opencode not picking up Google Vertex AI service account json

[sandys]

Description

can you explain how did you use opencode with vertex ? im setting

GOOGLE_APPLICATION_CREDENTIALS=/home/1.json
GOOGLE_CLOUD_PROJECT=abc
VERTEX_LOCATION=global

but when i open opencode, it is just not picking it up. it shows me the default models (anthropic, glm, etc).

Google actively blocks creating api keys if you have enterprise google cloud accounts. there are multiple layers of permission blocks that need to be unblocked before you can create api keys in Google AI studio. it strongly steers towards using service account json.

Opencode would make it so much better if it gave a slightly better experience with setting service account json from within the connect flow.
