# GLM 5.2 now available on AI Gateway

By Steven Van · 2026-06-16

GLM 5.2 arrives on Vercel's AI Gateway with a 1M-token context window, up from 200K in the previous version.

The [Vercel](<https://creatorstoolbox.com/tools/vercel>) AI Gateway now offers GLM 5.2, a model built for long-horizon tasks that carries project-level engineering context across a single task and follows engineering standards more consistently. Its context window has been upgraded to **1M tokens**, up from 200K in GLM 5.1.

To use it, developers set the model to zai/glm-5.2 in the AI SDK. AI Gateway charges no markup on provider pricing and no platform fee on inference, including on Bring Your Own Key requests. Model rankings are tracked on the [AI Gateway leaderboard](<https://vercel.com/ai-gateway/leaderboards>).
