DeepSeek has made waves in the AI community with the release of their R1 series of reasoning models, demonstrating that significant AI advancements can be achieved with relatively modest resources. The company, which built their V3 model with just USD $5.5M in compute costs, is now offering open-weights models that reportedly match or exceed the performance of leading commercial alternatives at a fraction of the cost.

Novel Approach to Reasoning
DeepSeek R1 introduces a groundbreaking approach by demonstrating that reasoning capabilities can be developed purely through reinforcement learning (RL), without requiring supervised fine-tuning (SFT). This achievement represents a significant departure from traditional methods, showing that models can naturally develop complex reasoning behaviors through RL alone. The model's distinctive feature is its visible thinking process, which exposes its reasoning chain in a way that has garnered both praise and criticism from the community.
Performance and Accessibility
The R1 series includes various distilled models ranging from 1.5B to 70B parameters, making it accessible to users with different computational resources. Community testing reveals that even the smaller distilled models show impressive capabilities on specific tasks, though with some limitations. The models are released under the MIT license, allowing for commercial use and modifications, including distillation for training other LLMs.
The ceo: In the face of disruptive technologies, moats created by closed source are temporary. Even OpenAI's closed source approach can't prevent others from catching up. So we anchor our value in our team — our colleagues grow through this process, accumulate know-how, and form an organization and culture capable of innovation. That's our moat.
Technical Challenges and Limitations
Users report mixed experiences with the models, particularly noting issues with function calling and occasional hallucinations. A recurring observation is the models' tendency for verbose thinking outputs, which some find excessive. The 64K input token limit and 8K output token limit are also cited as potential constraints compared to some commercial alternatives. However, the community has developed various workarounds, including chunking and RAG implementations.
Impact on AI Landscape
DeepSeek's approach represents a significant challenge to established players in the AI industry. By achieving comparable results with substantially lower compute costs and openly sharing their technology, they're demonstrating that effective AI development doesn't necessarily require massive computational resources. This could have far-reaching implications for the democratization of AI technology and the future development of reasoning models.
The release of DeepSeek R1 marks a notable milestone in open-source AI development, showing that sophisticated reasoning capabilities can be achieved through innovative approaches rather than just raw computational power. While the models have their limitations, their performance-to-cost ratio and open nature make them a significant contribution to the field.
