If you're talking about their proxy offering, I had this exact same issue and switched to Portkey. I just use their free plan and don't care about the logs (I log separately on my own). It's way faster (probably cause their code isn't garbage like the LiteLLM code - they had a 5K+ line Python file with all their important code in it the last time I checked).
Virtual Keys is an Enterprise feature. I am not going to pay for something like this in order to provide my family access to all my models. I can do without cost control (although it would be nice) but I need for users to be able to generate a key and us this key to access all the models I provide.
I don’t believe it is an enterprise feature. I did some testing on Bifrost just last month on a free open source instance and was able to set up virtual keys.
agentgateway.dev is one I have been working on that is worth a look if you are using the proxy side of LiteLLM. It's open source part of the Linux foundation.
