# AI Gateway: GPT

By Steven Van · 2026-07-30

On AI Gateway, GPT-5.6 Luna and GPT-5.6 Terra are now cheaper and GPT-5.6 Sol is faster.

On [Vercel](<https://creatorstoolbox.com/tools/vercel>)'s [AI Gateway](<https://vercel.com/changelog/ai-gateway-gpt-5-6-pricing-speed-updates>), GPT-5.6 Luna and GPT-5.6 Terra are cheaper and GPT-5.6 Sol runs faster in fast mode. Since AI Gateway adds no markup on token pricing, the changes reach developers at the upstream rate, for both short and long context.

- **openai/gpt-5.6-luna**: 80% price reduction, to $0.2 per 1M input tokens and $1.2 per 1M output tokens (short context).

- **openai/gpt-5.6-terra**: 20% price reduction, to $2 per 1M input tokens and $12 per 1M output tokens (short context).

- **openai/gpt-5.6-sol**: price unchanged, but fast mode is now 2.5x faster, up from 1.5x.

Model IDs haven't changed, so existing requests pick up the new rates and speed without any code changes.
