Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Deepgram

  • Pricing is entirely usage-based, so total cost can be harder to predict than flat subscription tools.
  • The Growth plan requires a minimum $4K/year commitment to unlock discounted rates.
  • Enterprise features and custom SLAs require a direct sales conversation rather than self-serve signup.
  • Some promotional per-minute rates are time-limited, meaning long-term pricing may differ from current promotional rates.

Grok

  • Pricing is not published; all access requires sales contact or account negotiation
  • Limited ecosystem compared to OpenAI and Anthropic; fewer third-party integrations
  • Organisational reputation tied to Elon Musk; policy or direction changes may affect service continuity
