HappyHorse 1.1 text-to-video on Model Studio
Alibaba Cloud Model Studio Trial credit
The catch: When a model’s quota runs out or expires, calls are billed pay-as-you-go unless you switch on ‘Free Quota Only’, which is off by default. You must complete your Alibaba Cloud account information before activating, the base URL needs your workspace ID, and a new account does not get a second quota.

Before you ship on it
- When a model’s quota runs out or expires, calls are billed pay-as-you-go unless you switch on ‘Free Quota Only’, which is off by default. You must complete your Alibaba Cloud account information before activating, the base URL needs your workspace ID, and a new account does not get a second quota.
- Model Studio is a paid commercial cloud service; the free-quota page limits only scope (real-time inference in Singapore), not purpose. Alibaba Cloud International product terms apply.
- Free tiers are shared capacity: treat the limits as a ceiling, not a promise, and keep a paid fallback.
