Frequently asked questions
Is API Gemini free?
Google offers a developer free tier for selected Gemini models and usage levels. Available models, quotas, data-use terms, and regional access differ, while higher-volume or Vertex AI usage is billed.
Is Gemini cheaper than Chatgpt?
The services are billed differently: Gemini API pricing varies by model and token usage, while ChatGPT subscriptions cover the consumer application rather than OpenAI API usage. Compare the exact APIs and workload instead of subscription prices.
How to use Gemini AI API for free?
Create a project in Google AI Studio, generate an API key, and use a model covered by the current free tier while staying within its quotas and terms. Move the key to a server-side secret before deploying an application.
