DeepSeek: review, test, pricing and alternatives (2026)
The low-cost frontier LLM: free chat and a very cheap API.
DeepSeek — The low-cost frontier LLM: free chat and a very cheap API. Those who want a powerful, very cheap LLM, especially via the API. Editorial rating: 4/5 (Recommended).
What is DeepSeek?
DeepSeek is the outsider that shook the whole sector. This Chinese lab showed you could reach performance worthy of the top models — notably on reasoning and code — for a fraction of the cost, and it released open weights to boot. Enough to reshuffle a market where raw power was assumed to be reserved for a few heavily-funded giants.
In practice, you get a free web chat for daily use, and above all an API among the cheapest on the market at comparable capabilities. That performance-per-dollar ratio is what makes it a favorite for developers: prototyping, embedding an LLM in an app, or processing volume without watching the bill explode.
Two points deserve a clear-eyed look. The ecosystem of apps and integrations around DeepSeek is smaller than ChatGPT's. And depending on your use — especially for sensitive or business data — hosting and the privacy policy are worth assessing (the servers and legal framework differ from Western players'). Versions and pricing change fast: check the current state on the official docs.
