Voxtral 3 TTS Pricing: Check the Model Before You Budget
Updated October 28, 2026. Mistral’s Voxtral 3 launch page and Voxtral TTS 3 model card now both list $13 per million characters. The general API pricing page lists Voxtral TTS 3 at $13 and a separate Voxtral TTS model at $16 per million characters. This current check supersedes the article’s October 20 comparison; it does not establish when the documentation changed or what a particular account was billed. Confirm the exact model, provider and applicable rate before quoting a customer.
What the primary pages actually show
These are observations from public pages, not an account invoice or a tested API charge. The two model names also matter: the announcement calls the speech product Voxtral Speech 3; the linked model card is titled Voxtral TTS 3 and identifies voxtral-mini-tts-3-0.
- Checked October 28, 2026: Voxtral 3 announcement — Voxtral Speech 3, $13 per million characters; public launch figure, not an account quote.
- Checked October 28, 2026: Voxtral TTS 3 model card — voxtral-mini-tts-3-0, $13 per million characters; Public Preview / Premier v3.0.
- Checked October 28, 2026: general API pricing — Voxtral TTS 3, $13 per million characters; the separately listed Voxtral TTS entry is $16. Do not substitute one model’s rate for another.

Current official API pricing by model
The current pages distinguish model entries rather than establishing a current $13-versus-$16 disagreement for Voxtral TTS 3. We have not independently verified account billing or the earlier pages’ change history. Keep the model identifier and dated pricing evidence with your estimate, and confirm the commercial terms that apply to your account.
Turn a headline price into a usable estimate
Create a small cost sheet before choosing a rate. Record the provider you pay, the exact model identifier, the endpoint or deployment route, the region and service tier where relevant, the charging unit, and the date of the quote. Keep a copy of the applicable pricing or written confirmation alongside the estimate. An alias containing latest is less useful for a reproducible budget than a recorded model/version and a known alias policy.
Then estimate volume using your own scripts. Count the text your application actually submits for speech generation, including repeated answers or regenerated clips. Do not estimate the entire project from the number of calls alone: a short confirmation and a long explanation can have very different text lengths. Confirm the provider’s character-counting and retry rules rather than assuming how punctuation, failed requests or cached content are treated.
A transparent two-rate scenario—not a bill
For an illustrative workload of two million billable characters, a $13-per-million rate produces $26 of TTS usage; a $16-per-million rate produces $32. The $6 difference illustrates the effect of choosing different model rates, not a current discrepancy in the Voxtral TTS 3 model card. It is not a quote, a claim about your character count, or an estimate of the complete voice-agent project. Taxes, discounts and other services are not included.
TTS is only one part of a voice agent
Mistral describes a pipeline with speech recognition, a separate reasoning model and speech output. A character-based TTS line therefore should not be presented as the whole conversation cost. Budget separately for transcription, reasoning, telephony or transport, connected services and your own operating work where applicable. The launch directs teams seeking the full on-premises or private-cloud stack to contact Mistral; that is not an automatic public-weight licence.
A practical pilot handoff
Use a small, authorised test set before scaling: one short response, one longer response, a repeated request and an interrupted conversation. Record the model selected, the usage reported and the charges when they become available. Reconcile those records with the provider’s terms before multiplying the pilot result into a monthly forecast. We have not performed that billing test for this article.
For a customer proposal, label unconfirmed prices as assumptions and show which costs are excluded. Keep the first pilot reversible: a low spend limit, a narrow use case and a human review point make a mistaken assumption easier to detect. The useful decision is to tie each estimate to the exact model and service you will actually buy.
