What is DeepSeek?

DeepSeek took the AI world by storm by matching the reasoning quality of models costing 10x more (its V4 Flash model landed in 2026 at just $0.14 per million tokens) — and giving it away free. The chat app has no usage caps worth mentioning, the R1 reasoning model shows its full thinking process, and the API is so cheap it changed industry pricing. The trade-off: servers can be busy at peak times, and data is processed in China, which matters for some users.

DeepSeek sits in the Chatbots category and is rated 4.6/5.0 by our community — one of the highest-rated tools in its space. It offers a free tier so you can try before you buy.

Best for:
  • Free unlimited everyday AI chat
  • Strong math, coding and reasoning on a budget
  • Developers wanting ultra-cheap API access
Not ideal for:
  • Guaranteed factual accuracy
  • Real-time financial data
