Gemini 4 Argon on Gemini Enterprise Agent Platform

Summary

Google Cloud's model page for Gemini 4 Argon on the Gemini Enterprise Agent Platform (formerly Vertex AI) lists the model as GA, released on 2026-10-13, the same day as its public launch on the Gemini API. It gives the regions and a retirement floor.

Key points

• Launch stage: GA; release date 2026-10-13; model ID gemini-4-argon.
• Locations: global, the us and eu multi-regions, europe-west2, and asia-southeast1.
• Retirement on the platform: "October 13, 2027 or later". The model may stay available on the Gemini API after that.
• Computer use is listed as supported; the Cyber Permissive variant (gemini-4-argon-cyber-permissive) does not support it.

Why it matters

Argon is GA on both of Google's APIs, so enterprise users with EU data residency needs can use it in the eu multi-region or europe-west2.
