Gemini 3.1 Flash

Validating · Emerged 2026-03-03 · 48 days old

Gemini 3.1 Flash is Google's mid-2026 speed-tier refresh of the Gemini model family — a family-of-variants brand rather than a single model. Developers use "3.1 Flash" as the umbrella query; Google ships it as specialized siblings: Flash-Lite (text/multimodal), Flash Live (audio), Flash TTS (speech synthesis), and Flash Image (a.k.a. Nano Banana 2).

The tier opened on March 3, 2026 with Flash-Lite at \$0.25/\$1.50 per million input/output tokens — 1/8 the cost of Gemini 3 Pro. Flash Live shipped March 26 for real-time audio; Flash TTS shipped April 15 with prompt-steerable "audio tags" that control pace, accent, and scene inline.

Think of it as Google's Swiss Army knife — the handle is "3.1 Flash," each blade (Lite, Live, TTS, Image) is tuned for a different cut.

TL;DR

Google opened the Gemini 3.1 Flash tier with Flash-Lite on March 3 at 1/8 Pro pricing, then shipped Flash Live (audio, March 26) and Flash TTS (April 15) in rapid succession. GTrends related queries are dominated by pricing and API long-tails — developers are evaluating it as a default cheap tier, not just reading launch posts.
