How DeepSeek and ChatGPT are Reshaping AI in 2025

Is This the End of ChatGPT's Reign as the Best AI Language Platform? Early 2025 started with a bang in the conversational AI landscape with the arrival of DeepSeek, an AI platform from China that has entered the race to challenge ChatGPT and redefine the rules of the game.

Just days after its public launch and rapid adoption, DeepSeek shook the international market, causing shares of major companies like chip manufacturer Nvidia to drop by 13%, wiping hundreds of billions of dollars off its market value.

In this article, we explore DeepSeek's origins and how this Chinese AI language model is transforming the market, whilst analysing its advantages and disadvantages compared to ChatGPT. Are we close to witnessing a technological war? Who will win this battle? Keep reading to draw your own conclusions.

The Rise of the Challenger

DeepSeek is an AI language model that emerged in 2023 as an open-model project. Its philosophy centres on free access to artificial intelligence, unlike ChatGPT, which was developed by OpenAI with a more commercial approach.

DeepSeek has garnered significant attention for several reasons. One striking factor is that its training took just two months and cost approximately 6 million dollars, whilst ChatGPT's development is estimated to have required between 500 million dollars and several million more.

Another noteworthy characteristic of DeepSeek is its open-source nature, an aspect we shall explore in detail later.

DeepSeek's progress has been sailing smoothly, marked by significant milestones:

• Initial launch with capabilities comparable to commercial models like ChatGPT

• Implementation of innovative language processing architectures, including the MoE (Mixture of Experts) structure, Multi-head Latent Attention (MLA), and Multi-token Prediction (MTP)

• Development of specific tools for different industrial sectors

• Continuous integration of community-driven improvements, thanks to its open architecture philosophy

DeepSeek is rapidly gaining popularity due to its transparency and accessibility, reflecting the need for inclusive and collaborative AI solutions.

Detailed Comparative Analysis

DeepSeek has emerged as a formidable competitor to ChatGPT by introducing an innovative perspective in the field of AI language models. This open-access software alternative particularly excels in technical and mathematical areas, whilst ChatGPT maintains its position with proven versatility and an intuitive interface.

Below are the fundamental differences:

Architecture and Performance:

DeepSeek utilises a Mixture of Experts (MoE) approach with 671 billion parameters, selectively activating only the most relevant ones for each task. In contrast, ChatGPT employs a traditional transformer model that processes all tasks uniformly. This architectural difference enables DeepSeek to achieve 90% accuracy in mathematical tasks, significantly outperforming its competitors.

Accessibility and Costs:

DeepSeek: Free and open-source, allowing community modifications
ChatGPT: Freemium model with premium features under subscription

Key Strengths:

DeepSeek:

• Excellent performance in technical and mathematical tasks

• Faster structured responses

• High customisation for technical users

• Resource efficiency

• Superior cost-effectiveness

ChatGPT:

• Better contextual understanding

• More user-friendly interface

• More nuanced responses

• Robust privacy compliance

• Superior multimodal capabilities

Ideal Use Cases:

DeepSeek is the perfect choice for:

• Developers and technical users

• Projects requiring mathematical precision

• Teams with limited budgets

• Advanced customisation needs

ChatGPT excels in:

• Enterprise environments

• General content creation

• Non-technical users

• Projects requiring high privacy

The choice between these platforms primarily depends on the user's specific needs: DeepSeek stands out in technical performance and cost-effectiveness, whilst ChatGPT offers a more polished and versatile experience. Both tools continue to evolve, enhancing their capabilities and defining the future of human-AI interaction.

The Open Source Revolution

One of DeepSeek's striking features is its shared code system philosophy, where anyone can access, modify, and improve its technology. This fosters global collaboration where developers can adapt the model to specific needs or even enhance its capabilities.

This stands in contrast to ChatGPT's proprietary model which, although offering an API (Application Programming Interface), keeps its base code inaccessible to the public and restricts users from modifying it or understanding its internal workings.

• Benefits for Developers: Programmers can experiment without restrictions, leading to the creation of innovative tools and customised solutions.

• Democratisation of AI: Small businesses and non-profit organisations can now leverage advanced technologies without incurring prohibitive costs.

• Use Cases: From medical applications to educational solutions, DeepSeek is expected to be utilised in projects across various sectors that were previously unthinkable with proprietary models.

Market Impact and Future Outlook

DeepSeek has caused a significant impact in the technology industry by demonstrating its ability to develop AI models at lower costs than established competitors like OpenAI and Google. Remarkably, the company achieved this breakthrough despite US restrictions on advanced chip exports, efficiently optimising the use of available GPUs.

This achievement represents a direct challenge to Nvidia's market dominance, as it demonstrates that high performance is achievable with less sophisticated hardware. This could motivate other developers to optimise lower-cost hardware, affecting Nvidia's revenue streams.

Despite these promising advances, questions arise about the competitive sustainability of DeepSeek's cost-effective model, considering that American tech giants continue to invest billions in AI infrastructure and build massive computing clusters, which could widen the resource availability gap.

Conclusion

DeepSeek has arrived to change the rules of the game in AI evolution, demonstrating that it's possible to develop advanced models efficiently and economically through open source. Its success challenges the hegemony of major American technology companies and presents a more democratic and accessible platform.

In the coming years, we're likely to witness two paths in the AI market: on one side, large companies like OpenAI and Google will continue developing highly sophisticated proprietary systems, focused on enterprise clients and specialised applications. On the other side, a robust ecosystem of collaborative development solutions inspired by the DeepSeek model will emerge, democratising AI access for developers, small businesses, and emerging markets.

This philosophical duel will likely drive greater innovation in both sectors, potentially benefiting corporate users and the development community alike, whilst optimising computational resources and reducing implementation costs.
