Gemini 4 Argon begins rolling out to paying users; lower-tier subscriptions cannot access it fully

Google's Gemini 4 Argon is now being rolled out broadly, currently limited to paying users, with lower-tier subscriptions unable to access it fully. Model capabilities remain unchanged. Google cites previous benchmarks stating it leads in reasoning and agent coding. The model has been trained to refuse malicious instructions and features an automated monitoring mechanism that halts processing when anomalous workflows are detected.
