What is DeepSeek?

DeepSeek is a cutting-edge generative AI platform – essentially a chatbot and a family of large language models (LLMs) developed in China – comparable in capability to OpenAI’s GPT-series. It was created by an AI research company based in Hangzhou and first launched in 2023. From the start, DeepSeek’s mission has been to make advanced AI more efficient, accessible, and open. Unlike many proprietary AI systems, the DeepSeek team releases several of its models under open licenses, meaning developers and researchers can actually download and experiment with the AI themselves.

In early 2025, DeepSeek attracted global attention with the release of DeepSeek-R1, a reasoning-focused AI model designed to perform complex analytical and problem-solving tasks. The model was released with open weights, enabling researchers and developers to study and experiment with advanced reasoning capabilities. Alongside its research models, DeepSeek provides a chatbot service that allows users to interact with its AI through a web interface and mobile applications.

Today, the term “DeepSeek” can refer both to the company’s family of AI models and to the platform used to access them. DeepSeek’s ecosystem includes hosted services (web, app, and API) as well as selected open-weight models released for research and development use. Together, these components make DeepSeek a widely discussed AI platform known for strong reasoning capabilities, developer-friendly tools, and multiple ways to access its models.

Official Ways to Access DeepSeek

DeepSeek offers several official channels for users and developers to access its AI models:

• DeepSeek model (currently V3.2) without any installation. This is the quickest way to try DeepSeek’s capabilities firsthand for Q&A, content generation, etc. (DeepSeek offers free access through its web chat and mobile app. Availability and account requirements may vary depending on the product and region.)
• DeepSeek Mobile App: A smartphone app that brings the DeepSeek AI assistant to your device. Available on major app stores (for iOS and Android), the app offers on-the-go access to the same AI model with a chat-friendly interface. The DeepSeek mobile app provides access to the AI assistant on smartphones through official app stores. The mobile app is ideal if you want a ChatGPT-like experience on your phone, with features like voice input and chat history.
• DeepSeek API Platform: A cloud API for developers and businesses. By creating a free account on the DeepSeek Platform, developers can integrate DeepSeek’s language model into their own applications via RESTful API calls. The API provides both a standard fast model and a “reasoning” model, with support for 128K context windows, and features such as tool usage and JSON-formatted outputs. Pricing is pay-as-you-go and extremely competitive – you only pay for the tokens your application uses. This makes it easy and cost-effective to add advanced AI capabilities to your software.
• Open Model Downloads: For advanced users, DeepSeek also releases certain models openly. This means you can download the trained model weights from official sources (such as DeepSeek’s GitHub) and run the AI on your own hardware. DeepSeek-R1 has been released with open weights under the MIT license. Other DeepSeek models such as V3 may have different licensing terms depending on the repository and distribution. Self-hosting a DeepSeek model requires significant computing resources (especially for the largest models), but it offers maximum control — useful for researchers or organizations needing a private deployment.

DeepSeek Models at a Glance

DeepSeek has developed a range of AI models, each with different strengths. Here are the main DeepSeek models you should know about:

