OpenAI cut the price of GPT-5.6 Sol by 20%, surfaced on August 22 through the model's API documentation page rather than an announcement — no blog post, no benchmark chart, just new numbers on a pricing table. It was picked up on Hacker News, where it drew 90 points and 77 comments.
The headline figure is the percentage; the docs page is the only place the actual per-million rates live, and it's worth confirming whether input, cached-input and output tokens all moved together or only one line item did. Silent repricing via docs edit also means no migration note and no stated effective date beyond when the page changed — if you bill through Sol, reconcile against your own invoices rather than the percentage.
