I am seeing a lot of demand for something like a semver for AI models.

Could thereotically there could be something like a semver that can be autogenerated from that defined and regular version scheme that you shared?

Like, Honestly my idea of it is that I could use something like openrouter and then just change the semver without having to worry about these soooo many things as the schema that you shared y'know?

A website / tool which can create a semver from this defined scheme and vice versa can be really cool actually :>

I'm not sure if this is a joke or not, but in case it isn't: Semver was mostly created so users of libraries could judge if a new release would break the API interfaces or not, by just looking at the version. So unless the first number changed, you're good to go (in theory, in practice this obviously didn't work as expected).

With that in mind, what exactly would semver (or similar) represent for AI models? Setup the proper way, your pipelines should continue working regardless of the model, just that the accuracy or some other metric might change slightly. But there should never be any "breakages" like what semver is supposed to help flag.

Models have changes worthy of semver style major changes. Tokenizer, tool support, tool format, JSON modes, etc. Pipelines absolutely must change when these change.

This thread is more about the minor number: not incrementing it when making changes to the internals is painful for dependency tracking. These changes will also break apps (prompts are often tuned to the model).
