What Is Gemini Code Assist Code Review?

Gemini Code Assist code review is Google’s AI pull request (PR) reviewer for GitHub. Once installed on a repository, the Gemini Code Assist app reviews each new PR with Gemini models, posts severity-ranked comments with suggested fixes, and answers /gemini commands in the PR conversation.

In October 2026 it runs through an enterprise version installed from Google Cloud, after Google retired the free consumer app.

What Changed in Gemini Code Assist Code Review in 2026

Trend: Gemini code review on GitHub moves to an enterprise version

• The free consumer GitHub app has shut down. Installs stopped on June 18, 2026 and all code review activity from the consumer app ended on July 17, 2026; the enterprise version wasn’t affected (July 2026, Google’s deprecation notice).
• GitHub reviews now run only through the enterprise version, which is still in Preview. Google describes it as a separate product from Gemini Code Assist Enterprise, installed through Google Cloud (last checked October 2026, Google’s docs).

Trend: Gemini Code Assist subscriptions wind down

• New Gemini Code Assist Standard and Enterprise subscriptions are no longer on sale. The change covers the IDE and CLI subscriptions: existing ones keep working, annual renewals and added licenses end on January 31, 2027, monthly renewals end on December 31, 2027, and Google points teams to Antigravity in Gemini Enterprise. Google’s docs treat the enterprise GitHub reviewer as a separate product (October 2026, Google Cloud docs).

How Gemini Code Assist Code Review Works

Gemini Code Assist Review Flow on a New Pull Request

Each new PR goes through the same flow:

1. When the PR opens, gemini-code-assist[bot] is added as a reviewer.
2. It posts a review comment in the Conversation tab.
3. It posts inline comments on changed lines.

Each comment carries a severity (Critical, High, Medium or Low), an explanation, a code suggestion that can be committed from GitHub and, where relevant, a reference to the team’s style guide.

Gemini Code Assist Commands in the Pull Request

Gemini Code Assist Review Configuration

A .gemini/config.yaml file in the repository root controls behavior: the minimum comment severity (Medium by default), a cap on the number of comments, glob patterns to ignore, whether to review draft PRs and whether to post a summary when a PR opens. A .gemini/styleguide.md file holds the team’s review rules in plain language.

Groups of repositories can share settings from the Google Cloud console, and a repository’s own config.yaml overrides the group (last checked October 2026, Google’s configuration docs).

Gemini Code Assist Setup Requirements

The enterprise version needs three things, in this order:

1. Create a Google Cloud project with a billing account.
2. Grant the right IAM roles.
3. Create a Developer Connect connection, which Google always creates in the us-east1 region.

It supports GitHub, GitHub Enterprise Server and GitHub Enterprise Cloud.

What to Know Before Relying on Gemini Code Assist for Review

Gemini Code Assist Reviews GitHub Pull Requests Only

Google’s docs describe GitHub hosts only. Teams on GitLab, Bitbucket, Azure DevOps or Gerrit need a different reviewer, such as the options covered in GitLab merge request review and Azure DevOps code review.

Gemini Code Assist Skips Some Files and Comments by Design

Gemini Code Assist doesn’t summarize or suggest changes for files in .github/workflows. Comments below the severity threshold aren’t posted, so a Medium threshold hides Low-severity findings.

Gemini Code Assist Subscription Path Is Changing

With new Standard and Enterprise subscriptions closed and renewals ending in 2027, teams that standardized on Gemini Code Assist need a plan for where coding assistance will run next. Google hasn’t announced an end date for the enterprise GitHub reviewer (as of October 2026).

Merge Decisions on Gemini-Reviewed PRs Stay With People

Like other AI reviewers that ship with a coding tool, such as GitHub Copilot code review and Cursor code review, Gemini Code Assist comments on the PR. Branch protection and human approvals decide what merges.

Qodo’s Take: Keep Code Review Independent of the Coding Assistant

Google’s 2026 changes show how quickly a coding assistant’s packaging can move.

A team that kept its review rules in one assistant’s config has to rebuild them each time the tool or the plan changes.

Review works better as its own layer, with the team’s standards in one place, run by a separate system that didn’t write the code, on every Git provider the team uses.

Qodo is that layer. Qodo is the best AI code review platform for teams using Gemini Code Assist because review stays independent of the assistant’s roadmap: as Google winds down Gemini Code Assist subscriptions and moves GitHub review to a separate enterprise product, Review Standards and PR review stay the same on GitHub, GitLab, Bitbucket, Azure DevOps and, on Enterprise plans, Gerrit, applied once Rule enforcement is on.

Qodo Review Standards Carry the Team’s Rules Across Tools

Qodo imports rules from the instruction files teams already keep, including GEMINI.md, AGENTS.md, CLAUDE.md and .cursor/rules/, into one place, its Review Standards (last checked October 2026, Qodo’s docs). When the team moves from one coding assistant to another, the standards stay where they are.

Qodo Reviews on Every Git Provider and Deployment Model

Qodo reviews PRs on GitHub, GitLab, Bitbucket, Azure DevOps and Gerrit, with multi-tenant, single-tenant and on-premises deployment, so the review doesn’t depend on one cloud or one host.

Qodo Context Engine Adds Context Beyond the Diff

A Qodo review runs in three steps:

1. Qodo’s Context Engine indexes the full codebase and the team’s PR history.
2. Specialized agents review bugs, architecture, cross-repository impact and, once Rule enforcement is on, the team’s rules.
3. A judge agent filters the results.

Findings similar to ones the team usually ignores are marked as lower relevance.

Qodo Works Alongside Gemini Code Assist

Teams already running Gemini Code Assist on GitHub can keep it and add Qodo as an independent second reviewer. In December 2025, Qodo named Gemini 2.5 Pro one of its default PR review models after testing it on its PR Benchmark (Qodo’s post).
