Deepgram Pricing 2026: The Sub-Cent Myth

TL;DR: Deepgram pricing starts with $200 free credit, then Nova-3 speech-to-text runs from $0.0048 per minute. The catch: that sub-cent rate is only transcription. The bundled Voice Agent API costs $0.075 per minute (about $4.50/hour), and text-to-speech is billed separately at $0.030 per 1,000 characters. Cheap STT is not the same as a cheap voice agent.

Deepgram bills speech-to-text, text-to-speech and voice agents on three separate meters.

Deepgram is one of the most-used speech APIs behind voice agents and call analytics, and its headline speech-to-text price is genuinely tiny. As of July 2026, that is exactly why people misjudge the cost. The sub-cent number is real, but it only covers transcription. A working voice agent stacks three meters, and the one that matters most is 15 times the sticker you first see.

What are the Deepgram pricing plans in 2026?

Deepgram has two self-serve plans plus Enterprise: Pay As You Go (no minimums, no expiration, no card required) and Growth (prepaid credits, up to 20 percent off, starting around $4,000 per year). Every new account also gets $200 in free credit. According to Deepgram's pricing page (checked July 2026), the plans share the same models; Growth just discounts the rates and raises concurrency.

For a solo builder or freelancer, Pay As You Go is the right starting point because you owe nothing until you use it and the $200 credit lasts a long time. Growth only makes sense once your monthly Deepgram spend is high enough that a yearly prepay and a ~20 percent discount beat the flexibility of paying per unit.

How much does Deepgram speech-to-text cost per minute?

Deepgram Nova-3 speech-to-text costs $0.0048 per minute on a promotional streaming rate and $0.0077 per minute standard, per Deepgram's pricing page (checked July 2026). Multilingual is $0.0058 per minute promotional. On the Growth plan those drop to roughly $0.0042 and $0.0050 per minute.

That is the number everyone quotes, and it is honestly cheap: an hour of transcription is well under 50 cents. Add-ons stack on top, though. Speaker diarization and PII redaction each add $0.0020 per minute, while smart formatting is included. If you only need transcription, this is one of the best rates in the market. If you need a talking agent, keep reading.

How much does the Deepgram Voice Agent API cost?

The Deepgram Voice Agent API costs $0.075 per minute on the Standard tier, roughly $4.50 per hour, and bundles speech-to-text, text-to-speech and an LLM into one call. Bring-your-own TTS drops it to $0.065 per minute; bring your own LLM and TTS and it falls to $0.050 per minute. The Advanced tier is $0.163 per minute.

This is the sub-cent myth in one line. The transcription rate is $0.0048 per minute, but the full conversational agent is $0.075 per minute, about 15 times higher, because it now includes generating speech and running a model. When you quote a client for an AI phone receptionist, budget the Voice Agent API rate, not the STT rate, or your margins evaporate on the first busy month.

What do you get with the Deepgram free credit?

The Deepgram free credit is $200, requires no credit card, and does not expire, which makes it one of the more generous trials in voice AI. Deepgram states it covers roughly 220 hours of speech-to-text or about 6.67 million text-to-speech characters, drawn down against whatever you actually use.

In practice that is enough to build and demo a real voice agent before paying a cent. A useful tactic for freelancers: build a client's proof-of-concept agent entirely on the free credit, show it working, then move to Pay As You Go once the contract is signed. Just remember the credit draws down fastest on the Voice Agent API, not on plain transcription.

Deepgram vs Cartesia pricing: which is cheaper for voice agents?

For transcription, Deepgram is cheaper at under a cent per minute; for text-to-speech, Cartesia's Sonic is often cheaper and faster with a 90ms time-to-first-audio, versus Deepgram Aura-2 at $0.030 per 1,000 characters. For a complete agent, you compare Deepgram's bundled $0.075 per minute against Cartesia's telephony plus model credits.

The honest takeaway: neither tool is universally cheaper. Deepgram wins when speech-to-text is the bulk of your workload or you want one bundled agent API. Cartesia wins on fast, cheap text-to-speech and a code-first agent platform. Plenty of builders run Deepgram for transcription and a separate specialist for the voice, then compare the combined bill.

Frequently asked questions

Is Deepgram free to try?
Yes. Deepgram gives every new account $200 in free credit with no credit card required, and the credit does not expire. That covers roughly 220 hours of speech-to-text or about 6.67 million text-to-speech characters, which is plenty to prototype a voice agent before you pay anything.

How much does Deepgram speech-to-text cost per minute?
Deepgram Nova-3 speech-to-text costs $0.0048 per minute on a promotional streaming rate, and $0.0077 per minute at the standard rate, on the Pay As You Go plan as of July 2026. Multilingual is slightly higher at $0.0058 per minute promotional. The Growth plan shaves roughly 10 to 20 percent off those rates.

How much does the Deepgram Voice Agent API cost?
The Deepgram Voice Agent API Standard tier costs $0.075 per minute on Pay As You Go, which is about $4.50 an hour, and bundles speech-to-text, text-to-speech and an LLM. Bringing your own TTS drops it to $0.065 per minute, and bringing your own LLM and TTS drops it to $0.050 per minute. The Advanced tier runs $0.163 per minute.

What is the difference between Pay As You Go and Growth?
Pay As You Go has no minimums, no expiration and no card required, and you pay the published per-unit rates. Growth is a prepaid, committed-spend plan starting around $4,000 per year that discounts those rates by up to 20 percent and raises concurrency limits. Enterprise sits above both with custom terms, self-hosting and compliance.

Is Deepgram cheaper than Cartesia?
For speech-to-text, Deepgram is very cheap at under a cent per minute. For text-to-speech, Cartesia's Sonic is often cheaper and faster with a 90ms time-to-first-audio, while Deepgram's Aura-2 is $0.030 per 1,000 characters. For a full voice agent, compare Deepgram's bundled $0.075 per minute against Cartesia's telephony plus credits. Neither is universally cheaper; it depends on which pieces you use.

Does Deepgram charge for silence?
Deepgram bills for the audio duration you send, so long stretches of silence in an uploaded file still count as processed minutes. For live streaming voice agents this is rarely an issue because you are billed for actual connection time, but for pre-recorded batch jobs it pays to trim dead air before you upload.

Can I self-host Deepgram?
Self-hosting is available, but only on Enterprise contracts, not on Pay As You Go or Growth. Enterprise adds on-premise or private-cloud deployment, HIPAA business associate agreements, custom SLAs and volume discounts. If you handle regulated health or financial audio at scale, that is the tier to ask about.

Bottom line

Deepgram is a top pick when transcription is the core of your product, and the $200 no-expiry credit makes it painless to try. Use Pay As You Go until your spend is high enough that Growth's up-to-20-percent discount pays for the yearly commitment. Just do not confuse the sub-cent speech-to-text rate with the cost of a talking agent: the Voice Agent API is $0.075 per minute, and text-to-speech is metered separately. Price the pieces you will actually use, and Deepgram is one of the strongest, most transparent options in voice AI.
