Input drops 20%, output drops a third.\n\nThe discount applies on every OpenAI service tier:\n\nService tier | You pay now (input / output) | New list price (input / output) | You paid before (input / output) |\n|---|---|---|---|\nDefault | $2.00 / $10.00 | $4.00 / $20.00 | $2.50 / $15.00 |\nFlex | $1.00 / $5.00 | $2.00 / $10.00 | $1.25 / $7.50 |\nPriority (fast mode) | $4.00 / $20.00 | $8.00 / $40.00 | $5.00 / $30.00 |\n\nRates are per million tokens for requests up to 272K tokens. Cached tokens, cache writes, long-context requests above 272K, and the US regional rates all move by the same proportion. See the [pricing page](https://vercel.com/docs/ai-gateway/pricing) for all model rates.\n\nThe model ID is unchanged, so requests you already send bill at the new price automatically. [BYOK](https://vercel.com/docs/ai-gateway/authentication-and-byok/byok) requests bill at your own rate with OpenAI.\n\nTo use Sol in a coding agent, run `vercel ai-gateway coding-agents setup`\n\nto connect your agents to AI Gateway, then select `openai/gpt-5.6-sol`\n\nin the agent's model settings.
