DeepSeek is a family of neural networks from the Chinese company DeepSeek — the one that made the market recalculate the cost of artificial intelligence in early 2025, when its models matched Western flagships at a fraction of the price.
The family answers questions and writes and edits text, but it is best known for code and reasoning: the model can think a hard task through and reach the answer via intermediate steps. The current models hold up to a million tokens in context — a folder of documents or an entire project at once. The weights are published under a free licence, so DeepSeek can also be run on your own hardware.
DeepSeek models are available in GPTunneL — worldwide, without a VPN, with one balance and billing for the tokens you actually spend.
