Gemini 4 Argon: Google Is Back at the Frontier

Google released Gemini 4 Argon on September 30. On its own numbers, Argon beats GPT-6 Astra and Claude on 13 of 19 benchmarks. Launch pricing is $2/$10 per million tokens, rising to $4/$20 later.

It leads on knowledge work: #1 on the Vals Index (68.9%), plus finance (65.4%) and legal (19.6%, about 3x the field). Its weak spot is terminal coding, where Opus 5.5 leads at 66.4% vs 57.4%.

Most scores are vendor-reported, and access is limited to vetted cyber defenders for now.
