Original Pull Request: https://github.com/anomalyco/opencode/pull/11020

State: closed
Merged: Yes

Fixes #7514

Problem

When switching between different providers on Vertex AI (e.g., from an Anthropic model to a Gemini model), the SDK cache would return the wrong cached instance. This caused incorrect API URLs like:

https://aiplatform.googleapis.com/v1/projects/.../publishers/anthropic/models/gemini-3-flash-preview:streamRawPredict

Root Cause

The SDK cache key was computed using only { npm, options }, but both google-vertex and google-vertex-anthropic providers share the same npm package (@ai-sdk/google-vertex) with similar options (project, location).

Solution

Include providerID in the SDK cache key:

// Before
const key = Bun.hash.xxHash32(JSON.stringify({ npm: model.api.npm, options }))

// After
const key = Bun.hash.xxHash32(JSON.stringify({ providerID: model.providerID, npm: model.api.npm, options }))

Verification

Tested by switching between Anthropic and Gemini models on Vertex AI - each now correctly uses its own SDK instance with proper publisher URLs.
