GLM-5.3 50% Off on Vercel AI Gateway Via DigitalOcean

What shipped

Vercel AI Gateway added a promotional GLM-5.3 route served by DigitalOcean at 50% off, running through Tuesday, September 8, 2026.

What changed

Calls to the promo name zai/glm-5.3-promo-50 get the discounted rate but route only to DigitalOcean — no fallback — and stop serving when the offer ends. Using the standard zai/glm-5.3 name with DigitalOcean set as the preferred provider keeps the discount while preserving fallback routing. The deal is live now on AI Gateway, no provider account required.

Why a builder cares

A week of 50% off GLM-5.3 is a cheap, low-risk window to benchmark quality, latency, and cost against your default provider before you commit traffic — and the promo name keeps the experiment from silently bleeding into fallbacks.
