About

Google AI Studio is Google's browser-based development environment for building, testing, and deploying applications powered by Gemini AI models. It provides a visual playground for experimenting with prompts, fine-tuning models on custom data, and generating API keys for production use — all without installing anything locally. The platform offers access to the full Gemini model family, including Gemini 3.1 Pro Preview (the most capable), Gemini 3.1 Flash-Lite (fastest), and legacy 2.5 models. A generous free tier gives developers access to all models with free input and output tokens for experimentation and prototyping, making it one of the most accessible ways to start building with frontier AI models. Google AI Studio 2.0 pushed the platform significantly forward in early 2026 by adding full web app prototyping capabilities with built-in Firebase integration, secrets management, and collaborative scaffolding. Developers can now go from prompt to deployed prototype without leaving the browser. The platform also supports multimodal inputs — text, images, audio, video, and code — across all Gemini models. Paid tier pricing is competitive: Gemini 3.1 Flash-Lite starts at just $0.25 per million input tokens, while the flagship Gemini 3.1 Pro Preview is $2.00 per million input tokens (with 50% batch discounts available). Additional features include context caching for repeat queries, Google Search grounding for fact-checked responses, Imagen 4 image generation ($0.02-$0.06 per image), and Veo 3 video generation ($0.15-$0.40 per second). For developers already in the Google ecosystem, AI Studio integrates directly with Firebase, Google Cloud, Google Workspace, and Vertex AI for enterprise deployment. The API follows the same interface as Vertex AI, making it easy to move from prototype to production.
