model-serving ai-gateway coding-agents inference-speed streaming

GLM 5.3 FlashX now serves at 200 tokens/sec

Z.ai's multimodal coding model available on Vercel AI Gateway with ~200 tokens/second inference speed for streaming agents and interactive tools.

Summary

Faster token throughput directly reduces latency in coding agents and tool loops where users wait on generated output. Integrates via unified API gateway with cost tracking, failover, and no platform fees.

Why it matters

Implementation verdict

Replaces slower Z.ai model variants for streaming workflows. Requires AI Gateway API key and model string `zai/glm-5.3-flashx`. Setup is trivial (`npx vercel ai-gateway setup`) and works today across Claude Code, Codex, Hermes, and OpenAI-compatible clients. Worth trying now if you run inference-heavy agents.
