While reinforcement learning powered much of DeepSeek's training, the process also leveraged carefully curated cold start datasets. These small collections of labeled examples spanning multiple domains gave the model an initial foundation to build upon.
Some key benefits of using cold start data in DeepSeek's training:
Importantly, the cold start datasets used to train DeepSeek were much smaller than the huge corpora typically used for language models. This allowed the researchers to maintain efficiency while still benefiting from some supervised learning.
By combining targeted cold start fine-tuning with large-scale reinforcement learning, DeepSeek achieved impressive performance in its ultimate training regimen. This hybrid approach was crucial to creating a model that was both capable and computationally practical.
As DeepSeek's training advanced, the technique of rejection sampling proved invaluable for refining the quality of the model's training data. The process worked like this:
By repeatedly filtering the model's own outputs and recycling only the best samples, DeepSeek created a virtuous cycle of self-improvement. The more it trained, the better its generations became, leading to higher quality synthetic data to learn from.

This approach was a key factor in how DeepSeek was trained to achieve strong performance while maintaining computational efficiency. Rejection sampling amplified the benefits of the model's reinforcement learning and helped steer it toward more coherent, relevant, and useful outputs.
DeepSeek's training methodology incorporated several cutting-edge techniques that drove significant gains in efficiency and performance. By rethinking traditional approaches, the team unlocked new possibilities for open-source AI development.
One key innovation was the use of the Group Relative Policy Optimization (GRPO) reinforcement learning framework. Unlike standard RL setups that rely on a separate "critic" model to evaluate the main model's outputs, GRPO scores the outputs directly against predefined rules. This critic-free approach streamlines the training pipeline and reduces the potential for biased feedback from imperfect labeled data.
Alongside GRPO, DeepSeek invested heavily in strategic reward engineering. The team meticulously designed scoring functions to incentivize desirable model behaviors and penalize inconsistencies or mistakes. Rather than simply optimizing for matching known answers, these rewards pushed the model to develop important attributes like logical coherence, relevant formatting, and fluent, human-like responses.
Another notable innovation was the use of knowledge distillation to compress the model's learnings into smaller, more efficient versions. By training lightweight models to mimic the outputs and reasoning of the full-scale version, DeepSeek significantly reduced memory and compute requirements without major performance sacrifices. Distilled models as small as 1.5B parameters exhibited reasoning capabilities on par with far larger architectures.
Together, these training innovations formed the foundation of how DeepSeek was trained to achieve state-of-the-art results with exceptional efficiency. The open-source release of models trained using these techniques has the potential to accelerate the entire AI field.
One of the key innovations in DeepSeek's training process was the use of the Group Relative Policy Optimization (GRPO) reinforcement learning framework. This novel approach eliminated the need for a separate "critic" model, which is commonly used in traditional RL setups to evaluate the main model's decisions and guide its improvement.
Instead of relying on a critic, GRPO directly scores the model's outputs over multiple rounds using a set of predefined, rule-based metrics. These metrics assess important attributes like coherence, completeness, and adherence to the desired format.
By removing the critic model from the training loop, DeepSeek streamlined the learning process and avoided potential limitations and biases that can arise from using imperfect labeled data to train the critic.
This critic-free approach, made possible by the GRPO framework, played a significant role in DeepSeek's training methodology. It allowed the model to learn more efficiently and achieve strong performance across a wide range of language tasks.

In the critic-free reinforcement learning approach used to train DeepSeek, the design of the reward scoring rules took on heightened importance. The DeepSeek team invested significant effort into reward engineering - carefully constructing functions that would incentivize the model to exhibit desirable behaviors and characteristics.
Rather than simply rewarding the model for matching known answers or maximizing raw accuracy, these scoring rules were meticulously crafted to capture a range of important attributes:
By penalizing outputs that contained errors or inconsistencies while positively reinforcing responses that demonstrated strong reasoning, contextual awareness, and language understanding, DeepSeek's reward engineering amplified the effectiveness of the reinforcement learning process in training the model.
Knowledge distillation emerged as a powerful technique in DeepSeek's training process for creating compact yet capable models. The approach involves training smaller "student" models to replicate the outputs and decision-making of a larger "teacher" model.
DeepSeek researchers found that by carefully tuning the distillation process, they could create models with as few as 1.5 billion parameters that exhibited reasoning abilities comparable to their much larger counterparts with hundreds of billions of parameters.
Some key benefits of the distilled models include:
Importantly, the distilled models achieved these efficiency gains while still maintaining a high degree of performance on complex language tasks. This success demonstrates the potential for creating compact, cost-effective models that retain the capabilities of their larger, more resource-intensive counterparts.

