Voice platform
Smallest AI
Voice agent platform built on Smallest AI's own speech-to-text, text-to-speech and small language models.
Official Smallest AI console; new pay-as-you-go accounts start with $10 in credits.
Run agents on one vendor's own speech models
What you get
Host phone and web agents on Smallest AI's own speech and language models, with campaigns, knowledge bases and SIP support.
What to account for
Latency and compliance claims are vendor-reported, human transfer is unconfirmed, and HIPAA is a paid add-on.
What the platform provides
- Agent hosting
- Phone and web agents on the vendor's own speech and language models, with knowledge bases and outbound campaigns.
- Deployment
- Rented numbers or SIP trunks, with the speech models also sold as standalone APIs.
Connections & compatibility
- Connects with
- Plivo, Vonage, Twilio SIP, Telnyx SIP, LiveKit, Pipecat
Cost at your volume
Pay as you go lists $0.09-$0.21 per minute depending on the models chosen, plus a $0.01/min hosting fee, $10 per phone number per month and 20 concurrent calls. Enterprise is custom, from as low as $0.05/min. Knowledge-base storage and queries, PII removal, SMS and the HIPAA add-on are billed separately; confirm carrier costs for SIP trunks.
Before committing
Measure caller-to-agent latency on your own carrier, then fail a tool call and ask for a person. Confirm how transfer works before relying on it.
- What latency do you measure on our carrier and region, from caller speech to agent audio?
- Can the agent transfer to a person, and what happens when a tool call fails mid-call?
- What is our all-in monthly cost including hosting, numbers, knowledge base and add-ons?
- Can you share the SOC 2 report and BAA, and where are recordings stored and for how long?
Controls to confirm
Smallest AI states SOC 2 Type 2, ISO 27001, GDPR and HIPAA compliance, with HIPAA sold as a $1,000/month add-on and on-premise deployment on Enterprise. Request the reports and BAA, and verify recording retention, PII removal, subprocessors and data location before connecting customer systems. Morak has not audited these claims.
What to consider next
A different approach
Investigate Vapi if you want to choose each model and telephony provider yourself.

Consider Retell AI for a developer platform with more established phone-agent tooling.
