Alibaba Cloud Tightens API Access for BaiLian Platform
Alibaba Cloud Adjusts API Rate Limits on BaiLian Platform
In a move to better manage platform resources, Alibaba Cloud announced significant changes to its API rate limiting policy for the BaiLian large model service platform. The new measures take effect April 28, 2026.
What's Changing
The multimodal interaction gateway will now have a default limit of 10 queries per second (QPS). According to Alibaba Cloud's calculations, this allocation should support:
- 600 sessions per minute
- 36,000 sessions per hour
The company maintains this quota will satisfy most development and routine business operation needs.
Who's Affected
Developers working with BaiLian's APIs should review their current usage patterns before the changes take effect. However, there's an important exception:
"Customers who previously upgraded their quotas through official channels won't see any changes to their existing permissions," an Alibaba Cloud spokesperson confirmed.
Why Now?
The adjustment reflects growing demand for large model services across Alibaba Cloud's customer base. By implementing more granular traffic controls, the company aims to:
- Ensure stable service for all users
- Better balance resources between individual developers and enterprise clients
- Maintain platform performance during peak usage periods
Key Points:
- New rate limits take effect April 28, 2026
- Default QPS set at 10 (600 sessions/minute)
- Existing upgraded quotas remain unchanged
- Developers should assess current usage patterns
