Which one should you pick?
Pick NVIDIA Riva if
You’re building around teams with gpu clusters that need low-latency on-prem transcription.. Riva is NVIDIA's containerised speech stack, with Parakeet and Canary models that are genuinely competitive on English WER. You run it yourself, so latency and data residency are fully under your control, but you also own the GPU ops cost.
Pick OpenAI Whisper API if
You’re building around developers wanting raw transcription. Raw Whisper through OpenAI is still one of the cheapest ways to get high-quality transcription — $0.006/min for Whisper or gpt-4o-transcribe, and $0.
