One base URL and key work with virtually any app, SDK or self-hosted chat client that supports a custom API address.
Route requests to OpenAI models, Claude, Stability diffusion, Azure TTS and vector database services from a single account.
Consumption is metered in points with a published multiplier, so you pay for what you use rather than a flat subscription.
Identical request bodies return cached answers for free for 24 hours, and a header can disable caching when freshness matters.

Google's rapid prototyping IDE and developer API workbench for building multimodal applications with Gemini models.
Allows developers to drop hours of video, multi-track audio files, high-resolution images, entire codebases, and multi-hundred-page PDFs directly into the prompt window with up to 1,000,000 tokens of shared context.
Provides direct access to Google's frontier reasoning and agentic models with granular controls over thinking tokens, temperature, function declarations, and strict JSON schema output validation.
Includes a dedicated `/live` studio interface for testing sub-second, bidirectional voice and screen/camera interactions powered by `gemini-3.8-live`, `gemini-3.8-live-extended-thinking`, and `gemini-3.5-live-translate-preview`.
Connects model responses to live Google Search results and Google Maps geospatial data with a single toggle, including 5,000 free grounded requests per month on Paid tiers before $14/1,000-query metering.
