SuperMIA vs Retell AI: Pricing, Features & Real Cost (2026)
Honest cost math at 1K, 10K, and 100K minutes, verified feature gaps, and a clear buyer framework - Retell's modular pay-as-you-go voice platform versus SuperMIA's bundled voice-plus-chat credit pool.
The verdict
Retell is a developer-first, modular pay-as-you-go voice platform. SuperMIA is a bundled voice-plus-chat platform for ops and growth teams. Retell's page openly quotes $0.07–$0.31/min - the spread is real, because you pay stacked meters: voice infrastructure ($0.055/min) + your chosen LLM ($0.003–$0.16/min) + TTS ($0.015–$0.040/min) + telephony, plus $8/month per concurrent line beyond 20 and per-feature add-ons (knowledge base, guardrails, PII removal). Retell now offers chat too, but it's billed as a separate per-message meter. SuperMIA folds voice, chat, telephony, analytics, and compliance into one credit pool - $1,300/mo for 12,500 voice minutes at an effective $0.104/min, chat in the same pool. For pilots and variable volume with a technical team, Retell's true pay-as-you-go is excellent (and its 4.8 G2 rating is well earned). For predictable, bundled voice + chat without modular math, SuperMIA wins.
Two different products
Modular meters vs bundled credit pool
Retell and SuperMIA both ship production voice AI - and both now offer chat. The difference is how you're billed: Retell meters each component and add-on; SuperMIA charges one credit rate with everything in. Pick based on your volume, your team, and how predictable you need the invoice.
Retell AI - Modular Pay-as-you-go
Retell is developer-first voice infrastructure with no platform fee, no minimums, and no contracts - you pay only for what you use. You compose the stack: pick your LLM (GPT-5.x, Claude 4.5/4.6, Gemini 3.x), voice provider, and telephony. Live in minutes with $10 in free credits and ~600ms latency.
SuperMIA - Bundled Platform
SuperMIA charges on credits, not stacked meters. Every plan converts to voice minutes OR chat conversations from one pool at a consistent rate - telephony, knowledge base, analytics, and compliance included. The published rate is the total cost, not a base. Managed and no-code deployment, live voice in 48 hours.
- One credit pool converts to voice OR chat
- No per-line concurrency surcharge
- No per-feature add-on meters - it's all in
- HIPAA-aligned, BAA on eligible plans · SOC 2, GDPR, PCI DSS, ISO 27001
- Voice + Website + WhatsApp + Messenger + Instagram + SMS + Telegram
Where SuperMIA wins
Four verified advantages that matter in production
One rate vs a stacked meter
Retell's invoice adds voice infra ($0.055) + LLM ($0.003–$0.16) + TTS ($0.015–$0.040) + telephony per minute - the reason the range is $0.07–$0.31/min. SuperMIA Business is $0.104/min effective, everything in, so the number you model is the number you pay.
Voice + chat in one pool, not two meters
Retell now offers chat, but it's a separate per-message meter ($0.002+/msg plus per-message LLM) on top of voice. SuperMIA runs voice and chat from the same credit pool - 240 credits per voice minute or 40 credits per chat conversation, one invoice.
No concurrency surcharge
Retell includes 20 concurrent calls, then charges $8/line/month for each additional line - a 100-line outbound campaign adds $640/mo before a minute is billed. SuperMIA scales through credit-pool sizing with no per-line fee.
Compliance without per-feature meters
On Retell, PII removal (+$0.01/min), safety guardrails (+$0.005/min), and knowledge base (+$0.005/min) are metered add-ons. SuperMIA bundles compliance and safety - HIPAA-aligned with a BAA on eligible plans, plus SOC 2, GDPR, PCI DSS, and ISO 27001.
