What it is

Gladia wraps Whisper-class models in a developer-friendly API with diarization, 99 languages, and competitive per-minute pricing. A reasonable alternative to self-hosting faster-whisper when you want someone else to operate the GPUs. Last price check: 2026-04-20.

Best for: Teams who like the Whisper model family but don't want to run GPUs.
Watch out for: Smaller ecosystem than AssemblyAI/Deepgram; HIPAA on enterprise tiers only.