DeepSeek's training process, which spanned from 2023 to 2025, resulted in a series of increasingly sophisticated models that shook up the AI industry. The journey began with domain-specific models like DeepSeek Coder, aimed at programming tasks with its 236B parameters and expansive context window.
But the real game-changer arrived in December 2024 with DeepSeek-V3. Boasting 671B parameters and a mixture-of-experts architecture, V3 efficiently tackled a wide range of language challenges, posting impressive results on general benchmarks.
The culmination of DeepSeek's training innovations came in the form of DeepSeek-R1. By incorporating an advanced reasoning module, R1 could go head-to-head with top models from OpenAI and Anthropic on complex tasks like:
Most remarkably, R1 achieved this performance while maintaining a significantly lower cost profile compared to its rivals.

As DeepSeek continues to refine its training process and deploy cutting-edge techniques, the AI community eagerly awaits the next leap forward in this rapidly-evolving field. The DeepSeek model timeline stands as a testament to the power of thoughtful, efficient training methodologies in pushing the boundaries of what's possible with AI.
DeepSeek's training process started with a focus on specialized models for specific domains, and DeepSeek Coder was the first result of this approach. Aimed squarely at programming and software development tasks, Coder boasted an impressive 236B parameters and a vast 128,000 token context window.
This expansive context allowed DeepSeek Coder to process and understand large, complex codebases. It could handle challenging programming tasks like:
While DeepSeek Coder was narrower in scope compared to the broad language models that would come later, it established a strong foundation of targeted performance. By training deeply on a specialized corpus of programming data, Coder achieved state-of-the-art results on coding benchmarks.
This early success validated DeepSeek's training approach, which leveraged reinforcement learning, supervised fine-tuning, and intelligent rejection sampling to create highly capable models. The lessons learned from DeepSeek Coder would inform the development of future models as the researchers set their sights on ever-broader language challenges.
December 2024 marked a significant milestone in DeepSeek's training process with the release of the DeepSeek-V3 model. Boasting an impressive 671B parameters and a vast 128,000 token context window, V3 represented a major expansion of DeepSeek's capabilities beyond the specialized models that came before.
This increased scale allowed V3 to take on a much wider range of general language tasks, moving beyond the narrow focus of models like DeepSeek Coder. V3's training process leveraged the key techniques that had proven successful:
However, V3 also introduced a notable architectural innovation in the form of a mixture-of-experts (MoE) approach. In this design, the model intelligently routes different parts of each input to specialized sub-models that are experts in particular domains or tasks.
By combining the outputs of these expert models, V3 could efficiently handle diverse workloads and improve overall compute efficiency. The MoE architecture allowed DeepSeek to get the most out of V3's expanded scale and showcase strong performance across a range of general language benchmarks.
The leap from specialized Coder models to the large-scale, general-purpose V3 marked a key inflection point in DeepSeek's training journey. It set the stage for further innovations to come, like the reasoning-focused DeepSeek-R1 model that would follow.
DeepSeek's training process reached new heights with the release of the DeepSeek-R1 model, their most sophisticated offering to date. Building upon the strong foundation established by the V3 model, R1 incorporates a powerful new reasoning module that allows it to directly challenge the best models from industry leaders like OpenAI and Anthropic.
The key innovation in R1 is its multi-step "chain of thought" process for handling complex queries. When faced with a difficult question or task, R1 breaks it down into a series of smaller, more manageable logical operations. By tackling the problem step-by-step, R1 is able to perform advanced reasoning and arrive at accurate solutions.
This reasoning capability has enabled R1 to match the performance of top models like OpenAI's o1 on challenging benchmarks in areas such as:
Impressively, R1 has achieved these results while maintaining a significantly lower cost and computational footprint compared to its rivals. Through the use of efficient architectures and training techniques honed over the course of DeepSeek's journey - from reinforcement learning to mixture-of-experts models - R1 delivers state-of-the-art performance without the immense resource requirements of other leading models.
The release of DeepSeek-R1 marks a major milestone in the evolution of DeepSeek's training process and a new high watermark for open-source AI. As DeepSeek continues to refine and expand upon the innovations that led to R1, it will be exciting to see how they further push the boundaries of what's possible in accessible, cutting-edge language models.
