The short version

  • Only Deepgram has a free tier, so it costs nothing to try first.
  • Each has a real cost: Amp purchased credits expire 12 months after purchase and subscription usage expires monthly, and Enterprise workspaces are billed at a 50 percent markup over individual and team rates, as of August 2026.; Deepgram pricing is entirely usage-based, so total cost can be harder to predict than flat subscription tools.

Where each one falls short

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

Amp

  • Purchased credits expire 12 months after purchase and subscription usage expires monthly, and Enterprise workspaces are billed at a 50 percent markup over individual and team rates, as of August 2026.

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.
