Nemotron 3.5 ASR API pricing

nvidia/nemotron-3.5-asr

Speech-to-text. Nemotron 3.5 ASR by NVIDIA, routed through INFRO on a NVIDIA account you connect — alongside every other provider you run. NVIDIA 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 NVIDIA.
