Gemini 4 Argon ranks in top 5 on Arena's Agent Arena and overall leaderboards

Arena says Gemini 4 Argon (High), a Google DeepMind model, ranks in the top 5 on its Agent Arena leaderboard, and congratulates Google DeepMind in an October 13, 2026 post on X. The post does not give the model's exact position, its scores, or the tasks Agent Arena measures.

A second X post from Testing Catalog says Gemini 4 Argon placed fifth on Arena's overall ranking, behind Opus 5.5, GPT 6.1 Sol, Fable 5.1, and GPT 6 Astra. That post is a secondary report of the overall ranking and cites no scores of its own.
