Gemini 4 Argon vs GPT-6.1 Sol
Gemini 4 Argon is billed by Google. GPT-6.1 Sol is billed by OpenAI. A pair is two models from different providers whose higher published input rate is at most 1.5 times the lower one, and whose higher published output rate is at most 1.5 times the lower one. Closer rates are listed first. Each model is in at most 2 pairs, and the list stops at 12. The figures below are the rates stored on those two rows, the differences between them, and the cost of one sample workload. This page does not score quality.

Sample workload
The sample is the calculator's starting workload: 2,000 input tokens and 800 output tokens per request, 1,000 requests a day. A month in the calculator is 30 days, so that is 30,000 requests. The cost uses the stored input and output rates only. Cache hits, batch discounts, long-context surcharges, peak hours, and prices scheduled after an introductory window are not included. The rate label and the notes below name those other published rates.
Gemini 4 Argon is $0.012 per request and $360.00 per month ($120.00 input and $240.00 output over the month). GPT-6.1 Sol is $0.012 per request and $360.00 per month ($120.00 input and $240.00 output over the month).
On this sample the two stored rates cost the same amount.

Notes from the sources
Gemini 4 Argon
Paid standard, introductory
Paid standard introductory rate in effect through 30 November 2026. From 1 December 2026 the pricing page lists $4 input, $0.20 cached input, and $20 output. Output price includes thinking tokens. Not available on the free tier. Implicit caching only. The context window is a unified 1,048,576-token budget shared by input, thinking, and output. The default synchronous output cap is 65,536 tokens; long decode can use the rest of the window, so max output is recorded as 1,048,576.
GPT-6.1 Sol
Standard, under 272K
Short-context standard rate for prompts under 272K tokens. The same pricing table lists long-context rates of $4 input, $0.20 cached input, and $15 output per 1M tokens. Batch and Flex are half of standard. Context window 1.05M and max output 128K are from the OpenAI API model list.
