Why build an evaluation program
A single demonstration can mix model capability, prompt quality, tools, and chance. The HARNESS program organizes experiments so these parts can be compared against criteria defined before observing the result.
The verifier’s role
An external verifier checks whether the output follows the protocol, whether data supports the conclusion, and whether the run can be repeated. Invalid and inconclusive results are also recorded because they can expose defects in the instrument and procedure.
Tooling and research are distinct
DeepSeek Harness, or DSH, is an execution tool. HARNESS is the experimental program that defines questions and methods. A successful technical test does not establish a general improvement in intelligence or replace independent scientific evaluation.
