Key point

Details
Vercel AI Gateway offers the GLM-5.3 model at a 50% discount until Tuesday, September 8, through a partnership with DigitalOcean.
During the discount period, using the promotional model name (zai/glm-5.3-promo-50) routes requests exclusively through DigitalOcean, with no fallback to other providers. Since this promotional model name will be discontinued when the discount ends, it should be treated as a temporary switch rather than hardcoded in your code.
To prioritize DigitalOcean even after the discount ends, specify order: ['digitalocean'] in providerOptions.gateway along with the standard model name (zai/glm-5.3). In this case, if DigitalOcean cannot handle the request, it will fall back to other providers, and standard rates will apply after the discount period.
GLM-5.3 supports text input and provides a 1M token context window and a maximum output length of 128K tokens. Discounted requests are also logged in the Vercel dashboard and tracked identically to other requests. To use it with coding agents like Claude Code or Codex, run vercel ai-gateway coding-agents setup and select zai/glm-5.3-promo-50.
