The world of Artificial Intelligence is evolving at an incredible pace, with new models and platforms emerging constantly. Among the recent disruptors is DeepSeek, a Chinese AI company that has quickly made waves with its powerful and, notably, open-source large language models (LLMs).
In this article, we’ll dive into the capabilities of the DeepSeek AI chatbot, exploring its potential as a formidable competitor to established players like ChatGPT and Google Gemini. This review is based on a comprehensive demo video that puts DeepSeek to the test across various tasks.

What is DeepSeek AI? Exploring the Open-Source Challenger
Founded in July 2023 and backed by the Chinese hedge fund High-Flyer, Hangzhou DeepSeek Artificial Intelligence Basic Technology Research Co., Ltd. (DeepSeek) launched its eponymous chatbot alongside its DeepSeek-R1 model.
What sets DeepSeek apart is its commitment to an open-source AI chatbot approach (specifically, “open weight” under the MIT License), making its models and code accessible to the public. This fosters transparency and allows developers to build upon their technology. Furthermore, DeepSeek has demonstrated remarkable cost-efficiency in model training. They reportedly trained their V3 model for significantly less than the cost of training models like OpenAI’s GPT-4 or Meta’s Llama 3.1, achieving comparable performance with a fraction of the computing power. This innovative approach is already being described as “upending AI.”
The DeepSeek.com chatbot serves as an accessible interface to interact with these powerful models, offering a user experience similar to other popular AI chatbots.
To get a real feel for DeepSeek’s capabilities, check out the video demo below:

Putting DeepSeek to the Test: Capabilities Demonstrated
The demo video explores DeepSeek’s versatility by presenting it with a range of challenging tasks:
Handling Complex Scientific Queries
The demo begins by asking DeepSeek about intricate scientific concepts, specifically:
- Terraforming Venus: A highly complex, hypothetical engineering and scientific challenge.
- The Deep Biosphere: Discussing life existing kilometers below the Earth’s surface or ocean floor.
DeepSeek provided detailed and well-structured answers to both questions, demonstrating a strong grasp of complicated scientific topics. The ability to generate such comprehensive outputs highlights its potential as a valuable tool for learning and research.


Summarizing Information Efficiently
One of the most practical applications of AI chatbots is summarization. The video tested DeepSeek’s ability to quickly condense lengthy text:
- Job Postings: Summarizing detailed job descriptions from different global locations (Australia and Hong Kong). This showcased its ability to extract key information like role, location, required skills, and company.
- Book Chapters: Summarizing chapters from classic and philosophical texts (‘Alice’s Adventures in Wonderland’ and ‘Meditations’ by Marcus Aurelius). Even if the models were likely trained on these famous works, the quality of the summary and the inclusion of themes/quotes were impressive.
This summarization capability underscores a major benefit of using AI like DeepSeek: it can massively speed up your productivity by quickly processing and distilling information, saving significant time and effort.


Providing Actionable Advice: Default vs. DeepThink (R1)
A particularly insightful part of the demo involved asking for job search advice for a data analyst role. The same detailed query was posed to two different DeepSeek models available on the platform: the default model and the more advanced DeepThink (R1) model.
The query asked about:
- Getting a role within three months.
- Whether to use the same resume or customize it.
- Whether to apply broadly or only to interesting jobs.
Both models provided valuable tips, but the DeepThink (R1) model offered a more nuanced and strategic approach. It recommended a hybrid resume strategy (master resume + customizing the top 25-50%) and a split application strategy (60% targeted, 40% high-volume quick applications), along with concrete numbers (aim for 10-15 quick applications a day). This comparison demonstrated the difference in reasoning and depth between DeepSeek’s various models and the capability of its advanced models to provide sophisticated, actionable advice.
While a direct deepseek vs chatgpt comparison on this specific query wasn’t performed, the quality and structure of DeepSeek’s advice, particularly from the R1 model, shows it is a strong contender capable of generating outputs comparable to other leading LLMs. The “thinking” process displayed by the DeepThink model before generating its response was also an interesting feature.


Key Features and Benefits of DeepSeek Chatbot
Based on the demo and background information, here are some standout features and benefits:
- Open-Source/Open-Weight Models: Provides transparency, allows community contribution, and enables developers to download and run models locally (benefit: accessibility, flexibility).
- Powerful Capabilities: Handles diverse tasks including complex questions, summarization, and generating advice (benefit: versatility, useful for many applications).
- Efficient Performance: Demonstrates fast response times for summarization and query answering (benefit: increased productivity, saves time).
- Multiple Models Available: Offers choice, including the advanced DeepThink (R1) for more complex reasoning (benefit: caters to different user needs and task complexities).
- Quality Output: Provides well-formatted, detailed, and often insightful responses, including markdown formatting for easy copying and use elsewhere (benefit: professional results, easy workflow integration).
- Cost-Effective Development: DeepSeek’s efficient training methods promise continued innovation and potentially accessible pricing or usage models in the future (benefit: sustainability, potential affordability).
DeepSeek’s Place in the AI Landscape
DeepSeek’s arrival marks a significant moment for open-source AI. By releasing powerful models under permissive licenses and demonstrating efficient development practices, they offer a compelling alternative to proprietary systems. This encourages competition, drives innovation, and provides users and developers with more options in the rapidly evolving AI landscape.
Conclusion: DeepSeek is a Serious AI Contender
The DeepSeek AI chatbot, powered by the company’s innovative and cost-effective open-source models, proves to be a highly capable and versatile tool. From tackling complex science questions and efficiently summarizing text to providing strategic advice using its advanced DeepThink model, DeepSeek demonstrates performance comparable to other top-tier AI chatbots.
For anyone interested in exploring powerful open source ai chatbot options or evaluating contenders in the AI space, the DeepSeek chatbot is certainly worth investigating. As this deepseek ai chatbot review shows, it’s not just another AI; it’s a potential game-changer shaping the future of accessible, powerful artificial intelligence.
