GPT-6.1 Sol pricing, benchmarks and cost analysis

GPT-6.1 Sol costs $2,244 a month for the default workload of 2,000 input and 500 output tokens, 10,000 requests a day with 40% cached input. That is 155% above the median model ($881). It ranks #70 of 102 on cost, where #1 is the cheapest.

It scores 168.4 on the Epoch Capabilities Index (#3 of 66). Among the 4 other models within 2 points, none costs less, and it costs 71% less than their median ($7,824). No other stable-priced model with an ECI at least this high costs less for the same workload.

It generates 49 tokens per second, 42% slower than the median model (84), #28 of 28. Cached input is 95% cheaper than fresh input, a bigger discount than the 90% median. It is a proprietary model served by OpenAI. The batch API cuts the default workload to $1,122 a month.
