What Is DeepSeek? How to Use DeepSeek AI Effectively

When people mention artificial intelligence, many immediately think of ChatGPT or Gemini, AI tools that are already very familiar to users worldwide. But in this fierce technology race, a new name has appeared and is slowly drawing attention: Deepseek. This AI tool is gaining notice among users for its accurate information processing, in-depth data analysis support and more realistic answers. So what is Deepseek, and how is this AI tool different from the popular AI platforms today? Read on as MONA Media to find the answer below!

What is DeepSeek? The current DeepSeek models

DeepSeek is a artificial intelligence (AI) platform developed by the company DeepSeek, a technology startup based in China. Although it launched only recently, DeepSeek quickly drew attention for its strong natural language processing and its potential to compete with today's leading AI models.

DeepSeek's standout model is DeepSeek-V3, released in 12/2024, using the advanced Mixture-of-Experts (MoE) architecture. DeepSeek V3 is especially strong at content creation, programming and productivity tasks, delivering high-quality output in every respect. On 25/3/2025, an upgraded version of DeepSeek-V3, DeepSeek-V3-0324, was officially released on the AI platform Hugging Face. This update brought significant improvements in reasoning and programming.

Another model that has drawn a lot of attention is DeepSeek R1. Released in 1/2025, DeepSeek R1 is rated as having reasoning and logical thinking comparable to OpenAI o1, but was developed at a much lower cost. Notably, this model has an open license and lets users use for free.

There is now a lot of AI tools launch, and that is also one of the causes of the “FOMO trap”. When many people keep chasing trends and jump into every tool, they lose their direction. According to Huu Hung, Product Director at The MONA, you only need to pick the AI tool that fits your own work. In this video, Hung shares 5 practical lessons for finding the right AI tool, so you do not get swept up in the FOMO spiral!

The DeepSeek AI model is built on the Transformer architecture, with many improvements to optimize computing performance and reduce resource load when deployed. Thanks to these changes, DeepSeek processes information faster and more efficiently while keeping output quality.

Some highlights of DeepSeek's architecture include:

• Mixture of Experts (MoE): This mechanism activates only a small group of the necessary parameters each time a token is generated, reducing computing load without hurting model quality. It works like assigning tasks to the most suitable experts instead of having everyone handle everything. As a result, MoE speeds up processing and improves the model's ability to generalize.
• Multihead Latent Attention (MLA): This technique optimizes self-attention by projecting the Key-Query-Value matrices into a lower-dimensional space, which cuts memory and computing costs.
• Multi-Token Prediction (MTP): Instead of generating one token at a time, the model can produce several tokens in parallel, raising processing performance by 2-3 times.
• FP8 Quantization: FP8 quantization saves up to 75% of memory compared with FP32 without noticeably lowering output quality.

DeepSeek AI is designed with 671 billion parameters, but uses only about 37 billion parameters when generating each token, balancing model size and operating performance. These improvements keep the model running smoothly even on large datasets.

How is DeepSeek different from other AI chatbots?

Comparing DeepSeek with two of the most popular AI tools today, ChatGPT and Gemini, each platform has its own strengths.

• ChatGPT is based on OpenAI's GPT models and stands out for its varied content creation and flexible conversation. 
• Meanwhile, Google's Gemini focuses on creativity and search optimization.

In the comparison table below, you will see how ChatGPT, Gemini and DeepSeek differ, helping you decide which is the best fit for your needs.

What are DeepSeek's standout features?

DeepSeek is an AI with many outstanding advantages, especially in natural language processing and information search. It supports multitasking, from writing and programming to synthesizing knowledge, helping users streamline their workflow. Here are the standout strengths of this AI tool:

Strong performance with optimized resources

DeepSeek is designed to deliver high performance without expensive hardware infrastructure. Instead of relying on GPU as powerful as traditional AI models, DeepSeek optimizes its neural network, reducing the need for computing resources while keeping output quality. 

DeepSeek can be applied flexibly in many fields such as:

• Healthcare: Helps analyze medical records and suggest optimal treatment plans.
• Finance: Predicts market trends and automates trading processes.
• network security: Detects threats and protects systems against attacks.
• Automated systems: Improves the operation of self-driving cars and smart robots.

An AI tool with an open-source, flexible model

DeepSeek is an AI that works on a open-source platformsmodel, letting the community freely fine-tune and upgrade it without being bound by commercial restrictions. This lets the DeepSeek AI tool keep improving to meet many different needs, from scientific research to real deployment in business.

A breakthrough AI development strategy that helps DeepSeek save costs

DeepSeek takes a different path from its rivals by focusing on optimal performance instead of expanding the model size without control. This AI platform has only 671 billion parameters, yet DeepSeek AI still performs well and has a much lower development cost (only about 5.6 million USD), compared with the billions of USD that big tech companies invest in AI. This makes DeepSeek a powerful AI solution that is easier to reach for many businesses and developers.
