Gemini Code Assist offers IDE code completion and generation, project-aware chat, and smart actions; its Preview agent mode can also carry out multi-step tasks using tools. Which features are available depends on your IDE and subscription. As of June 18, 2026, Google says its IDE extensions and Gemini CLI no longer serve requests for Gemini Code Assist for individuals or Google AI Pro and Ultra; affected users are directed to Antigravity and Antigravity CLI. The Standard and Enterprise offerings for organizations are separate.

What tools does Gemini Code Assist offer?

For organizational Standard and Enterprise users, Gemini Code Assist brings several kinds of coding help into supported IDEs. The core distinction is between suggestions and chat, which help you produce or understand code, and agent mode, which can use tools to work through a multi-step task.

  • Code completion and generation: Get code suggestions while working and generate or transform code from instructions.
  • IDE chat: Ask for coding guidance, generate code, and use project context. Standard and Enterprise documentation also describes context management and custom commands or rules.
  • Smart actions: Invoke assistance for common coding tasks from within the IDE.
  • Agent mode: Ask questions or delegate a task that can involve multiple steps, IDE context, and available tools. It is a Preview feature subject to Pre-GA terms, not a generally available replacement for ordinary completion or chat.
  • Code customization: Enterprise can retrieve context from indexed organizational repositories to make suggestions more relevant to private APIs, internal libraries, and coding conventions.

These capabilities are documented across Google’s Gemini Code Assist overview and IDE feature documentation. Availability can differ by IDE and feature.

Which IDEs and environments are supported?

Google lists Cloud Shell Editor, Cloud Workstations, and Android Studio as environments where Gemini Code Assist is available by default. Extensions are listed for Visual Studio Code and these JetBrains IDEs: CLion, DataGrip, GoLand, IntelliJ IDEA Community, Educational, and Ultimate editions, PhpStorm, PyCharm Community and Professional, Rider, RubyMine, and WebStorm.

Elebase USB to USB C Adapter for iPhone 18 Pro Max,USBC Car Charger Adapter
  • Read Before You Buy — No Video Output: These adapters support charging and USB 2.0 data transfer, but cannot transmit video signals. Except for standard USB webcams (which use USB data only), they are not compatible with HDMI/DisplayPort cables, video-capable USB-C hubs, or docking stations with video output.
  • Convert USB-A Ports to USB-C: Designed to connect USB-C earphones, cables, flash drives, card readers, and other USB-C accessories to standard USB-A ports. Plug-and-play with no drivers or software required.
  • Aluminum Alloy Housing: Built with a sturdy aluminum alloy shell that aids in heat dissipation and protects against daily wear and scratches. Designed to maintain a stable and secure connection.
  • Compact & Travel-Friendly: The ultra-compact design allows the adapter to stay plugged into your device without blocking adjacent ports or adding bulk, reducing wear and tear on your original USB ports.
  • 12-Month Warranty: Backed by a 12-month manufacturer warranty for peace of mind. Designed to meet strict quality control standards for reliable everyday performance.

That list is not a promise that every capability works in every environment. Google’s agent-mode documentation specifically names VS Code and IntelliJ, while code customization has its own IDE and plugin requirements. Check the relevant feature page and current plugin versions before choosing a workflow. See Google’s IDE compatibility documentation and agent mode overview.

What can agent mode do, and how should you control it?

Agent mode can use IDE context and tools to handle work such as generating code from design documents, issues, or TODOs. You can review or edit its plans and tool use, and configure MCP servers. The precise built-in tools differ: Google’s documentation describes Gemini CLI built-in tools in VS Code and tools such as file reading and writing, grep, symbol resolution, and Git in IntelliJ.

When the agent requests a tool, the IDE checks whether the action is allowed. Filesystem changes and other mutating operations normally require approval unless you have configured automatic permission. Review proposed actions and scope permissions deliberately rather than treating the agent as an unattended automation system. Google warns: “There isn’t an option to undo changes made to resources outside your IDE in agent mode, so be careful where you use it.” The usage page was updated September 24, 2026; consult Google’s agent mode overview and agent mode usage guide for current behavior.

Which languages does it support?

Google describes two different language scopes: languages supported for general assistance and prompts, and the narrower set indexed for Enterprise code customization. They should not be treated as the same list.

General assistance

Google lists prompts in Arabic, Bengali, Bulgarian, Chinese (simplified and traditional), Croatian, Czech, Danish, Dutch, English, Estonian, Finnish, French, German, Greek, Hebrew, Hindi, Hungarian, Indonesian, Italian, Japanese, Korean, Latvian, Lithuanian, Norwegian, Polish, Portuguese, Romanian, Russian, Serbian, Slovak, Slovenian, Spanish, Swahili, Swedish, Thai, Turkish, Ukrainian, and Vietnamese. PHP, Python, R, Ruby, Rust, Scala, SQL, Swift, TypeScript, and YAML are identified as verified coding languages; Google notes that assistance extends more broadly. See the supported languages page.

Enterprise code customization indexing

For repository indexing, Google separately lists C, C++, C#, Go, Java, JavaScript, Kotlin, PHP, Python, Rust, TypeScript, Verilog, and SystemVerilog, as well as Markdown documentation. It says this feature does not index media or use other coding languages. See Google’s code customization overview.

What does Enterprise code customization require and limit?

Code customization is Enterprise-only. It retrieves context from indexed private repositories; it is not simply a switch that makes every private project available instantly. Google documents a 24-hour reindexing interval, one repository index per project and organization, a maximum of 20,000 repositories per index, 500 repository groups per index, and 500 repositories per group (Google Cloud documentation, 2026).

On data handling, Google states, “The Gemini model doesn’t train on your private source code.” It also says code is stored in a dedicated single-tenant environment, employee administrative access is restricted absent justification and optionally explicit approval, and results are private to the customer. These are Google’s statements about its service, not an independent audit conclusion.

How do organizations set up Standard or Enterprise access?

Google’s organizational setup involves subscription and license administration as well as configuration in Google Cloud and each user’s IDE. The setup page directs prospective purchasers to Google Cloud sales. The documented sequence is:

  1. Purchase a Gemini Code Assist Standard or Enterprise subscription and assign user licenses.
  2. Enable the Gemini for Google Cloud API for the relevant project.
  3. Grant the required IAM roles to users.
  4. Have each user install the appropriate IDE plugin, sign in, and select a Google Cloud project.

Follow Google’s current setup instructions for the required roles and exact configuration. This organizational path is distinct from consumer-tier access, which stopped serving requests through the Gemini Code Assist IDE extensions and CLI on June 18, 2026.

How should you choose a workflow?

For everyday in-editor suggestions or questions, start with completion, smart actions, and chat in an IDE that supports the needed feature. Consider agent mode when a task genuinely benefits from multiple tool-assisted steps and you can review its plan and actions. An organization considering code customization should first confirm Enterprise eligibility, repository-provider support, language coverage, region, IDE versions, and indexing limits.

Also note a separate older change: Google’s deprecation page says the prior Gemini Code Assist tools invoked through the @ operator stopped working after October 14, 2025, and that agent mode replaced them. This is distinct from the June 2026 end of consumer-tier IDE extension and CLI requests. Check Google’s deprecations page for current product status.
