Hello @Feiyang1, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

Summary of Changes

Hello! Gemini here, providing a summary of this pull request. This PR, authored by Feiyang1, aims to update the default model name used in the predict-text-embeddings.js snippet. The change specifically updates the hardcoded default value for the model parameter in the main function to reflect the new model name, gemini-embedding-001, replacing the previous text-embedding-005. This ensures the sample code is up-to-date with the latest model naming conventions.

Highlights

• Model Name Update: The primary change is updating the default embedding model name used in the ai-platform/snippets/predict-text-embeddings.js sample.

Changelog

• ai-platform/snippets/predict-text-embeddings.js
  • Updated the default value for the model parameter in the main function from text-embedding-005 to gemini-embedding-001 (line 23).

Code Review

This pull request updates the default model name in the predict-text-embeddings.js snippet to gemini-embedding-001. The change is simple and clear. My primary feedback revolves around ensuring that this new default model behavior is covered by the existing test suite.

Summary of Findings

• Test Coverage for New Default Model: The new default model gemini-embedding-001 in predict-text-embeddings.js may not be covered by the existing test suite. Current tests appear to explicitly specify a model, thereby bypassing the default. It's recommended to add a test case to verify the script's functionality when relying on this new default model.

Merge Readiness

This pull request makes a simple update to the default model name. The code change itself is clear. However, there's a medium-severity concern regarding test coverage for this new default model. It is recommended to add a test case that specifically verifies the script's behavior with gemini-embedding-001 as the default before merging this PR. As an AI, I am not authorized to approve pull requests; this assessment is based on the review. Due to the testing concern, I recommend addressing this before merging.

Older ai-platform-snippets test failed, but unsure why newer tests skipped. May be issue with samples pending migration.

[gericdong]

@Feiyang1: the integrated test of this repo doesn't support fork. I'd suggest not to use a fork and then submit a new PR.

[glasnt]

I'm trying to migrate the ai-platform samples in #4100 with minimal success.

I can successfully run these tests on my local machine.

I'll create a branch to confirm the tests work with the old testing method, but I believe we should merge this PR as is to unblock this update
