GPT-5.6 Sol API pricing drops 20% on input, 33% on output
↗
GPT-5.6 Sol, the frontier model in the GPT-5.6 family, now costs $4 per million input tokens and $20 per million output tokens, a 20% input and 33% output price cut.
For engineers building on the GPT-5.6 API, the price cut directly lowers the cost of high-reasoning workloads. The 20% input and 33% output reduction makes the frontier model more affordable, but the promotional pricing is only guaranteed through November 21, 2026, so budgets should account for a possible increase later.
