Google Gemini 4 Argon benchmark results land closer to the frontier than recent Google models

Google's Gemini 4 Argon is closer to the AI frontier than any Google model in months

Google DeepMind's Gemini 4 Argon scores 165 on Epoch AI's composite capability index ECI, close to GPT-6 Astra at 166 and Opus 5.5 at 167.

Why it matters: Argon's scores differ sharply between the two test setups, and vendor API features such as retained reasoning and context compression were part of the benchmark comparison.
