GPT-5.6 Sol is 50% off on AI Gateway for the next month
Vercel cut GPT-5.6 Sol pricing by 50% through September 18, making direct AI Gateway runs cheaper across every tier without changing model IDs or agent configs.
GPT-5.6 Sol is **50% off through September 18** for requests billed directly through Vercel AI Gateway’s OpenAI provider. Default pricing is now **$2.50 input / $15 output per million tokens**.
Existing requests use the lower rate without a model-ID change. Builders can connect Claude Code, Codex, OpenCode, or Pi and select **openai/gpt-5.6-sol** to test harder agent tasks at the temporary price.

Existing requests use the lower rate without a model-ID change. Builders can connect Claude Code, Codex, OpenCode, or Pi and select **openai/gpt-5.6-sol** to test harder agent tasks at the temporary price. The offer excludes **BYOK requests**. It covers all gateway tiers, regions, token types, caching, and long-context use, but the material gives no post-promotion pricing commitment beyond the original rates.
The discount lowers the cost of a time-bounded GPT-5.6 Sol evaluation without requiring client or model-ID migration, but it does not establish a durable routing economy. Teams should use the window to measure difficult-task quality and token consumption, then reassess against the original rate because BYOK is excluded and post-promotion pricing is unchanged.
