## Why Included

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.

## Source Summary

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**.

## Practical Implication

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.

## Agent-Ready Context

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.

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.

## Connected Context

Feed7 judgment across 525 accumulated Signals:

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.

- [Gemini 3.7 Flash now available on AI Gateway for 50% off](https://feed7.dev/p/gemini-3-7-flash-now-available-on-ai-gateway-for-50-off-040tuet) — Both promotions create lower-cost evaluation windows through the same agent clients and Gateway controls, while requiring a later decision based on normal pricing and workload results.
- [GLM 5.2 free for eve agents through August 27 via Blackbox on AI Gateway](https://feed7.dev/p/glm-5-2-free-for-eve-agents-through-august-27-via-blackbox-on-ai-gateway-0td7ioc) — The free GLM period reinforces that temporary pricing can reduce evaluation friction but supplies no evidence for a lasting model replacement.
- [Alishahryar1/free-claude-code](https://feed7.dev/p/free-claude-code-02z06gq) — The local proxy offers broader provider portability, but contrasts with this managed discount by shifting credential custody, compatibility, and gateway maintenance to the operator.

## Uncertainty

- 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.
