5 things to try with Gemini 3 Pro in Gemini CLI

Source: Google Developers Blog

Gemini 3 Pro is now available in Gemini CLI. The most intelligent model is integrated directly into the CLI, delivering state‑of‑the‑art reasoning for better commands, enhanced support for complex engineering through agentic coding, and smarter, more tailored workflows via advanced tool use.

We are rolling out access gradually to keep the experience fast and reliable.

• Gemini 3 Pro is available now in Gemini CLI for Google AI Ultra subscribers (Google AI Ultra for Business access is on the roadmap) and for those who have access via a paid Gemini API key.
• For Gemini Code Assist Enterprise users, access is coming soon.
• All other users, including Google AI Pro, Gemini Code Assist Standard, and free‑tier users, can join the waitlist here to get access as it becomes available.

You can also track our rollout progress by following this GitHub discussion.

Start using Gemini 3 Pro with Gemini CLI

If you’re a Google AI Ultra subscriber or have a paid Gemini API key, get started immediately by upgrading your Gemini CLI version to 0.16.x:

npm install -g @google/gemini-cli@latest

After confirming your version, run /settings and toggle Preview features to true. Gemini CLI will now default to Gemini 3 Pro.

5 practical ways to tap into Gemini 3 Pro in Gemini CLI

Build anything in the terminal with improved agentic coding

Gemini 3 Pro excels at coding because it can synthesize disparate pieces of information—text, images, and code—and follow complex, creative instructions. It understands the intent behind your idea, allowing you to go from a rough concept to a functional starting point in a single step.

Generate a ready‑to‑deploy app with 3D graphics

Gemini 3 Pro’s agentic coding capability lets you provide a creative brief and a technical spec together. It can create a detailed execution plan and generate the entire scaffold for a runnable web project.

Objective: Build a visually stunning, photorealistic 3D Voxel simulation of the Golden Gate Bridge using Three.js, prioritizing quality and complex visuals (no simple blocks), atmospheric depth and 60FPS performance.

Visuals & Atmosphere:
- Lighting: Slider (0‑24h) controlling sun position, light intensity, sky color, and fog color.
- Fog: Volumetric‑style fog using sprite particles that drift and bob. Slider 0‑100. 0 = True Zero (Crystal Clear). 100 = Dense but realistic (not whiteout).
- Water: Custom GLSL shader with waves, specular reflections, and manual distance‑based fog blending (exp2) for seamless horizon integration.
- Post‑Processing: ACESFilmic Tone Mapping and UnrealBloom (optimized for glowing lights at night).

Scene Details:
- Bridge: Art Deco towers with concrete piers (anchored to seabed), main span catenary cables, and suspenders.
- Terrain: Low‑poly Marin Headlands and SF Peninsula.
- Skyline: Procedural city blocks on the SF side.
- Traffic: Up to 400 cars using `InstancedMesh`, positioned accurately on top of the deck (ensure vertical alignment prevents clipping into the concrete). Each car features emissive headlights (white) and taillights (red).
- Ships: Procedural cargo ships with hull, containers, and functional navigation lights (Port/Starboard/Mast/Cabin) moving along the water.
- Nature: Animated flocking birds.
- Night Mode: At night, activate city lights, car headlights, ship navigation lights, tower beacons, street lights.

Tech & Controls:
- Core: Must output only single HTML file `golden_gate_bridge.html` to be run in a blank Chrome tab. Import Three.js/Addons via CDN map.
  - `three` (Core library) via CDN (ES Modules).
  - `three/examples/jsm/...` modules via Import Map.
  - No build step (Vite/Webpack). Pure HTML/JS.
- UI: Visually appealing sliders for Time (0‑24h), Fog Density (0‑100%), Traffic Density (0‑100%), and Camera Zoom.
- Optimization: `InstancedMesh` for all repetitive elements (cars, lights, birds).

Turn a visual idea into a working app

You can drag and drop an image of a UI sketch into your terminal. Gemini 3 Pro’s multimodal understanding will analyze the drawing, identify UI elements, and generate the corresponding HTML, CSS, and JavaScript.

Create a UI for "Project Constellation," an internal brand intelligence tool prototype that shows a customer acquisition pipeline. The aesthetic is an ultra‑creative, futuristic dark‑mode nebula. Luminous, iridescent threads representing customer journeys weave through semi‑transparent glass pillars. A sleek, floating data card with Tailwind CSS precision materializes when hovering over a pillar. I've prepared a sketch for you to work from: @sketch.png.

Improve your daily work

Small improvements in everyday workflows—refactoring code, debugging errors, managing infrastructure—create real productivity gains. Gemini 3 Pro’s state‑of‑the‑art reasoning follows the nuances of complex, multi‑part commands with greater precision, making routine engineering tasks faster and more reliable.

Generate complex shell commands with natural language

With Gemini CLI, describe what you want in plain English and let Gemini 3 Pro translate it into the appropriate shell command(s). It can also parse dense formatted output back into natural language.
