How pricing works
These two tools don't price the same way, so the headline numbers below aren't directly comparable until you plug in your own volume.
- Deepgram (Per Usage) — Deepgram bills purely on usage. There is no fixed per-seat fee, so the monthly cost depends entirely on how much you consume.
- telli (Per Usage) — telli bills purely on usage — Custom. There is no fixed per-seat fee, so the monthly cost depends entirely on how much you consume.
Per-minute, per-credit and per-token rates exclude any downstream model, speech or telephony costs unless the vendor states otherwise.

What each is best for
Deepgram is worth it if… developers building voice-first products that need low-latency speech APIs at scale. Nova-2 STT is the workhorse — best price/performance for real-time transcription.
telli is worth it if… outbound sales teams in appointment-heavy verticals (solar, home services, insurance) who want AI voice agents that dial and qualify at scale without hiring more SDRs. Pricing is opaque and quote-driven — expect setup support that varies by tier and per-minute rates that need negotiation.
Bottom line: Similar positioning, closer to a preference call than a strategic one.
