Google AI Studio

Google AI Studio is Google’s free browser playground for building with Gemini. Test prompts against Gemini models, generate a free Gemini API key, and build apps, with no credit card needed for the free tier. The free tier covers selected text, audio, and live models, while image models and advanced features need a billed project. Free-tier prompts and outputs may be used to improve Google’s products, so do not send private or customer data through it.
