Google AI Studio

Google AI Studio is the primary entry point for developers who want to work with Google's Gemini family of AI models. It's a free, no-download-required browser environment that makes Gemini's capabilities immediately accessible without cloud billing setup.

## What You Can Do in Google AI Studio

**Prompt Design** — three modes for building prompts: - **Freeform** — single-turn conversations and instructions - **Structured** — multi-turn chat format with system instructions - **Function Calling** — define tools your model can call, test structured output

**Multimodal Inputs** — Gemini's strength is processing multiple modalities in a single prompt: - Upload images and ask questions about them - Submit video files for analysis and summarization - Process audio recordings for transcription and analysis - Combine text + image + code in a single query

**Model Selection** — switch between Gemini models in the same interface: - Gemini 2.5 Pro (most capable, 1M token context) - Gemini 2.5 Flash (fast, efficient) - Gemini 1.5 Flash (high-speed, cost-effective) - Experimental models before general release

**Get Code** — every prompt you build exports as working code in Python, JavaScript, Swift, Dart, Android, or REST — so moving from experimentation to production is a copy-paste operation.

## Key Developer Features

**API Key Management** — generate Gemini API keys directly in AI Studio. Free tier includes generous usage; pay-as-you-go billing activates when needed.

**System Instructions** — define how the model should behave in your application. Test system prompt effects interactively before hardcoding them.

**Context Caching** — configure caching for large context windows (up to 1M tokens) to reduce API costs on repeated large-context requests.

**Token Counting** — real-time token counter shows exactly how many tokens your prompt consumes, essential for managing API costs.

## Who Uses Google AI Studio

- Developers building Gemini-powered applications - Researchers testing multimodal AI capabilities - Prompt engineers optimizing instructions - Students and educators exploring AI capabilities - Product teams prototyping AI features before committing to infrastructure

## Relationship to Vertex AI

Google AI Studio is the developer-facing playground; Vertex AI is the enterprise production platform. Most developers start in AI Studio, then migrate workloads to Vertex AI for production when they need enterprise features (VPC, SLAs, compliance).

## Pricing

Google AI Studio itself is free. Gemini API access includes a free tier (RPM and TPD limits vary by model); beyond free limits, requests are billed at standard Gemini API pricing.
