Description

Adds support for using Vertex AI as an LLM provider in the Replicated install. Users would enter the GCP project id that their service account is in and upload the service account JSON credentials file. They can also specify the GCP location of the service account if it is not the default us-central1.

Replicated config UI:

Proxied gemini 2.5 flash model in LiteLLM proxy is set as the default custom model:

Users can also set direct Vertex AI models instead of a proxied model (they should clear out base URL so requests do not hit the Replicated LiteLLM proxy instance):

Helm Chart Checklist

  • I have updated the version field in Chart.yaml for each modified chart
  • I have tested the chart upgrade path from the previous version
  • I have verified backwards compatibility with existing values.yaml configurations
  • I have updated the chart's README.md if there are any breaking changes or new required values
