What shipped? Vercel AI Gateway is offering GPT-5.6 Sol at 50% off for one month.
What changed? From August 17 through September 18, every request to GPT-5.6 Sol routed through Vercel AI Gateway gets a 50% discount. No signup, no coupon — the price drops automatically on all Gateway traffic to the model.
Why does a builder care? If you're already using OpenAI's GPT-5.6 Sol (or considering it), routing through AI Gateway is now the cheapest way to run it. You also get automatic fallbacks, spend tracking, request traces, and the rest of the Gateway toolset — at half price through mid-September.
