Developer access and Gemini 3 Flash pricing
Gemini 3 Flash is available in preview for developers through the Gemini API. Access options include Google AI Studio, Google Antigravity, Vertex AI, and the Gemini Enterprise environment. Developers can also use the model through tools such as Gemini CLI and Android Studio integrations.
Google's Gemini API pricing documentation lists Gemini 3 Flash at $0.50 per million input tokens and $3.00 per million output tokens. For comparison, Gemini 2.5 Flash is listed at $0.30 per million input tokens and $2.50 per million output tokens.
Google reports that Gemini 3 Flash uses about 30% fewer tokens than Gemini 2.5 Pro for typical tasks.

These performance figures are drawn from Google's materials and referenced third-party measurements.
Background on the Gemini 3 model family
