🚨 Gemini 3.8 Flash just appeared on Arena again

Looks like Google is testing a fresh checkpoint under that name.

My bet: either Gemini 3.9 Flash or an early Gemini 4.0 Pro checkpoint.

Screenshot of a notification from the alex getman app: a new gemini-3.8-flash checkpoint in Google Arena, differing in output (Web instead of Text, Web), observed today at 6:23 AM.
