Model selection is the first major technical decision in the AISDP lifecycle. The choice of model architecture determines the system’s compliance profile across six criteria: documentability, testability, auditability, bias detectability, maintainability, and determinism. This section covers the full evaluation process, from candidate architecture assessment through to the formal Model Selection Record.

The evaluation begins with a full-spectrum review of candidate architectures, spanning heuristic systems through to foundation models. It then addresses model origin risk for open-source and commercial components, copyright and IP exposure, the fine-tuning provider boundary under Article 25, and the six compliance criteria scored against each candidate. The section concludes with the artefacts produced: the Model Selection Record, origin risk assessments, IP analysis, provider boundary determination, and the compliance criteria scoring matrix.

Note:

This section corresponds to the Model Selection section and feeds primarily into AISDP Modules 2 (Development Process) and 3 (Architecture and Design).
