How to link a virtual key to use specific credentials for a specifc model?

[akraines]

I setup litellm and am trying to configure it for my use case. However after spending considerable time getting things setup I came across what seems to be a major issue: I dont see a way to say that Virtual Key X should Access Models ABC using credentials PQR.
This means that if I have 3 users and each have a different anthropic key for billing purposes, there is no way to use litellm to ensure that when serving User 1 it will serve the anthropic Model using user 1's credentials.

Am I missing something?

This is not supported as of today. @akraines can you share why you want this feature ? is this for your company ?

Thank you for confirming.

Billing and Chargebacks: We have multiple distinct users/teams. We need to use the native billing features of the underlying LLM providers (e.g., Anthropic) to accurately attribute and charge back usage costs to each specific user/team. If all users share one credential, billing reports are aggregated and useless for internal accounting.
