Acerca de DeepSeek

DeepSeek is an AI lab and assistant platform known for its open-weight model family — most notably the DeepSeek-V3 and DeepSeek-R1 reasoning models — which deliver performance competitive with frontier closed models at a fraction of the cost. The DeepSeek chat assistant (chat.deepseek.com) gives free access to these models with a "DeepThink" reasoning mode. Because the weights are open, DeepSeek models are widely self-hosted and have become a default choice for cost-conscious developers.

Nuestro veredicto

The open-weights value champion — DeepSeek delivers frontier-grade reasoning at radical low cost, making it the go-to for cost-sensitive and self-hosted setups.

Preguntas frecuentes

Is DeepSeek really free?

The DeepSeek chat assistant is free to use, and the underlying model weights are openly available. The API is paid but dramatically cheaper than most frontier-model APIs.

Are DeepSeek models open source?

DeepSeek releases model weights openly (DeepSeek-V3, DeepSeek-R1) under a permissive license, allowing self-hosting. This makes them popular for cost-sensitive and private deployments.

How does DeepSeek compare to GPT-4 or Claude?

On many reasoning and coding benchmarks, DeepSeek-R1 is competitive with frontier closed models, while costing far less via API. It is less multimodal and has a smaller surrounding product ecosystem.
