Gemini 4 Argon, Claude Sonnet 5.5, GPT-6.1 Sol pricing tie until Dec 1 · 1 source tracked

By PulseAugur Editorial · [1 sources] ·

Google has released its Gemini 4 Argon model, which is priced identically to Anthropic's Claude Sonnet 5.5 and OpenAI's GPT-6.1 Sol until December 1, 2026. All three models currently cost $2 per 1 million input tokens and $10 per 1 million output tokens. However, Google plans to double the price of Gemini 4 Argon on December 1, making it significantly more expensive than the other two models for standard workloads. GPT-6.1 Sol has a split pricing tier that increases costs for prompts exceeding 272K input tokens, while Claude Sonnet 5.5 and Gemini 4 Argon maintain a single rate across their context windows. AI
