## Plans

| Plan | Monthly | Annual | Billing | Notes | Source |
| --- | --- | --- | --- | --- | --- |
| ConversationRelay (usage-based) | $0 | — | per_minute | $0.07/min with no monthly platform fee and no published included minutes, described on the page as pay as you go with per-minute pricing. The rate covers Twilio-managed speech-to-text, text-to-speech and session orchestration while you bring your own LLM; there is no rate for a Twilio-supplied model because none is offered. Voice costs are calculated separately, so Programmable Voice minutes, phone numbers, SMS, WhatsApp and other channels bill under the existing Twilio account, as do your own LLM tokens and any post-call voice transcription. Adjacent Conversational AI meters on the same page, each billed on top if used: Conversation Orchestrator $0.0002 per 1K characters ingested; Conversation Intelligence $0.005 per 1K characters for Twilio-authored operators and $0.002 input / $0.018 output per 1K characters for custom operators; Conversation Memory profiles $0.005 per daily utilized profile plus $0.08 per 1K profile operations with the first 100K free monthly; Memory generation $0.0028 per 1K characters and $0.007 per recall; Enterprise Knowledge $0.018 per GB-hour storage and $0.005 per retrieval. | twilio.com |

## Price changes

No change record has cleared two sources yet, so nothing is published on the wire.

**Key features:** Sits directly on Twilio's Programmable Voice stack, so existing Twilio numbers, SIP trunks and call flows need no migration; Bring-your-own-LLM by design, which keeps model choice and token cost fully under the buyer's control; Integrates with Twilio Conversational Intelligence for agent observability on the same session, and with Conversation Memory for cross-session profiles; Single-vendor billing across voice, SMS and WhatsApp for omnichannel agents.

**Plan limits:** $0.07/min is the highest orchestration rate in this set and still excludes Programmable Voice minutes, phone numbers and LLM tokens; Bring-your-own-LLM is mandatory; no bundled model option is priced; Does not transcribe calls itself — voice transcription is a separate Twilio charge; The surrounding Conversational AI products (Orchestrator, Intelligence, Memory, Enterprise Knowledge) are each separately metered, several by the 1,000 characters, so a full agent build accumulates five or more line items; No monthly plan, no free allowance and no volume pricing published on the page; The pricing page makes no HIPAA, SOC 2 or GDPR claim for this product specifically, so all three are null.

Provenance: Re-verified against twilio.com/en-us/products/conversational-ai/pricing on 2026-09-10. The $0.07/min ConversationRelay rate is confirmed, with no monthly fee, no included minutes and no free allowance published, and the page confirms voice costs are calculated separately. ONE ADDITION: the draft omitted the other Conversational AI meters published on the same page, which a real agent build will touch — Conversation Orchestrator, Conversation Intelligence, Conversation Memory and Enterprise Knowledge. These are now itemised in notes. They are separate products rather than ConversationRelay plan tiers, so the single usage-based plan is retained. Compliance stays null: the page makes no HIPAA, SOC 2 or GDPR claim for this product.
