How much does a realtime AI avatar API cost in 2026? The $5/hour answer
Realtime AI avatar API pricing compared across LiveAvatar, D-ID, and HeyGen — normalized to dollars per hour of live streaming — and why we anchored our plans at about $5/hour.
Every realtime avatar platform prices in its own currency — credits, wallets, plan minutes — which makes "what does this actually cost?" weirdly hard to answer. So here is the answer, normalized to the only unit that matters for a live product: dollars per hour of avatar on air. All competitor numbers were verified against official pricing pages in June 2026; check them before you commit, because they move.
Realtime AI avatar API pricing, normalized to $/hour
| Platform | Model | Effective realtime rate |
|---|---|---|
| TIC Realtime Avatar | Plan minutes, full stack included | ~$5/hour ($4.20–5.10 by plan) |
| LiveAvatar (HeyGen's realtime spin-off) | Credits; 1 credit = 30s in FULL mode | ~$12–14/hour FULL · ~$6–7/hour LITE (bring your own LLM/TTS/ASR) |
| D-ID API plans | Credits; 1 credit = 30s streaming | ~$30–34/hour streaming |
| HeyGen main API | USD wallet, per second | No realtime — generated video at $3/min ($180/hour equivalent) |
| Synthesia | Plan-bundled API | No realtime product; 360 video min/year on the $89/mo Creator plan |
Why we anchored at $5/hour
Realtime rendering used to be priced like a luxury because GPUs were treated as scarce. Our renderer is engineered for cost: avatars register once from a single image or short clip, stay warm in a cache, and stream audio-clocked video efficiently enough that $5/hour leaves a healthy margin — so we priced there instead of at the market's $12–30/hour habit. Concretely:
- Developer — $49/mo for 600 minutes (10 hours), then $0.085/min
- Studio — $249/mo for 3,000 minutes (50 hours), then $0.08/min
- Scale — $999/mo for 13,000 minutes (216 hours), then $0.07/min
- Sandbox — free, 5 minutes every month, no card
Avatar creation is $1 beyond your plan's included count (the same rate HeyGen charges per API avatar). There is no separate fee for the LLM, the voice, or the streaming infrastructure — a minute is a minute.
What that means per session
Pricing only becomes real at the session level. At $5/hour: a five-minute support conversation costs about $0.42; a twenty-minute companion session about $1.70; an hour-long livestream $5. Run the same numbers on a $30/hour platform and the livestream costs more than most creators earn from it.
The fine print that changes the math elsewhere
- Credit conversions are where budgets die. "1,000 credits" means 500 realtime minutes on one platform and 250 on another. Always convert to $/hour before comparing.
- "Bring your own stack" prices hide three more bills. LITE-mode rates exclude the LLM, TTS, and ASR you now have to buy and operate yourself.
- Session caps are a price. A plan whose sessions end at five minutes prices long-form use cases out regardless of the per-minute rate.
Run your own number
Estimate monthly on-air hours, multiply by the normalized rate, and add the platform's fixed fees — then test the latency before believing any of it. Our free sandbox exists for that: register a character, hold a conversation, and check time-to-first-frame against your own budget before spending a dollar.
