Deepgram vs Groq (hosted Whisper)
This is the verified Deepgram vs Groq (hosted Whisper) breakdown: Deepgram (Developer-first realtime STT API for voice agents and transcription at scale) and Groq (hosted Whisper) (Ultra-fast, low-cost hosted Whisper transcription API (no realtime streaming)) are Speech-to-text APIs platforms, priced from $0.0043/min and $0.0019/min respectively. The bottom line, head-to-head facts, and true cost tiers follow.
Deepgram wins three of five use cases outright and ties the remaining two, making it the stronger all-around choice. For developers, it offers a broader SDK roster covering JS/TS, Python,.NET, Go, Java, and Rust compared to Groq's two official SDKs, plus websocket streaming that Groq simply does not support. For medical and compliance-sensitive teams, Deepgram provides a HIPAA BAA, PII redaction at $0.002/audio-min, and speaker diarization, none of which Groq offers. For voice agents, real-time websocket streaming at a vendor-claimed 300 ms latency is a hard requirement that Groq cannot meet without streaming support. Groq is cheaper at $0.00185/audio-min versus Deepgram's $0.0043/audio-min for batch, but the feature gaps are decisive across the winning use cases.

Groq (hosted Whisper) holds a clear price advantage at $0.00185/audio-min versus Deepgram's $0.0043/audio-min for batch work. However, Deepgram wins on two critical product-building capabilities: it offers a WebSocket streaming API while Groq (hosted Whisper) does not, and it ships official SDKs in six languages (JS/TS, Python,.NET, Go, Java, Rust) versus two for Groq (hosted Whisper). Both support word-level timestamps, but Deepgram also handles 100+ audio formats versus a handful for Groq. For developers building full-featured transcription products, the streaming API and broader SDK coverage outweigh the per-minute savings.
The available information covers speech-recognition API capabilities, pricing, and compliance, but none of it addresses the attributes that actually decide a dictation use case: which desktop or mobile platforms a dictation app runs on, whether audio is processed locally or sent to the cloud, AI-powered formatting or editing features, one-time versus subscription app pricing, or integrations with word processors and other apps. Neither tool's information speaks to these questions, so there is no basis to favor one over the other for personal voice-typing on a computer.
For clinical transcription under US healthcare privacy law, having a HIPAA BAA is the absolute requirement before any other consideration matters. Deepgram publishes a HIPAA BAA, while Groq (hosted Whisper) has no verified HIPAA BAA, which alone is disqualifying for most healthcare buyers. Beyond that gate, Deepgram also offers PII redaction as a paid add-on at $0.002/audio-min, while Groq (hosted Whisper) offers no PII redaction at all. Both tools support custom vocabulary boosting, both hold SOC 2 Type II certification, and self-hosting is available on both sides, so those attributes are level. Deepgram sweeps the two most critical clinical requirements, making the choice straightforward.
Both Deepgram and Groq (hosted Whisper) offer a self-host or on-premises option. Beyond that single shared fact, neither tool has published information on model weights license, hardware requirements, project maintenance status, or model size for the self-hosted deployment scenario. Those attributes are central to any decision about running a model on your own hardware, and without that data for either tool, no meaningful differentiation is possible. Confirming self-host availability alone cannot tip the scales when license terms, hardware specs, and project health all remain unpublished.
For voice agents, real-time streaming capability is the deciding factor. Deepgram offers WebSocket streaming with a claimed 300 ms latency, while Groq (hosted Whisper) has no WebSocket streaming API at all, making it unsuitable for live voice bot use. Deepgram also supports up to 150 concurrent WebSocket connections on its base pay-as-you-go plan, providing the concurrency voice agents need at scale. Both tools support custom vocabulary boosting. Deepgram's streaming rate of $0.0048/audio-min is the only option in play since Groq simply lacks streaming.
Deepgram vs Groq (hosted Whisper): common questions
Deepgram vs Groq (hosted Whisper): which is better for call centers?+−
Deepgram has a stronger call-center feature set, offering real-time streaming via WebSocket (which Groq hosted Whisper does not), plus speaker diarization, sentiment analysis, entity detection, PII redaction, and summarization as add-ons. Groq hosted Whisper lacks all of those features. Deepgram also provides a HIPAA BAA for compliance-sensitive deployments. The trade-off is cost: Deepgram's batch rate is $0.0043/audio-min versus Groq hosted Whisper's $0.00185/audio-min.
Does Deepgram or Groq (hosted Whisper) have a better free tier to test with?+−
Deepgram offers a $200 credit with no expiration and no credit card required. Groq's hosted Whisper provides a free tier with up to 28,800 audio seconds per day. Deepgram's credit gives more flexibility for burst testing, while Groq's free tier suits consistent daily experimentation.
Is Deepgram or Groq (hosted Whisper) better for multilingual transcription?+−
Groq (hosted Whisper) supports 99 languages and offers speech translation, while Deepgram supports 50 languages. Both tools support automatic language detection. If broad language coverage or translation is a priority, Groq (hosted Whisper) has the wider reach.
Does Deepgram or Groq (hosted Whisper) support real-time streaming transcription?+−
Deepgram supports WebSocket streaming with a vendor-claimed latency of 300 ms, and its pay-as-you-go plan allows up to 150 concurrent WebSocket connections. Groq (hosted Whisper) does not offer a WebSocket streaming API, making Deepgram the only option for real-time use cases.
Which tool is better for HIPAA-compliant healthcare applications, Deepgram or Groq (hosted Whisper)?+−
Deepgram offers a HIPAA BAA and is SOC 2 Type II certified. Groq (hosted Whisper) is SOC 2 Type II certified but does not list a published HIPAA BAA. If a signed BAA is a hard requirement, Deepgram is the documented option.
Does Deepgram support speaker diarization and PII redaction?+−
Deepgram offers both speaker diarization and PII redaction as paid add-ons, each priced at $0.002 per audio minute (about $0.12 per hour), on top of base transcription pricing. Groq (hosted Whisper) does not support either feature.
Does Deepgram or Groq (hosted Whisper) offer more audio intelligence features like sentiment analysis or summarization?+−
Deepgram includes sentiment analysis, entity detection, summarization, topics, and intents as token-priced add-ons. Groq hosted Whisper offers none of these features. For downstream analytics built directly into the STT pipeline, Deepgram has a clear advantage.
What are the file size limits when using Deepgram versus Groq (hosted Whisper) for batch transcription?+−
Deepgram accepts files up to 2 GB with a 10-minute processing timeout on the Nova model. Groq, running hosted Whisper, caps requests at 25 MB on the free tier and 100 MB on the developer tier. For large audio files, Deepgram's 2 GB limit is significantly more generous.
