Google Gemini Embeding - recommended articles

I have searched intensively but have not found the answer. We have a community in Czech language, and I would like to give it a list of recommended articles at the bottom of the page.

It seems that Gemini may be a good choice for our Czech language. But I haven’t found a comprehensive guide on how to make Gemini embeding work on your own hosting.

We would like to use the Gemini model later for other AI features as it offers sufficient quality at a very reasonable price.

Is there anyone here who has the same intention?
Or does some other free seem like better, for our type of use?
