Deepgram Cost Tuning

Overview

Optimize Deepgram API costs through smart model selection, audio preprocessing to reduce billable minutes, usage monitoring via the Deepgram API, budget guardrails, and feature-aware cost estimation. Deepgram bills per audio minute processed.

Deepgram Pricing (2026)

Strategy	Savings	Effort
Remove silence from audio	10-40%	Low (ffmpeg one-liner)
Disable diarization when not needed	~50%	Low (remove option)
Use callback for long files	Indirect (no timeouts)	Low
Cache repeated transcriptions	20-60%	Medium (Redis)
Speed up audio 1.25x	20%	Low (ffmpeg)
Use Nova-2 instead of Nova-3	0% (same price)	None
Batch pre-recorded vs streaming	37% ($0.0043 vs $0.0059)	Medium

Issue	Cause	Solution
Budget exceeded	No controls	Enable budget check before transcription
Unexpected charges	Diarization always on	Make diarization opt-in
Usage API empty	Wrong project ID	Get ID from `getProjects()`
Cost spike	Batch job without limits	Set concurrency limits + budget cap
