Java: Support for the PaLM API in Java

[glaforge]

It would be great if Semantic Kernel supported the PaLM API from Google in Java.
There's the developer focused one here or ideally the Cloud-based one from Vertex AI here.

There are different LLM models available (chat and non-chat), and you can also compute embeddings.

@glaforge we recently add PaLM support apart of microsoft/semantic-kernel#2258 and microsoft/semantic-kernel#2076. Hopefully this helps.

Sorry, I should have been clearer.
It was following a discussion with @brunoborges about the support of PaLM, but in the Java flavor of Semantic Kernel.
Could we reopen this issue?

[nacharya1]

yes course. Appreciate the clarity @glaforge. Thanks for reopening @brunoborges .

Definitely one of the downsides of having all languages in the same repository is that issues may be opened related to one language but reviewed by another language maintainer.

But there are upsides! Let's help users being clarity as they open issues in the future.

This issue is stale because it has been open for 90 days with no activity.

It would also be nice to cover the Vertex AI Gemini models.
