📄 Description

feat: Optional user metadata forwarding to LiteLLM for cost tracking

Description

This PR introduces an opt-in feature to forward user metadata to LiteLLM for enhanced cost tracking. A new environment variable enables the inclusion of additional user information in the payload sent to LiteLLM Proxy.

Changes

  • Added new environment variable ENABLE_FORWARD_USER_INFO_LITELLM_TAGS in env.py
  • Implemented logic to include user metadata in payloads when enabled
  • Modified payload structure in routers/openai.py, routers/audio.py, routers/image.py, and retrieval/utils.py

Metadata Details

When enabled, the following tags are included:

  • Source: openwebui
  • Model name
  • User email
  • User name

Implementation

  • The feature is opt-in, requiring explicit activation via the environment variable
  • Payload structure now includes a metadata object with a list of 'tags' when enabled

Testing

  • Conducted comprehensive testing with various user scenarios to ensure accurate metadata generation and transmission

Privacy Considerations

  • Feature is disabled by default to maintain user privacy
  • Only activates when ENABLE_FORWARD_USER_INFO_LITELLM_TAGS is set

Screenshots

User Metadata Forwarding

Impact

This feature enhances cost tracking capabilities through LiteLLM while maintaining user privacy as an opt-in feature.
