Overview

DeepSeek Harness is an MIT-licensed framework where "everything is a plugin"—models, datasets, optimizers, evaluators, and routing logic can be swapped independently. It is aimed at building and benchmarking DeepSeek and other LLMs with a consistent interface for training, inference, and evaluation. Developers should care because it reduces glue code in LLM experiments and makes it easier to compare models under identical pipelines.
