Select `zai/glm-5.3-flashx` inside the agent.\n\nAI Gateway provides a unified API for calling models, tracking usage and cost, and configuring retries, failover, and performance optimizations for higher-than-provider uptime. It includes built-in [custom reporting](https://vercel.com/changelog/custom-reporting-ai-gateway), [budgets for API keys](https://vercel.com/docs/ai-gateway/authentication-and-byok/api-keys), [routing rules](https://vercel.com/docs/ai-gateway/models-and-providers/routing-rules), and more.\n\nAI Gateway reflects provider pricing with no markup and does not charge a platform fee on inference, including on [Bring Your Own Key](https://vercel.com/docs/ai-gateway/authentication-and-byok/byok) (BYOK) requests.\n\nTry [GLM-5.3-FlashX in the model playground](https://vercel.com/ai-gateway/models/glm-5.3-flashx), or [view all language models](https://vercel.com/ai-gateway/models?type=text) available on AI Gateway.", "url": "https://wpnews.pro/news/glm-5-3-flashx-now-available-on-ai-gateway", "canonical_source": "https://vercel.com/changelog/glm-5-3-flashx-now-available-on-ai-gateway", "published_at": "2026-09-18 00:00:00+00:00", "updated_at": "2026-09-18 18:55:19.479965+00:00", "lang": "en", "topics": ["ai-products", "large-language-models", "ai-agents", "ai-infrastructure", "developer-tools"], "entities": ["Vercel", "GLM 5.3 FlashX", "AI Gateway", "Z.ai"], "alternates": {"html": "https://wpnews.pro/news/glm-5-3-flashx-now-available-on-ai-gateway", "markdown": "https://wpnews.pro/news/glm-5-3-flashx-now-available-on-ai-gateway.md", "text": "https://wpnews.pro/news/glm-5-3-flashx-now-available-on-ai-gateway.txt", "jsonld": "https://wpnews.pro/news/glm-5-3-flashx-now-available-on-ai-gateway.jsonld"}}
