Hi @elevran. Thanks for your PR.

I'm waiting for a kubernetes-sigs member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

Instructions for interacting with me using PR comments are available here. If you have questions or suggestions related to my behavior, please file an issue against the kubernetes-sigs/prow repository.

/ok-to-test

/lgtm

this is indeed much clearer than before.

I suggest to also explain (in a follow up PR) that this example is not a generic way for working with multiple pools, but is just the simplest way when the modelName == poolName.

we should probably make it clear to newcomers that this is usually not the case, cause LoRA adapter name is used as modelName, and typically the adapter name is not the pool name (which often equals to the base model name).
