Market position
On blended price ($7.60 per 1M tokens at 30% input, 70% output) it is cheaper than 13% of models in the Mid-range price tier: 92nd cheapest of 113, tied with 7 others. Across every price tier it is cheaper than 15% of priced text models in the catalogue: 252nd cheapest of 303, tied with 7 others. No Arena score has been published for GPT-6 Sol Pro, so this page does not rank it on quality and OptimNow's quality bars do not apply to it. 66 of the 113 models we list in the Mid-range price tier carry one. An unranked model is unmeasured, not poor: the benchmark needs votes, and a recent release has not had time to collect them.
Licence, size and capabilities
GPT-6 Sol Pro is recorded here as proprietary: access is through an API, priced by the token. Its parameter count is not published. Listed capabilities: Text, Vision, Reasoning, Agents. Filling its 1M context window once costs $2.00 in input tokens at list price.
Pricing by host
A host is a company that runs the model and sells it by the token: the model maker, a cloud platform like Amazon Bedrock, Azure or Vertex, or an independent host. One model, several hosts, and often several prices. This model is sold by 2 different hosts. The price we quote elsewhere on this page is marked. We quote one host's rate so that models stay comparable; it is not a recommendation to buy there.
The price we quote is already the cheapest of the 2 hosts: OpenAI at $2.00 input / $10.00 output per 1M tokens. All of them charge within 10% of one another.
| Host | Input $/1M | Output $/1M |
|---|---|---|
| OpenAI (model maker, price we quote) | $2.00 | $10.00 |
| Azure (price we quote) | $2.00 | $10.00 |

Monthly cost at 100K requests, by business use case
From the after-discounts figure (prompt caching on the cached input share, batch API for async workloads, only where OpenAI publishes those rates), which assumes you implement both, to the list price. One figure means no discount is published.

It publishes a batch rate, and that discount is conditional: when the batch discount applies.
These are list prices. Your real cost also depends on caching and batching, negotiated discounts, marketplace agreements, and the contracts you already have. OptimNow audits exactly that.