• DeepSeek-V3.2 (latest): The current flagship general-purpose model (released late 2025). DeepSeek-V3.2 is a state-of-the-art LLM that supports an enormous 128,000-token context window, meaning it can analyze or generate extremely long documents in one go. It’s designed for versatility – from answering questions and writing content to complex reasoning. (V3.2 introduced efficiency improvements and can operate in a special “deep reasoning” mode for complex queries.)
• DeepSeek-R1: A breakthrough reasoning-optimized model released in January 2025 under an open-source license (MIT). Built on the V3 architecture, R1 excels at logical reasoning, math, and problem-solving tasks. It made headlines for delivering GPT-4-level performance on many benchmarks while being trained for under $6 million. R1 powers DeepSeek’s chatbot to provide more accurate and well-reasoned answers. (This model’s open release greatly expanded DeepSeek’s community adoption.)
• DeepSeek-V2: The second-generation model launched in mid-2024, which first introduced the 128K context length and more advanced training techniques to cut costs. DeepSeek-V2 (and a lighter “V2-Lite” variant) improved upon the original model in both English and Chinese performance. While largely superseded by V3 now, V2 is still notable for being a robust model and is available for use (particularly if you need a slightly smaller model).
• DeepSeek Coder: A specialized model series tailored for programming assistance. The original DeepSeek-Coder (released Nov 2023) was one of the first open models from the company, aimed at code completion and debugging. DeepSeek Coder V2 includes models such as 16B and 236B parameter variants and supports context lengths up to 128K tokens. These models are trained on large volumes of code and can generate functions, fix bugs, and explain code in multiple languages (like Python, Java, etc.).
• DeepSeek Math: A specialty model fine-tuned for mathematics and logical problem solving. DeepSeek-Math is designed to tackle math word problems, algebra, calculus, and even logic puzzles by following step-by-step reasoning. It was trained on a blend of math datasets (including research papers and coding challenges) to excel at tasks that require calculations or formal reasoning. For users in education or research, this model provides more reliable solutions in math-related queries than the general model.
• DeepSeek-VL (Vision-Language): A research-oriented multimodal model designed to process both images and text. DeepSeek-VL enables tasks such as image description, visual question answering, and generating text responses based on visual inputs. The model represents DeepSeek’s early work in combining vision and language capabilities within a single system. In parallel, the DeepSeek research team has also explored related multimodal projects such as the Janus series, which investigate image-understanding and generation techniques. While these vision models are primarily part of the company’s research ecosystem and are not yet a core feature of the public DeepSeek chatbot, they highlight DeepSeek’s ongoing development of multimodal AI technologies.

Why People Use DeepSeek

What makes DeepSeek stand out in the crowded AI field? Here are some key reasons users and developers are turning to DeepSeek:

• High-End Performance: DeepSeek’s models are cutting-edge. In independent tests, the latest versions (like V3.2 and R1) perform on par with some of the best from OpenAI and Anthropic. They excel at complex reasoning, coding tasks, creative writing, and bilingual conversation. In practice, this means you can ask DeepSeek to draft an article, debug code, or solve a tricky problem and get results comparable to what top-tier AIs would produce.
• Low Cost & Free Access: DeepSeek is far more affordable to use than many competitors. The web chat and app are free for anyone to experiment with. For heavier use, the API’s pricing is extremely low – on the order of a few cents for thousands of tokens. (For example, generating a lengthy essay or analyzing a large dataset might cost pennies, not dollars.) This low barrier to entry allows students, indie developers, and small businesses to leverage a GPT-4-class model without breaking the bank. (See our [DeepSeek Pricing] page for a detailed cost breakdown.)
• Open & Flexible: Unlike closed platforms, DeepSeek provides an open-source pathway. The company has released model weights openly, which means the AI community can fine-tune DeepSeek models for specialized needs or even run them offline. This openness not only builds trust (you can inspect how the model works) but also spurs innovation – researchers have already created custom variants and improvements thanks to access to DeepSeek’s code. If you prefer not to be locked into a proprietary API and want more control, DeepSeek’s open model ethos is a huge plus.
• Long Context & Advanced Features: DeepSeek models support context windows up to 128K tokens depending on the model variant. Practically, this means it can ingest or generate very large documents (hundreds of pages) in one go, maintaining context the whole time – great for tasks like analyzing lengthy reports or having an in-depth conversation without forgetting earlier details. Additionally, DeepSeek offers advanced features for power-users: it can return answers in structured formats like JSON, it can perform tool use (e.g. call external APIs or functions when integrated in an agent framework), and it has a special “thinking mode” for more complex queries that require chain-of-thought reasoning. These capabilities make DeepSeek not just an API for short chats, but a versatile AI toolkit.
• Bilingual & Versatile: DeepSeek was trained on a massive dataset in both English and Chinese, making it truly bilingual. It can seamlessly switch between languages or handle multilingual input, which is a strong advantage for global users. Beyond language, people use DeepSeek for a wide range of use cases: from drafting emails and stories, to answering technical questions, writing code, tutoring in various subjects, and more. Its specialized offshoots (like Coder and Math) further extend its utility in specific domains. Whether you need a creative writing partner, a coding assistant, or a research helper, DeepSeek has a model or mode geared for that purpose.
