said to have matched or exceeded o1 in complex tasks such as math and coding.
In November, Alibaba also launched its Marco-o1 to compete with OpenAI o1. Even though it was recently released QwQ-32b The model presents itself as a direct competitor to o1.
