DeepSeek has entered the AI landscape as a strong alternative to ChatGPT, offering an open-source solution with strengths in technical fields, especially coding and mathematics. While ChatGPT remains a dominant force with its well-rounded capabilities and intuitive interface, DeepSeek’s efficiency and cost-effectiveness make it an appealing choice for certain users.

Key Differences Between DeepSeek and ChatGPT

How Their AI Models Work?

DeepSeek uses a Mixture-of-Experts (MoE) model, activating only the necessary parameters for each task to enhance efficiency. ChatGPT, in contrast, employs a standard transformer model that utilises all parameters in every query, ensuring balanced performance.

Performance Strengths and Limitations

DeepSeek stands out in highly technical areas like maths and coding, delivering precise results. ChatGPT excels in contextual awareness and producing detailed, well-structured responses across a broader range of topics.

Cost and Accessibility

DeepSeek, as an open-source model, is freely available for developers and researchers. ChatGPT follows a premium model, offering basic functions for free but requiring a paid subscription for advanced features.

Customisation and Usability

DeepSeek allows greater flexibility for advanced users, making it ideal for those comfortable with AI fine-tuning. ChatGPT, on the other hand, priorities ease of use, providing a seamless experience for casual and professional users alike.

Development Approach

DeepSeek optimises efficiency through innovative training techniques and hardware-friendly deployment. ChatGPT, backed by significant computational resources, follows a more traditional AI development strategy.
