# GLM-5.3 is 50% off through DigitalOcean on AI Gateway

By Steven Van · 2026-09-02

GLM-5.3 is 50% off on AI Gateway through Tuesday, September 8, in partnership with DigitalOcean.

[Vercel](<https://creatorstoolbox.com/tools/vercel>)'s [AI Gateway](<https://vercel.com/changelog/glm-5-3-is-50-off-through-digitalocean-on-ai-gateway>) is offering GLM-5.3 at 50% off through DigitalOcean until Tuesday, September 8. To get the discounted rate, use the promo model name **zai/glm-5.3-promo-50**, which routes only to DigitalOcean with no fallback and stops working once the offer ends.

To keep working past September 8, use the standard name **zai/glm-5.3** instead, with providerOptions.gateway set to order: \['digitalocean'\]. This prefers DigitalOcean at its usual rate but falls back to other providers if needed. GLM-5.3 takes text input, with a 1M token context window and a maximum output of 128K tokens. Discounted requests show up in the spend dashboard with a normal trace. The model can also be selected inside coding agents such as Claude Code, Codex, OpenCode, Cursor and Pi via vercel ai-gateway coding-agents setup.
