Tested OK :heavy_check_mark:

Hi, I have created aibrix cluster following guide -- https://github.com/vllm-project/aibrix/blob/main/development/vllm/README.md ; after that I followed this PR guide to add semantic-router. It's working as expected.

Thanks @Xunzhuo :+1:

[Xunzhuo]

thanks for testing it @nurali-techie

I think the initial version overall looks good to me. I would like to check whether that's helpful to make it part of the release manifest. @googs1025 @Xunzhuo @nurali-techie any ideas?

Integration would be ideal and great! Currently, semantic-router release doesn't seem to have been officially released yet, so we can put integration into the Helm chart or manifest to the next step (perhaps until semantic-router is officially released). For now, we can let users try it out through docs. 😄

@Jeffwan If this PR is part of v0.5.0 release then it's better to mention about semantic-router in release manifest. If need be then we can add "experimental" word, to indicate user that you can "try out" semantic-router with this release and expect more to come in sub-sequent release.

[Jeffwan]

sounds good. v0.5.0 has been cut. We can put it in v0.6.0. Consider @googs1025 has another PR on ai gateway integration. I think it's time to revisit the gateway arch now. I will follow up in slack channel

@Jeffwan true :+1: I am interested to get involved here. Plz tag me in the future discussion whenever possible :pray:

[Jeffwan]

@Xunzhuo did you get a chance to address the comments? I think there're few issues need to be fixed

[Jeffwan]

@Xunzhuo any updates? /cc @googs1025
