Google Gemini 4 Argon closes the gap with OpenAI and Anthropic but doesn't take a clear lead

Gemini 4 Argon is Google's first frontier model in over seven months. It matches GPT-6 Astra in independent testing but can't keep up with Anthropic's Claude Opus 5.5. The per-token price is low, but Argon burns through more than twice as many tokens per task as Astra.
