ZenMux GLM Flash free routes

The terms in full

ZenMux lists z-ai/glm-4.6v-flash-free and z-ai/glm-4.7-flash-free as active routes with a $0 effective price on both input and output, each marked Free and Rate Limit on 2026-09-28. Access requires a ZenMux account and an API key, created under either the Pay As You Go plan or the paid Builder Plan subscription. The public pages do not state a card requirement or a numeric free-route quota. ZenMux documents that an account must keep a non-negative balance even for free tiers, while some models can require a positive balance. Prior free routes have sunset without becoming permanent, so the lineup is dynamic.

• When it runs out Not stated by the provider.
• Clock No fixed expiry is stated for either route. Both model pages showed Active with no end date on 2026-09-23.
• Region No region restriction stated by the provider.
