Gemini 3.8 Flash
Strong value for high-volume usage.
Overview
Gemini 3.8 Flash is Google's fast, budget tier in the Gemini lineup, built for everyday text, coding, agentic and multimodal work. Its one-million-token context window handles very long documents, though output is capped at 64k tokens and Google has released no technical documentation to back up its claimed performance. The launch pricing ($0.75 / $3.75 per million tokens) doubles by end of 2026, worth factoring into any cost projection. As a closed, proprietary model, there is no on-premise option: data runs through Google's cloud.
