GLM 5.3 FlashX Is Now Available on Vercel’s AI Gateway, and It’s Not the Model You’d Expect
Vercel added GLM 5.3 FlashX to its AI Gateway on September 18, 2026. It’s a faster serving option for Z.ai’s GLM-5.3-Flash model, not the larger flagship GLM-5.3, and the speed comes at a real price and latency cost.
