GLM-ASR API pricing

zai/glm-asr-2512

Speech-to-text. GLM-ASR by Z.ai, routed through INFRO on a Z.ai account you connect — alongside every other provider you run. Z.ai bills you for it directly, on that account and at your own rate. INFRO adds routing, failover, request logs, cost attribution and policy around it, and takes no part of what you pay Z.ai.
