Vercel AI Gateway、GPT-5.6 Sol のリスト価格引き下げと割引継続を報告

OpenAI just lowered list pricing for GPT-5.6 Sol. The 50% AI Gateway discount continues and applies to the new list price now through September 18th.

Pricing

The 50% discount applies on every tier on the OpenAI provider, against the new list price.

Service tier

You pay now (input / output)

New list price (input / output)

You paid before (input / output)

Default

$2.00 / $10.00

$4.00 / $20.00

$2.50 / $15.00

Flex

$1.00 / $5.00

$2.00 / $10.00

$1.25 / $7.50

Priority (fast mode)

$4.00 / $20.00

$8.00 / $40.00

$5.00 / $30.00

Rates are per million tokens, for requests up to 272K tokens. The reduction is the same proportion on every tier: input is 20% lower than before and output is a third lower. Cached tokens, cache writes, and long-context requests above 272K move on the same terms, as do the US regional rates. Current rates for every model are on the pricing page.

The discount itself has not changed, and neither has the date it ends. This is the same 50% off applied to a lower list price. Billing through AI Gateway picks this up automatically. BYOK requests run on your own account and bill at your rate with the provider.

The model ID (openai/gpt-5.6-sol) is unchanged, so requests you already send bill at the new rate with no code change:

Sol takes a reasoning effort up to max for the hardest problems, accepts text, image, and PDF input, and carries a long context window.

To use it in a coding agent, see the coding agents guide, then run vercel ai-gateway coding-agents setup to connect agents like Claude Code, Codex, OpenCode, Cursor, Pi, and more, and select openai/gpt-5.6-sol inside the agent.
