GPT-5.6 and Muse Spark 1.1 land on Vercel AI Gateway

Vercel added OpenAI's GPT-5.6 family (Sol, Luna, Terra) and Meta's Muse Spark 1.1 as selectable models on AI Gateway, its unified routing layer for calling multiple model providers through one API and billing relationship.

Why it matters

New frontier models are usable from an existing Vercel AI Gateway integration on day one, without a separate provider account, contract, or SDK integration per model.

Who should care

Developers building on Vercel AI Gateway who want to try new frontier models

What you can do

Swap the model parameter in your existing AI Gateway calls to try GPT-5.6 Sol or Muse Spark 1.1 without changing your integration code.
