## Source excerpt

GPT-5.6 Sol, the flagship of OpenAI's GPT-5.6 series, is 50% off on AI Gateway through September 18. The discount applies on the OpenAI provider to all token types, tiers, regions, and modes, and it is available only on requests running directly through AI Gateway (not BYOK). Pricing: 50% off Service tier New price per M tokens (input / output) Original price per M tokens (input / output) Default $2.50 / $15.00 $5.00 / $30.00 Flex $1.25 / $7.50 $2.50 / $15.00 Priority (fast mode) $5.00 / $30.00 $10.00 / $60.00 The discount applies on the same terms everywhere else the model is priced: across every service tier, including fast mode, and to cached tokens, cache writes, long-context requests, and different regions. It covers requests billed through AI Gateway on the OpenAI provider. BYOK requests run on your own provider accounts and bill at whatever rate you have with them. The model ID is unchanged, so requests you already send pick up the discounted 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, run vercel ai-gateway coding-agents setup to connect Claude Code, Codex, OpenCode, or Pi, then select openai/gpt-5.6-sol inside the agent. The 50% discount will apply there. Get started Create an API key in the AI Gateway section of your dashboard, or try the model in the browser first from its playground page. Read more
