What if I told you there’s an AI tool that does almost everything ChatGPT does… for FREE, and costs 90% less than OpenAI for developers?
In January 2025, one AI startup did the impossible. It launched a model that sent shockwaves through Silicon Valley… and wiped 1 TRILLION dollars off US tech stocks in a single day. NVIDIA alone lost $590 billion in market cap overnight.
The name? DeepSeek AI.
And in 2026, it’s bigger, smarter, and more powerful than ever.
Let’s talk about how fast this thing has grown, because the numbers are jaw-dropping.
- Back in August 2024, DeepSeek had about 7,475 visitors per day. A respectable research project, nothing more.
- Then January 2025 happened. DeepSeek-R1 launched. Traffic exploded by 312% in a single month.
- By May 2025, they were getting 22.15 million daily visitors.
- As of March 2026, DeepSeek has reached approximately 125 million monthly active users.
- Their API handles 5.7 billion API calls every single month.
- Their GitHub repository has over 170,000 stars — making it the most popular open-source AI project in the world.
- The app has been downloaded over 57 million times.
And the audience? Largely young people. 44.9% of Android users and 38.7% of iOS users are in the 18–24 age group. This is Gen Z’s AI playground.
In this article, I’m going to break down everything you need to know about DeepSeek, what it is, how it works, its features, pricing, pros and cons, who should use it, and how it stacks up against the competition.
Whether you’re a student, an entrepreneur, or just an AI-curious human, by the end of this article, you’ll know exactly whether DeepSeek is right for you.
Let’s dive in.
WHAT IS DEEPSEEK AI?
So — what exactly IS DeepSeek AI?
DeepSeek is a Chinese AI company founded in 2023 by Liang Wenfeng, the same person behind the quantitative hedge fund High-Flyer. Based in Hangzhou, China, DeepSeek AI started as a research lab with one audacious goal: build world-class AI models… without the world-class budget.
And here’s where the story gets wild.
While OpenAI was spending hundreds of millions of dollars training GPT-4, DeepSeek built DeepSeek-V3, a model that rivals it, for just $5.5 million. That’s roughly 1/18th the cost.
How? By rethinking the architecture from the ground up. Instead of throwing thousands of expensive Nvidia H100 GPUs at the problem, DeepSeek used around 2,000 Nvidia H800 chips and invented smarter training techniques.
The result? A model trained on 14.8 trillion tokens that can process 128,000 tokens at once, which is the equivalent of reading an entire novel in one sitting.
And the kicker? Most of it is open source. You can download and run many DeepSeek models on your own computer for complete data privacy.
DeepSeek AI – Key Features
Okay, so what can DeepSeek actually do? Let me walk you through its biggest features.
DeepSeek AI Chat (The Free Chatbot): This is DeepSeek’s answer to ChatGPT. You go to deepseek.com, sign up for free, and start chatting with the latest model, currently DeepSeek V3.2. No subscription required. No credit card. Unlimited messages with daily reset quotas. For students and everyday users, this is the headline feature.
Chain-of-Thought Reasoning (DeepSeek-R1): DeepSeek-R1 is the reasoning model, think of it like the “thinking” version. Before giving you an answer, it shows its reasoning process step by step. It actually outperformed OpenAI’s o1 model on 2 out of 5 coding benchmarks, including LiveCodeBench, where it scored 65.9%.
DeepSeek-Coder: Developers, this one’s for you. DeepSeek-Coder V2 achieved an 85.6% score on the HumanEval benchmark in 2025 — the gold standard for coding AI. It supports 32 programming languages, from Python and JavaScript all the way to COBOL and Rust. In the first half of 2025 alone, it handled 1.9 billion code-generation queries — a 68% year-over-year jump.
DeepSeek-VL (Vision + Language): This is DeepSeek’s multimodal model — it can understand both text and images. By 2025, it was processing 980 million queries per month, and it’s 1.5x faster than Google’s Gemini in inference speed. Use it for document analysis, OCR, image understanding, and more.
Thinking in Tool-Use (2026 Feature): This is DeepSeek’s newest and most exciting capability. In 2026, their models can now reason BEFORE calling an external API, verify the result against internal logic, and self-correct if something’s wrong. This is a massive leap toward true autonomous AI agents.
Open Weights & Local Deployment: Unlike ChatGPT or Claude, many DeepSeek models are open-weight, meaning you can download them and run them locally using tools like Ollama or LM Studio. Zero data sent to servers. Total privacy. This is huge for businesses handling sensitive data.
128K Token Context Window: DeepSeek can hold 128,000 tokens of context at once. That means it can read an entire legal contract, a full codebase, or a research paper — and still remember every detail of it.
