  • Zero prompt retention. Zero prompt retention at the gateway by default; Google's own API data policies apply upstream. Details →

About Google

Google's Gemini family covers fast, inexpensive Flash and Flash-Lite tiers up to Pro-grade reasoning, with million-token context windows, native multimodality and image generation. Synthorai exposes Gemini through the OpenAI-compatible API you already use (no Google Cloud project or SDK setup required) with per-model live pricing below.

FAQ

How do I get a Google API key without a subscription?

You don't need a Google account: sign up on Synthorai, create one API key, and every Google model on this page works through the OpenAI-compatible endpoint: pay-as-you-go, no subscription (models marked "invited beta" additionally need an approved application).

What does the Google API cost?

Token-billed models start at $0.1/M input tokens; every model's live per-unit price is in the table above. These are provider list prices with no platform markup.

Can I use my own Google key (BYOK)?

Gemini BYOK isn't available yet; requests run on Synthorai's managed channels at the listed pay-as-you-go rates.

What is Google's data-retention policy via API?

Zero prompt retention at the gateway by default; Google's own API data policies apply upstream.
