DeepSeek is an emerging family of open-source large language models (LLMs) designed for coding, reasoning, and research applications. Positioned as an alternative to closed-source systems like ChatGPT (OpenAI), Claude (Anthropic), and Gemini (Google DeepMind), DeepSeek emphasizes performance, transparency, and accessibility.
This review explores DeepSeek’s strengths, limitations, use cases, and how it compares with industry leaders.
DeepSeek is a state-of-the-art open-source AI project built to provide developers and researchers with powerful, transparent LLMs. Unlike proprietary AI assistants, DeepSeek models are openly available, making them customizable, auditable, and deployable across different infrastructures.
