The new list prices are $4.00/$20.00 per million tokens for Default tier, $2.00/$10.00 for Flex, and $8.00/$40.00 for Priority, with effective prices after discount at $2.00/$10.00, $1.00/$5.00, and $4.00/$20.00 respectively.", "body_md": "OpenAI just lowered list pricing for [GPT-5.6 Sol](https://vercel.com/ai-gateway/models/gpt-5.6-sol). The 50% AI Gateway discount continues and applies to the new list price now through September 18th.\n\nThe 50% discount applies on every tier on the OpenAI provider, against the new list price.\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. The reduction is the same proportion on every tier: input is 20% lower than before and output is a third lower. Cached tokens, cache writes, and long-context requests above 272K move on the same terms, as do the US regional rates. Current rates for every model are on the [pricing page](https://vercel.com/docs/ai-gateway/pricing).\n\nThe discount itself has not changed, and neither has the date it ends. This is the same 50% off applied to a lower list price. Billing through AI Gateway picks this up automatically. [BYOK](https://vercel.com/docs/ai-gateway/authentication-and-byok/byok) requests run on your own account and bill at your rate with the provider.\n\nThe model ID (`openai/gpt-5.6-sol`\n\n) is unchanged, so requests you already send bill at the new 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, see the [coding agents guide](https://vercel.com/docs/ai-gateway/coding-agents), then run `vercel ai-gateway coding-agents setup`\n\nto connect agents like Claude Code, Codex, OpenCode, Cursor, Pi, and more, and select `openai/gpt-5.6-sol`\n\ninside the agent.\n\n[Try GPT-5.6 Sol in the playground](https://vercel.com/ai-gateway/models/gpt-5.6-sol) and [view all language models](https://vercel.com/ai-gateway/models?type=text) to get started with AI Gateway.", "url": "https://wpnews.pro/news/gpt-5-6-sol-pricing-drops-on-ai-gateway-and-50-discount-still-applies", "canonical_source": "https://vercel.com/changelog/gpt-5-6-sol-pricing-drops-on-ai-gateway-and-50-discount-still-applies", "published_at": "2026-08-21 00:00:00+00:00", "updated_at": "2026-08-21 20:14:07.000317+00:00", "lang": "en", "topics": ["ai-products", "ai-infrastructure", "large-language-models"], "entities": ["OpenAI", "GPT-5.6 Sol", "Vercel", "AI Gateway"], "alternates": {"html": "https://wpnews.pro/news/gpt-5-6-sol-pricing-drops-on-ai-gateway-and-50-discount-still-applies", "markdown": "https://wpnews.pro/news/gpt-5-6-sol-pricing-drops-on-ai-gateway-and-50-discount-still-applies.md", "text": "https://wpnews.pro/news/gpt-5-6-sol-pricing-drops-on-ai-gateway-and-50-discount-still-applies.txt", "jsonld": "https://wpnews.pro/news/gpt-5-6-sol-pricing-drops-on-ai-gateway-and-50-discount-still-applies.jsonld"}}
