BusyNomad · reddit · 2026-10-14

A Reddit user posted a screenshot of the Gemini web app showing an unreleased "Gemini 4 Argon" model, marked "New" and described as "Complex tasks," listed alongside 3.5 Flash-Lite, 3.8 Flash, and 3.1 Pro in the Pro user model picker. This suggests Google may be quietly A/B testing its next flagship model; not yet officially announced, so treat as unverified.
