| What matters | APIFleet | Telnyx AI Assistants |
|---|---|---|
| Starting point | $0.03 per connected AI minute Platform fee, billed per second | $0.05 / min Voice engine; LLM and telephony extra |
| Payment model | Prepaid usage. $10 minimum top-up. No monthly subscription or free credits. | Voice-engine usage plus model tokens and telephone charges. |
| Cost scope | AI providers and carrier charges are additional. Customer-owned keys are paid directly to providers. | The engine includes orchestration, hosted transcription and text-to-speech. Its published billing rounds each call to 60-second increments. |
| Working style | Configurable assistants, tools, knowledge, browser tests, simulations and call logs. | AI assistants alongside Telnyx telephony and model services. |
Using a carrier does not commit you to its agent platform.
Telnyx can provide telephone connectivity while a different platform runs the assistant. APIFleet also supports Telnyx carrier credentials. Compare the integrated assistant offering on its own terms: its engine includes speech services that must be added to APIFleet’s platform charge.
When Telnyx AI Assistants may fit
Evaluate Telnyx AI Assistants when an integrated telephony and voice-engine setup suits your operational model. Include the selected LLM and call destinations in the estimate.
When APIFleet may fit
Evaluate APIFleet when you want a separate assistant-management layer and provider choice while keeping your carrier relationship.
APIFleet currently limits new workspace access. Existing users can sign in; contact us about a new project. Carrier accounts, standalone previews, file transcription and simulation caller/judge models require customer-owned credentials.
Two workloads to price explicitly
These hypothetical examples assume exactly 1,000 or 10,000 connected AI minutes. They calculate APIFleet’s platform portion only; model, speech, carrier, numbers and any other service charges must be added.
| Workload | APIFleet platform arithmetic | Telnyx AI Assistants estimate |
|---|---|---|
| Pilot: 1,000 minutes | 1,000 × $0.03 = $30.00 | Apply the vendor’s published or quoted terms to the same provider stack and duration. |
| Operation: 10,000 minutes | 10,000 × $0.03 = $300.00 | Include subscriptions, allowances, overages, rounding and implementation work when applicable. |
A bundled vendor rate cannot be compared directly to the APIFleet platform portion. We do not infer Telnyx AI Assistants’s concurrency or seat limits from a minute rate; confirm them for your planned workload.
Run a one-assistant switching pilot
Before switching from Telnyx AI Assistants, recreate one assistant, replay its tool requests, test interruptions and transfers, then move one controlled route with a written rollback. Use the voice-agent migration checklist and conversation test plan with the vendor-specific checks below.
What to test before switching
- Check which costs belong to the carrier and which to the AI engine.
- Model short calls using each service’s actual billing increments.
- Validate number routing and transfers before changing a live configuration.
There is no universal one-click import. Map prompts, tools, credentials and routing explicitly, then run controlled calls. Our gradual migration guide gives you a sequence with a rollback boundary.
