feature: LLM Tracing, tracking token usages and access control in kubeai

[meetzuber]

Hi

I came to know about kubeAI its very nice integration of GenAI tools. only access control and usages tracking is missing which is also a important part of LLMOps.

deploying langfuse instance and logging all metrics and tokens in langfuse with user details will be a good idea.

1. litellm or any other application can be used for sending traces to langfuse, loadbalancing, model failover etc.
2. user management can be done by litellm or open-webui, where users can create there own tokens and use them.
3. using this Billing can be done based on token used by team/user.
4. daily/monthly budget or limits can be set using litellm.

Tools mentioned above are just for reference which I use, but can be replaced with any other tool which will be stable and easy to integrate in exiting framework.

Thanks :)
