Could Gemini 4 Argon replace Opus 5.5, Sonnet 5.5, GPT-6 Astra, or GPT-6.1 Sol? Access is still restricted. Argon leads Google's DeepSWE comparison, but trails Opus and Astra on FrontierSWE. I'd evaluate specific tasks before changing a default.

Vals' Mini-SWE-agent terminal runs put Argon behind Opus, Sonnet, and Astra. It scores above Sol 6.1, but costs about 10x as much per test at the published API rates. Some Claude tasks used fallbacks. That doesn't establish value under my subscriptions.

I leave room for another provider or tool to earn a role. Argon leads the broader Vals Index; task mix matters. I'd compare accepted results, review time, failures, and cost on my own work. Terminal comparison: https://www.vals.ai/benchmarks/terminal-bench-4
