Gemini 3.8 Flash-Lite

CLOSED

Google · Gemini 3.8 family · released Sep 16, 2026

Google's September 16, 2026 high-volume tier — the 3.8 generation's Flash-Lite, at $0.25/$1.50 per Mtok (a third of 3.8 Flash's rate). Keeps the full text/vision/audio/video modality stack, which is the Lite line's real differentiator against Qwen Flash-Next and Claude Haiku 5, both of which arrived the same week. The launch table stays narrow (Google saves its multi-suite treatment for Pro/Flash): four headline rows plus OSWorld-Verified and Video-MME Pro, a benchmark revision Google is now co-citing with ByteDance. Filed as its own row rather than an effort config because Google bills Lite as a distinct model id.
