Five comparisons · sources linked
As of September 2026
This or that?
Mostly both.
The five comparisons we are asked for most. Same questions on both sides, sources linked, and a short helper that says where to start.
- 01 / 05RAG vs. Fine-tuning
Look it up at question time, or train it in. Cost, latency, freshness, data needs and evals, vendor-neutral.
Buildtechnical - 02 / 05Enterprise assistant vs. your own
ChatGPT Enterprise, Microsoft 365 Copilot or Claude for Work, against building your own. Data, integration, control, cost model, lock-in, compliance.
Buildbuy or build - 03 / 05ISO/IEC 42001 vs. ISO/IEC 27001
The AI management system and the security one. Same structure, different controls, one integrated system.

Roles, impact assessments, transparency, automated decisions, authorities and fines, article by article.
Complylaw · law - 05 / 05EU AI Act vs. ISO 42001
Law or standard: what each asks, where the evidence overlaps, and what applies when.

- 03A start, not a verdict
Each page has a few questions and a recommendation you can add to your void. The first call starts from there.
