Open-weight AI still lacks regulation; vendor report proposes six-stage process first

Z.ai and Beijing-based safety consultancy Concordia AI released a report on open-weight AI risk management on Monday, proposing a six-stage management process that they called the first comprehensive, evidence-based foundation for the field.

Open-weight models are those whose trained parameters can be freely downloaded, modified, fine-tuned and run independently by anyone, so once released the developer cannot control how they are used the way closed-model labs can — which is exactly what makes risk management hard.

The report is a proposal from a model developer and a consultancy, not a regulation; the South China Morning Post's account does not list the six stages, so how it would work in practice awaits the full report and any regulatory follow-up.
