AI BriefingGPT-5.6 Sol: 50% Discount at Lower Prices
Key point
OpenAI has lowered the price of GPT-5.6 Sol and is offering a 50% discount on Vercel AI Gateway until September 18.
Details
OpenAI has reduced the list price of GPT-5.6 Sol, and the 50% discount on Vercel AI Gateway applies to the new lower prices until September 18. As a result, input costs have decreased by 20%, and output costs have been reduced to one-third.
The discount applies to all OpenAI service tiers, with rates per million tokens for requests up to 272K tokens as follows:
- Default: Input $2.00 / Output $10.00
- Flex: Input $1.00 / Output $5.00
- Priority: Input $4.00 / Output $20.00
Cached tokens, cache writes, long-context requests exceeding 272K, and US region rates are also adjusted by the same ratios. The model ID remains unchanged, so existing requests will automatically be billed at the new prices, while BYOK (Bring Your Own Key) requests are billed at OpenAI's own rates.
To use Sol in coding agents, run vercel ai-gateway coding-agents setup to connect the agent to AI Gateway, then select openai/gpt-5.6-sol in the model settings.
