Deepgram is positioned as speech recognition models with separate speech generation and managed voice-agent APIs. Pipecat is positioned as open-source Python orchestration for a voice stack assembled by developers. Start by deciding who owns the missing layers, then inspect the documented differences below.
STT and Developer Frameworks are different product categories. An underlying engine or framework is not a complete substitute for a deployed agent workflow.
18 jointly documented catalog fields. This measures evidence coverage, not equivalent quality or an overall winner.
Test opening hours, booking conflicts and an unanswered transfer.

STT audio minutes, TTS characters and Voice Agent connection minutes are distinct.
Framework open source; Cloud compute, reservation, transport, recording and providers separately priced.
External provider and telephony bills excluded where applicable. Do not infer a complete monthly ceiling.
Compute only. Transport/models/recording and reserved idle time excluded.
Billable open connection time is not just spoken audio.
Different units cannot be normalized without usage and provider assumptions.
Growth is annual prepaid commitment, not invented monthly subscription.
Public component table and Enterprise sales path were reviewed; an exact platform subscription floor, contractual minimum and billing-rounding policy were not established. Per-minute display alone does not prove per-second metering.
No fixed included agent minutes inferred from credit dollars.
Does not make hosting or model inference free.
Initial credits, Growth commitments and tier rates are documented; no recurring free plan or universal rounding/contract terms inferred.
This is the audio-filter allowance overage, not an all-in call rate.
Agent pricing covers selected tier and components; full workload determines bill.
Enterprise integrated inference billing by agreement.

Carrier, hosting, model tier and BYO usage prevent a universal full monthly or per-minute ceiling.
No all-in ceiling from minutes alone: reservation, transport, providers, recording and carrier legs vary.
