The discount applies to all token types, tiers, regions, and modes for requests billed through AI Gateway on the OpenAI provider, with no code change required.", "body_md": "[GPT-5.6 Sol](https://vercel.com/ai-gateway/models/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).\n\nService tier | New price per M tokens (input / output) | Original price per M tokens (input / output) |\n|---|---|---|\nDefault | $2.50 / $15.00 | $5.00 / $30.00 |\nFlex | $1.25 / $7.50 | $2.50 / $15.00 |\nPriority (fast mode) | $5.00 / $30.00 | $10.00 / $60.00 |\n\nThe 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.\n\nIt covers requests billed through AI Gateway on the OpenAI provider. [BYOK](https://vercel.com/docs/ai-gateway/authentication-and-byok/byok) requests run on your own provider accounts and bill at whatever rate you have with them.\n\nThe model ID is unchanged, so requests you already send pick up the discounted rate with no code change:\n\nSol takes a reasoning effort up to `max`\n\nfor the hardest problems, accepts text, image, and PDF input, and carries a long context window.\n\nTo use it in a [coding agent](https://vercel.com/docs/ai-gateway/coding-agents), run `vercel ai-gateway coding-agents setup`\n\nto connect Claude Code, Codex, OpenCode, or Pi, then select `openai/gpt-5.6-sol`\n\ninside the agent. The 50% discount will apply there.\n\n[Create an API key](https://vercel.com/d?to=%2F%5Bteam%5D%2F%7E%2Fai-gateway&title=AI+Gateway) in the AI Gateway section of your dashboard, or try the model in the browser first from its [playground page](https://vercel.com/ai-gateway/models/gpt-5.6-sol).", "url": "https://wpnews.pro/news/gpt-5-6-sol-is-50-off-on-ai-gateway-for-the-next-month", "canonical_source": "https://vercel.com/changelog/gpt-5-6-sol-is-50-off-on-ai-gateway-for-the-next-month", "published_at": "2026-08-17 00:00:00+00:00", "updated_at": "2026-08-17 15:40:32.718780+00:00", "lang": "en", "topics": ["ai-products", "large-language-models", "ai-infrastructure"], "entities": ["OpenAI", "GPT-5.6 Sol", "Vercel", "AI Gateway"], "alternates": {"html": "https://wpnews.pro/news/gpt-5-6-sol-is-50-off-on-ai-gateway-for-the-next-month", "markdown": "https://wpnews.pro/news/gpt-5-6-sol-is-50-off-on-ai-gateway-for-the-next-month.md", "text": "https://wpnews.pro/news/gpt-5-6-sol-is-50-off-on-ai-gateway-for-the-next-month.txt", "jsonld": "https://wpnews.pro/news/gpt-5-6-sol-is-50-off-on-ai-gateway-for-the-next-month.jsonld"}}
