What is DeepSeek?

Chinese AI company offering powerful models at remarkably low prices with strong coding abilities and reasoning capabilities that rival OpenAI and Anthropic.

DeepSeek represents a breakthrough in affordable AI technology, emerging from China as a serious disruptor to Western AI models like ChatGPT and Claude. Unlike expensive alternatives that cost $20-60 per million tokens, DeepSeek offers comparable performance at just $0.14-2.19 per million tokens - up to 95% cheaper than OpenAI's GPT-4. This dramatic cost advantage stems from DeepSeek's innovative Mixture-of-Experts architecture and efficient training methodology, making enterprise-grade AI accessible to startups, smaller companies, and budget-conscious engineering teams worldwide.

The company offers two flagship models: DeepSeek-V3 for fast, general-purpose chat, coding, and question-answering tasks, and DeepSeek-R1 for advanced chain-of-thought reasoning that rivals OpenAI's o1 on math and coding benchmarks. Both models feature 671 billion parameters with a Mixture-of-Experts design that activates only 37 billion parameters per query, keeping inference costs remarkably low. DeepSeek-R1 scored 97.3% on the MATH-500 benchmark and performs competitively on Codeforces, placing it among the top reasoning models globally.
