About

Google's AI Studio is the fastest way to call Gemini models from your agent for free. You get a free API key tied to your Google account with a generous daily quota, and the API speaks the same format as OpenAI's, so most agent frameworks work by swapping the base URL. It handles text, vision, and audio, making it the flagship free brain for AI agents.
