‍

10 Common Misconceptions About DeepSeek

‍

Like any other new tech, rumors and speculations are bubbling up around DeepSeek. In this section, Dirox will clear up the 10 most common misconceptions about this new AI model!

‍

‍

1. DeepSeek built their model for just $5.6 million.

‍

The $5.6 million figure only accounts for the final training run.

‍

The total cost, including infrastructure, dataset curation, research, and hardware procurement, is significantly higher, speculated to be billions of dollars.

‍

2. They must have broken the rules to do this.

‍

DeepSeek did NOT violate export controls. Instead, they optimized their model architecture to work efficiently with less powerful hardware, staying within legal constraints while maximizing performance.

‍

Particularly, they reduced human-tuning during training and designed their model to work on Nvidia H800 GPUs—less powerful but more accessible than the prohibitive H100/A100 chips.

‍

3. DeepSeek has beaten OpenAI.

‍

DeepSeek’s models excel in cost-effectiveness, offering impressive capabilities at a reasonable cost.

‍

In terms of overall capability, ChatGPT-4-turbo and Gemini 1.5 Pro still lead in reasoning, creativity, and general knowledge, but at higher prices!

‍

4. DeepSeek's models are directly comparable to all other AI models.

‍

Comparisons need to be "apple to apple" while AI models have different specializations.

‍

A fair comparison must be task-specific (e.g., DeepSeek for coding, ChatGPT for creative writing, Claude for safety-focused applications).

‍

5. Deep R1's visible Chain of Thought is a technical breakthrough

‍

Showing reasoning steps in responses is a user interface (UI) choice, not a fundamental AI innovation. The underlying reasoning process is similar to other large language models.

‍

6. DeepSeek built everything from scratch.

‍

OpenAI reportedly has evidence that DeepSeek used model distillation, a process where AI models are trained using outputs from existing models (like ChatGPT), instead of building from the ground up.

‍

7. Using DeepSeek is automatically unsafe.

‍

Security risks depend on usage. If you use DeepSeek’s native app, your data is stored in China. However, self-hosted versions or API deployments can mitigate these risks.

‍

8. This kills Nvidia's business.

‍

‍

DeepSeek’s launch immediately resulted in a market capital decrease for hardware suppliers.

‍

However, in the long run, DeepSeek’s efficiency doesn’t eliminate the need for high-end GPUs but in fact enhances it. More efficient AI models increase overall demand for AI hardware, benefiting companies like Nvidia, AMD, and cloud providers. 

‍

9. This is terrible for US tech companies

‍

Some US tech firms actually benefit from DeepSeek's success.

‍

For example, Amazon’s AWS can host DeepSeek’s open-source models, attracting businesses looking for cost-effective AI solutions.

‍

‍

10. This is China's Sputnik moment in AI.

‍

While DeepSeek is a major achievement, it’s not an overwhelming technological leap ahead of the competition.

‍

A better analogy is Google’s 2004 breakthrough in building efficient infrastructure. Here, DeepSeek demonstrated that you don’t need the most powerful chips to build a competitive product.
