DeepSeek

DeepSeek is an artificial intelligence research company known for disrupting the frontier model landscape with DeepSeek-V3 and DeepSeek-R1. Built using Multi-head Latent Attention (MLA) and DeepSeekMoE architectures, their models match or exceed proprietary frontier models in software engineering, mathematics, and multi-step reasoning while requiring vastly lower training and inference compute.

DeepSeek-R1 employs large-scale reinforcement learning to develop natural chain-of-thought reasoning without relying on human demonstration data for intermediate steps. Both models are released with open weights under permissive licenses, allowing local deployment via Ollama and vLLM or scalable cloud access via the official DeepSeek API. The API features aggressive prompt caching, making it one of the most economical engines available for complex coding agents and automated research.
