The short version

  • Only Deepgram has a free tier, so it costs nothing to try first.
  • Each has a real cost: Anthropic API pricing varies significantly by model tier; Deepgram pricing is entirely usage-based, so total cost can be harder to predict than flat subscription tools.
  • They diverge on capability: Anthropic API covers Multiple models, Deepgram covers Flux speech-to-text.
  • Prices and features above were last checked on 30 August 2026.
