Google Closes Pricing Triangle with Gemini 4 Argon Launch

Google's Gemini 4 Argon has entered the market at $2 per million input tokens and $10 per million output tokens, matching OpenAI's GPT-6.1 Sol pricing exactly. This marks a convergence in business models among major US frontier labs.

The benchmark score that matters is DeepSWE v1.1, where Argon leads with 77.9%, edging out Claude Opus 5.5 at 74.2% and GPT-6 Astra at 74.1%. However, these figures are vendor-reported and lack independent verification.

Google's entry with Argon is distinct from others in that it claims benchmark leadership while matching OpenAI's pricing exactly on day one. The question remains whether this convergence reflects a shared bet on volume-and-platform economics or simply the recognition of an untenable higher price point in a market where open-weight models from Chinese labs dominate.
