DeepSeek is specializing in the development of large-scale open-source language models. The company unexpectedly grew out of a Chinese hedge fund and disrupted the AI market with its technologies, which significantly reduced the cost of training and inference of LLM models. These technologies include Mixture of Experts - a fragmented model splitting into individual "experts" so that only a small portion of the model could be used for each task. Unlike traditional language models, which rely heavily on supervised fine-tuning, DeepSeek relies primarily on reinforcement learning. It also came up with the idea of using distilled data from OpenAI models for training. DeepSeek provides its online chatbot and an API for business. Its responses are often criticized due to Chinese censorship.
