GPT-5.6 Sol is the flagship of OpenAI’s GPT-5.6 series, scoring 59 on the Artificial
\nAnalysis Intelligence Index. Headline pricing matches GPT-5.5 at $5 in \/ $30 out per million
\ntokens with a ~1.05M-token context, available through the OpenAI API and Microsoft Azure
\nAI.<\/p>\n
The long-context billing is the thing to read carefully. Requests above 272K input tokens
\nare charged at 2\u00d7 the input rate and 1.5\u00d7 the output rate \u2014 effectively $10 \/ $45 \u2014 so
\nlong-context work costs materially more than the advertised price suggests. A single feature
\nthat routinely pastes in large documents can therefore run at nearly double the modelled
\ncost, and because the threshold is crossed per request rather than per account, the overage
\nis invisible until it appears on the invoice. Instrument prompt sizes before you scale, and
\nconsider whether a model with flat pricing across its whole window is cheaper in practice for
\nyour specific mix. At 59 on the intelligence index Sol is genuinely near the top of the
\nfield; the question is whether your workload sits above or below that 272K line.<\/p>","protected":false},"excerpt":{"rendered":"
