B.AI Continues Free Access to GLM-5.3-Flash, Maintaining Zero-Cost Development

On September 8, B.AI announced that GLM-5.3-Flash will continue to provide zero-cost API access for global developers after Zhipu's limited-time 50% discount ends at 24:00 on September 9, eliminating the need to adjust usage habits due to upstream price changes.

As a leading popular model on the B.AI platform by call volume, GLM-5.3-Flash features 320B total parameters with 18B activated parameters, supports 1M ultra-long context, and combines rapid response with robust reasoning capabilities, making it a foundational standard for developers' daily code assistance, large-scale data processing, and high-frequency text generation. As an intelligent global settlement layer connecting models, agents, and value flow, B.AI continues to absorb uncertainty from upstream cost fluctuations, allowing developers to focus solely on innovation while the platform handles the rest.
