AI Gateway adds no markup on token pricing, so these changes reach you at the upstream rate.

The changes apply to both short and long context pricing.

GPT-5.6 Sol keeps the same price; its fast mode now runs 2.5x faster, up from 1.5x. Model IDs are unchanged, so existing requests get the new rates and speed with no code change.
