DeepSeek

Definition

A high-performing open-weight AI model family from a Chinese lab, notable for strong reasoning at low cost.

DeepSeek produces open-weight large language models that rival leading proprietary systems on reasoning and coding while being cheaper to run, which has driven wide adoption in third-party assistants and tools. Because the weights are openly available, DeepSeek models can be embedded in many downstream products, spreading whatever brand associations they learned during training. For GEO this matters as a reminder that AI visibility is not confined to a handful of consumer apps - open models propagate a brand's representation across a long tail of interfaces.
