GLM-5.3 Flash launches on Vercel AI Gateway

Multimodal model with 1M token context now routable through unified AI Gateway API; set model to `zai/glm-5.3-flash` to use.

Summary

Adds another provider option for vision-capable inference without managing separate API keys or retry logic. Integrates directly with coding agents (Claude Code, Cursor, etc.) via Gateway's agent setup CLI.

Why it matters

Implementation verdict

Replaces direct Z.ai API calls with Gateway routing. Requires `model` string change and optional agent setup CLI command. Worth trying now if already on AI Gateway; otherwise evaluate against existing provider stack for cost/latency tradeoff.
