Our verdict

Deepgram suits teams that live in audio: transcription, multilingual recognition and text to speech from one speech specialist, not a general chat catalogue. Founded 2015, it trades catalogue breadth for depth in speech, a good trade for voice products and a poor one for long-context text work.

Pros and cons

Pros

  • Published compliance list is SOC 2 Type 1 & Type 2, HIPAA and GDPR, which covers most regulated-buyer checklists up front.
  • Hosted open models and first-party ones sit in the same catalogue, with Whisper Large and Deepgram Whisper Cloud listed alongside Flux and Nova models in Flux English, Flux Multilingual and Nova 3 Monolingual.
  • New signups get a free credit with no credit card required, so a first accuracy test on your own audio costs nothing to start.

Cons

  • Support runs on help centre and community only, so teams that want live help on a call need to budget for it elsewhere.
  • Input price from $0.30 and output price from $0.60 sit above the €0.08 and €0.23 medians for this group.
  • A context window of 150,000 ranks 60 of 72 here, well under the 1,000,000 median.

Scored 8.7 / 10 by DeployCue.

Who it suits

  • Teams building call transcription, voice agents or media tagging that want recognition and synthesis from one vendor.
  • Regulated buyers whose checklist starts with SOC 2 Type 1 & Type 2, HIPAA and GDPR.
  • Developers testing speech quality on their own recordings with the signup credit and no card required.

Who should look elsewhere

  • Anyone shopping on the lowest entry rate: Salad's input price from $0.06 is well below Deepgram's $0.30.
  • Teams wanting general-purpose text, image and audio models in one catalogue: Azure AI Foundry lists them in gpt 6 astra, gpt 6 luna and gpt 6 sol.
  • Buyers aggregating many open-weight families behind one gateway: Supascale AI lists them in DeepSeek V4 Pro, GPT 5.6 Sol and GPT 5.6 Terra.

Frequently asked questions

What does Deepgram charge for input and output?+

Input price from $0.30 and output price from $0.60 are Deepgram's entry rates. Both sit above the €0.08 and €0.23 medians for this group, so short runs cost little while steady volume costs more than gateways built around text models.

Can I try Deepgram without spending?+

New signups receive a free credit and no credit card is required to claim it. The entry rates behind that credit are $0.30 for input and $0.60 for output, so send a sample recording, check accuracy on your own audio, and only then decide whether ongoing volume is worth it.

Which models are on offer?+

The published set in Flux English, Flux Multilingual and Nova 3 Monolingual covers both directions of speech work. Flux and Nova handle English and multilingual recognition, the Whisper entries add an open-model path, and Flux TTS with the Aura models cover synthesis on the same account.

How much context fits in one request?+

The largest context window listed is 150,000, which ranks 60 of 72 brands on that measure. The group median is 1,000,000, so teams feeding very long transcripts should check the window before committing.

Is it compliant enough for regulated work?+

The published list is SOC 2 Type 1 & Type 2, HIPAA and GDPR. Those cover the frameworks regulated buyers ask about first, and certification scope can differ by product, so confirm the exact product and your own region's requirements with the vendor before signing.

What support can I reach?+

Support runs on help centre and community: a help centre and a community. Phone and live chat are not among the listed channels, so teams that need a named contact on a call should plan for documented answers instead.

How does it compare with Salad, Azure AI Foundry and Supascale AI?+

Deepgram stays inside speech, with Flux English, Flux Multilingual and Nova 3 Monolingual as its published catalogue. Salad's input price from $0.06 is lower for a raw entry rate, Azure AI Foundry lists general-purpose models in gpt 6 astra, gpt 6 luna and gpt 6 sol, and Supascale AI gathers open families in DeepSeek V4 Pro, GPT 5.6 Sol and GPT 5.6 Terra.
