Our take
Written Sep 30, 2026GPT-6.1 Sol is a hosted-only model: we list no download for it, so using it means choosing a host. Nothing here measures its quality, so the decision rests on which offer you pick and on how much text a single request can carry.
Reach for it when your work arrives as long documents or file bundles that would otherwise have to be split up before you can ask a question, and when you can judge the answer yourself. Several companies serve it, and the listed rates differ sharply between offers, so compare them before you commit. Skip it if you need measured evidence of coding, reasoning or chat quality, or if you need to run the model on your own hardware.
The case for it
- A single request carries a very large amount of material, so long documents need not be split up first — that saves the chunking and reassembly work a smaller capacity forces on you.
- Text, images and files go into the same request, so a document or a screenshot does not have to be transcribed into the prompt by hand.
- The cheapest listed offer sits well below the dearest for the same model, so which offer you pick matters more than the model choice itself.
The case against it
- No benchmark score of any kind is supplied, so quality has to be established by a trial on work you can check yourself.
- Listed rates differ sharply between offers, so the bill depends on the row you choose rather than on the model.
- No licence is supplied, so we cannot tell you what commercial use or redistribution is permitted.
How good is it?
We hold no score for this model.
So there is no figure here for everyday use, coding, agent work or writing. That is a gap in our data, not a low score.

Why this differs from the header. The strip above quotes OpenAI's own list price; this is the cheapest live offer, whoever is serving it — a reseller undercutting a lab is ordinary commerce, not an error.
