A certificate is only a snapshot of somebody’s or somethings state at a certain point in time and the requirements to get certified can be set by whoever is providing the certificate.
In a fast evolving field it would be good for a certificate to clearly state when the state was measured and for how long the certificate is valid.
Personally I don’t perceive this area to move so fast that a basic level of understanding today will be invalid next year. The underlying technology does not change constantly. We are more dealing with a sudden outburst of developments, ideas and concepts on top of these basics that can easily be certified.
A good example would be the course from deeplearning.ai . The content is still valid, useful and applicable across domains providing a good starting point to learn how to use the technology. And the same is true for the basics of how LLMs are build.
So, why not offer a certification program? Especially when covering the basics needed to dive deeper.
