## AI overview

OpenAI lowered the list price of GPT-5.6 Sol, while a 50% AI Gateway discount applies to the lower price through September 18. Input pricing falls by 20% and output pricing by one third across service tiers. Existing requests receive the new price automatically because the model ID is unchanged, and Sol can be configured for coding agents through AI Gateway.

## Source excerpt

OpenAI lowered list pricing for GPT-5.6 Sol, and the 50% AI Gateway discount now applies to the new, lower price through September 18. Input drops 20%, output drops a third. The discount applies on every OpenAI service tier: 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. Cached tokens, cache writes, long-context requests above 272K, and the US regional rates all move by the same proportion. See the pricing page for all model rates. The model ID is unchanged, so requests you already send bill at the new price automatically. BYOK requests bill at your own rate with OpenAI. To use Sol in a coding agent, run vercel ai-gateway coding-agents setup to connect your agents to AI Gateway, then select openai/gpt-5.6-sol in the agent's model settings. See the coding agents guide for setup details. Try it in the playground, or browse every language model on the AI Gateway. Read more
