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.

OpenRouter

  • No free tier; all usage incurs cost
  • Pricing varies by model; specific rates not published on main site without account access
  • Adds latency through additional routing layer compared to direct provider APIs
  • Dependent on upstream provider uptime and API compatibility
